    FileUpload Component Samples

    + +

    The FileUpload control lets users select files for upload, emulating the ASP.NET Web Forms + <asp:FileUpload> control. It renders as an HTML <input type="file">.

    + +
    + + +

    Basic File Upload

    +

    A simple file picker, just like the default Web Forms FileUpload:

    + +
    + +
    +
    + +

    Code:

    +
    <FileUpload @@ref="basicUpload" />
+<Button Text="Check File" OnClick="CheckBasicFile" />
+
+@@code {
+    FileUpload basicUpload;
+    void CheckBasicFile()
+    {
+        if (basicUpload.HasFile)
+            status = $"Selected: {basicUpload.FileName}";
+    }
+}
    + +
    + + +

    Restrict to Images Only

    +

    Use Accept to limit file types, similar to adding a RegularExpressionValidator + in Web Forms:

    + +
    + +
    + +

    Code:

    +
    <FileUpload Accept="image/*" />
    + +
    + +

    Accept Specific File Types

    +

    Restrict to PDF and Word documents:

    + +
    + +
    + +

    Code:

    +
    <FileUpload Accept=".pdf,.doc,.docx" />
    + +
    + + +

    Multiple File Selection

    +

    Set AllowMultiple="true" to allow selecting more than one file at a time:

    + +
    + +
    +
    + +

    Code:

    +
    <FileUpload AllowMultiple="true" />
    + +
    + + +

    Disabled FileUpload

    +

    Set Enabled="false" to prevent interaction, just like Web Forms:

    + +
    + +
    + +

    Code:

    +
    <FileUpload Enabled="false" />
    + +
    + + +

    Styled FileUpload

    +

    Apply styling with CssClass, BackColor, and Width:

    + +
    + +
    + +

    Code:

    +
    <FileUpload CssClass="form-control"
+            BackColor="WebColor.LightCyan"
+            Width="Unit.Pixel(400)" />
    + +
    + + +

    Visibility Toggle

    +

    Use the Visible property to show/hide, matching Web Forms behavior:

    + +
    + +
    + +
    + +

    Code:

    +
    <FileUpload Visible="@@uploadVisible" />
    + +@code { + private FileUpload basicUpload; + private FileUpload multiUpload; + private string basicStatus; + private string multiStatus; + private bool uploadVisible = true; + + private void CheckBasicFile() + { + basicStatus = basicUpload.HasFile + ? $"Selected: {basicUpload.FileName}" + : "No file selected."; + } + + private void CheckMultiFiles() + { + multiStatus = multiUpload.HasFile + ? $"File(s) ready for upload." + : "No files selected."; + } + + private void ToggleUploadVisibility() + { + uploadVisible = !uploadVisible; + } +} diff --git a/samples/AfterBlazorServerSide/Components/Pages/ControlSamples/ImageMap/Index.razor b/samples/AfterBlazorServerSide/Components/Pages/ControlSamples/ImageMap/Index.razor new file mode 100644 index 00000000..edd22fda --- /dev/null +++ b/samples/AfterBlazorServerSide/Components/Pages/ControlSamples/ImageMap/Index.razor @@ -0,0 +1,276 @@ +@page "/ControlSamples/ImageMap" +@using BlazorWebFormsComponents +@using BlazorWebFormsComponents.Enums + +ImageMap Sample + +

    ImageMap Component Samples

    + +

    The ImageMap control displays an image with clickable hot spot regions, emulating + <asp:ImageMap> from ASP.NET Web Forms. Hot spots can navigate to URLs + or raise postback events, just like in Web Forms.

    + +
    + + +

    Navigation Hot Spots

    +

    Click a region to navigate. This mirrors the Web Forms HotSpotMode.Navigate behavior:

    + +
    + +
    + +

    The image above has three hot spots defined:

    +
      +
    • Left rectangle (0,0 → 130,200) — navigates to the Button sample
      • +
    • Center circle (200,100 radius 60) — navigates to the CheckBox sample
      • +
    • Right rectangle (270,0 → 400,200) — navigates to the Image sample
      • +
    + +

    <ImageMap ImageUrl="image.png"
+          AlternateText="Navigation demo"
+          HotSpotMode="HotSpotMode.Navigate"
+          HotSpots="@@navigationHotSpots" />
+
+@@code {
+    List<HotSpot> navigationHotSpots = new()
+    {
+        new RectangleHotSpot {
+            Left = 0, Top = 0, Right = 130, Bottom = 200,
+            NavigateUrl = "/ControlSamples/Button",
+            AlternateText = "Button Samples"
+        },
+        new CircleHotSpot {

+            AlternateText = "CheckBox Samples"
+        }
+    };
+}
    + +
    + + +

    PostBack Hot Spots

    +

    Click a region to trigger a server-side event with a PostBackValue. + This is equivalent to handling ImageMap.Click in Web Forms code-behind:

    + +
    + + + @if (!string.IsNullOrEmpty(clickedRegion)) + { +
    + You clicked: @clickedRegion +
    + } +
    + +

    Code:

    +
    <ImageMap HotSpotMode="HotSpotMode.PostBack"
+          HotSpots="@@postBackHotSpots"
+          OnClick="HandleHotSpotClick" />
+
+@@code {
+    void HandleHotSpotClick(ImageMapEventArgs e)
+    {
+        clickedRegion = e.PostBackValue;
+    }
+}
    + +
    + + +

    Mixed Hot Spot Modes

    +

    Each hot spot can override the default HotSpotMode. This image has a + navigate region, a postback region, and an inactive region:

    + +
    + + + @if (!string.IsNullOrEmpty(mixedClickResult)) + { +
    @mixedClickResult
    + } +
    + +

    Hot spot behaviors on this image:

    +
      +
    • Left third — Navigate to home page
      • +
    • Center — PostBack (raises click event with value "center")
      • +
    • Right third — Inactive (no action)
      • +
    + +

    Code:

    +
    new RectangleHotSpot {
+    Left = 0, Top = 0, Right = 150, Bottom = 180,
+    HotSpotMode = HotSpotMode.Navigate,
+    NavigateUrl = "/",
+    AlternateText = "Home"
+},
+new CircleHotSpot {
+    X = 225, Y = 90, Radius = 50,
+    HotSpotMode = HotSpotMode.PostBack,
+    PostBackValue = "center",
+    AlternateText = "Click Me"
+},
+new RectangleHotSpot {
+    Left = 300, Top = 0, Right = 450, Bottom = 180,
+    HotSpotMode = HotSpotMode.Inactive,
+    AlternateText = "Inactive Region"
+}
    + +
    + + +

    Polygon Hot Spot

    +

    Use PolygonHotSpot for irregularly shaped regions, defined by coordinate pairs:

    + +
    + + + @if (!string.IsNullOrEmpty(polygonClickResult)) + { +
    @polygonClickResult
    + } +
    + +

    Code:

    +
    new PolygonHotSpot {
+    Coordinates = "150,20,280,180,20,180",
+    PostBackValue = "triangle",
+    AlternateText = "Triangle region"
+}
    + +
    + + +

    Accessibility

    +

    Always provide AlternateText on both the ImageMap and each HotSpot for screen readers. + Use GenerateEmptyAlternateText for purely decorative images:

    + +
    + +

    Decorative image with empty alt text.

    DetailsView Component Samples

    + +

    The DetailsView control displays a single record from a data source in a table layout, + with one row per field. In Web Forms this was <asp:DetailsView>.

    + +
    + +

    Auto-Generated Rows

    +

    When AutoGenerateRows is true (the default), the DetailsView + automatically creates a row for each public property on the data item.

    + + + +

    Code:

    +
    <DetailsView ItemType="Customer"
+             Items="@@_customers"
+             AutoGenerateRows="true"
+             HeaderText="Customer Details"
+             GridLines="GridLines.Both" />
    + +
    + +

    Paging Between Records

    +

    Set AllowPaging="true" to display a pager row that lets users navigate + between individual records in the data source — one record at a time.

    + + + +

    Current page changed @_pageChangeCount time(s).

    + +

    Code:

    +
    <DetailsView ItemType="Customer"
+             Items="@@_customers"
+             AllowPaging="true"
+             AutoGenerateRows="true"
+             HeaderText="Browse Customers"
+             PageIndexChanged="HandlePageChanged" />
    + +
    + +

    Edit Button & Mode Switching

    +

    Set AutoGenerateEditButton="true" to add an Edit link in the command row. + Clicking Edit switches the DetailsView to Edit mode. Click Update or Cancel to return to ReadOnly mode. + Handle the ModeChanging and ItemUpdating events to integrate with your data store.

    + + + +

    @_statusMessage

    + +

    Code:

+             HeaderText="Editable Customer"
+             ModeChanging="HandleModeChanging"
+             ItemUpdating="HandleUpdating" />
+
+@@code {
+    void HandleModeChanging(DetailsViewModeEventArgs e)

+}
    + +
    + +

    Empty Data

    +

    When the data source has no items, the EmptyDataText is displayed.

    + + + +

    Code:

    +

    PasswordRecovery Component Samples

    + +

    The PasswordRecovery control provides a multi-step password recovery flow: + enter a username, answer a security question, and receive a success confirmation. + In Web Forms this was <asp:PasswordRecovery>.

    + +
    + +

    Default PasswordRecovery

    +

    The default layout provides a username step, a security question step, and a success step. + Handle OnVerifyingUser to validate the username and set the security question + via the SetQuestion method. Handle OnVerifyingAnswer to verify the answer.

    + + + +

    @_statusMessage

    + +

    Code:

    + +
    + +

    Custom Text Properties

    +

    Customize labels, titles, and messages for each step using the text properties.

    + + + +

    Code:

    +
    <PasswordRecovery ID="PasswordRecovery2"
+    UserNameTitleText="Password Reset"
+    UserNameInstructionText="Please enter your email address below."
+    UserNameLabelText="Email:"

+    OnVerifyingAnswer="HandleVerifyingAnswer" />
    + +
    + +

    With Help Link

    +

    Use HelpPageText and HelpPageUrl to add a help link below the form.

+  - Pages with multiple PasswordRecovery instances require ID-specific selectors (`#PasswordRecovery1_SubmitButton`) not suffix selectors (`input[id$='_SubmitButton']`) to avoid strict mode violations.
+  - After a multi-step Blazor Server form flow, the final `_statusMessage` reflects the LAST handler that sets it. For PasswordRecovery step 2→3, `OnVerifyingAnswer` sets one message, then `OnSendingMail` overwrites it — test must assert on the final value.
+  - `PressSequentiallyAsync` + Tab blur works reliably for Blazor Server `InputText` binding on dynamically re-rendered DOM elements.

+### 2026-02-12: Milestone exit criteria — samples and integration tests mandatory
+
+**By:** Jeffrey T. Fritz
+**What:** Every milestone/sprint must meet ALL of the following exit criteria before submission for review:
+1. **Samples for every feature** — Every feature of every component created or modified in the sprint must have a corresponding sample page demonstrating it
+2. **Integration tests for every sample** — Every sample page added must have at least one Playwright integration test verifying its interactive behavior
+3. **All integration tests pass** — 100% of integration tests (both new and pre-existing) must pass before the sprint is submitted
+**Why:** Sprint 3 exposed gaps where components shipped without full sample coverage and integration tests. This gate ensures no sprint is declared complete until the full chain — component → sample → integration test → green — is verified. This is a permanent policy for all future sprints.

 and move ImageMap to Navigation

- Merged two 'Utility Features' TreeNode branches into one (ID Rendering + PageService)
- Moved ImageMap from Editor Components to Navigation Components per team decision
- Alphabetized Editor Components entries (Button before Calendar, HyperLink before Image)

 alphabetize all navigation

- Create DataBinder sample: Eval(), shorthand Eval, formatted Eval, modern alternative
- Create ViewState sample: dictionary API with counter demo, settings form, modern alternative
- Alphabetize all NavMenu TreeView branches, ComponentList columns, and mkdocs.yml nav
- Move ImageMap from Editor Controls to Navigation Controls in ComponentList and mkdocs
- Add Utility Features section to ComponentList with all 4 entries
- Add 4 integration tests: 2 smoke + 2 interaction (120/120 passing)

   - Pages with multiple PasswordRecovery instances require ID-specific selectors (`#PasswordRecovery1_SubmitButton`) not suffix selectors (`input[id$='_SubmitButton']`) to avoid strict mode violations.
   - After a multi-step Blazor Server form flow, the final `_statusMessage` reflects the LAST handler that sets it. For PasswordRecovery step 2→3, `OnVerifyingAnswer` sets one message, then `OnSendingMail` overwrites it — test must assert on the final value.
   - `PressSequentiallyAsync` + Tab blur works reliably for Blazor Server `InputText` binding on dynamically re-rendered DOM elements.
+
+## 2026-02-12: DataBinder and ViewState utility feature integration tests
+
+- Added smoke tests in `ControlSampleTests.cs`:
+  - New "Utility Features" theory section with `[InlineData("/ControlSamples/DataBinder")]` and `[InlineData("/ControlSamples/ViewState")]`
+- Added 2 interaction tests in `InteractiveComponentTests.cs`:
+  - `DataBinder_Eval_RendersProductData` — verifies the DataBinder sample page renders product data ("Laptop Stand", "USB-C Hub", "Mechanical Keyboard") via Repeater with DataBinder.Eval(). Asserts at least 3 `` rows present.
+  - `ViewState_Counter_IncrementsOnClick` — verifies the ViewState sample page's "Click Me (ViewState)" button increments a counter stored in ViewState. Clicks twice and verifies counter reaches 1 then 2.
+- Build: 0 errors. All 120 integration tests passing (116 existing + 4 new), 0 failures.
+- Key learnings:
+  - DataBinder sample uses `OnAfterRender(firstRender)` to call `DataBind()` on 4 Repeater instances — data only appears after first render, but NetworkIdle wait handles this.
+  - ViewState sample button text "Click Me (ViewState)" distinguishes it from the "Click Me (Property)" button in section 3. Used `GetByRole(AriaRole.Button, new() { Name = "Click Me (ViewState)" })` for precise targeting.
+  - Both pages include `
    ` blocks with sample code — assertions use `page.ContentAsync()` for text presence rather than strict locators to avoid matching code samples vs rendered content where appropriate.

 📌 Team update (2026-02-12): Sprint 3 gate review — DetailsView and PasswordRecovery APPROVED. 50/53 components (94%). — decided by Forge
 📌 Team update (2026-02-12): LoginControls sample pages MUST include `@using BlazorWebFormsComponents.LoginControls` — root _Imports.razor doesn't cover sub-namespaces. Never use external image URLs in samples; use local SVGs. — decided by Colossus
+
+### Utility Feature Sample Pages — DataBinder and ViewState
+
+- **DataBinder sample** (`Components/Pages/ControlSamples/DataBinder/Index.razor`): Demonstrates all three `Eval()` signatures with a Repeater — `DataBinder.Eval(container, "Prop")`, shorthand `Eval("Prop")` via `@using static`, and `Eval("Prop", "{0:C}")` with format strings. Each section has live demo + code block. Section 4 ("Moving On") shows the modern `@context.Property` approach side by side.
+- **ViewState sample** (`Components/Pages/ControlSamples/ViewState/Index.razor`): Uses `@ref` to a Panel component to demo `ViewState.Add`/`ViewState["key"]` dictionary API. Shows a click counter and a multi-key settings form stored in ViewState, then contrasts with the modern C# field/property approach. `#pragma warning disable CS0618` suppresses the Obsolete warnings for the demo code.
+- **Navigation fixes applied:** NavMenu.razor Login Components reordered (Login before LoginName), DataBinder and ViewState added to Utility Features (alphabetical: DataBinder, ID Rendering, PageService, ViewState). ComponentList.razor fixed: HyperLink moved before Image in Editor Controls, ImageMap removed from Editor Controls and added to Navigation Controls (per team decision), Utility Features column added. mkdocs.yml: ImageMap removed from Editor Controls nav (already in Navigation Controls).
+- **Widget model reused:** DataBinder sample reuses `SharedSampleObjects.Models.Widget` with inline data (Laptop Stand, USB-C Hub, Mechanical Keyboard) for a product catalog demo.
+- **Build verified:** `dotnet build` passes with 0 compilation errors (Debug config). Release config has a known transient Nerdbank.GitVersioning file-copy issue unrelated to this work.

    DataBinder Utility

    + +

    The DataBinder class provides backward-compatible Eval() methods + that emulate the Web Forms data binding syntax. It is marked [Obsolete] and + should be migrated away from — see the Moving On section below.

    + +
    + +

    1. DataBinder.Eval with a Repeater

    +

    Use DataBinder.Eval(Container.DataItem, "PropertyName") to bind data + inside a Repeater template, just like Web Forms.

    + + + + + + + + + + + + + + + + + + + + +
    IDNamePrice
    @DataBinder.Eval(Item, "Id")@DataBinder.Eval(Item, "Name")@DataBinder.Eval(Item, "Price")
    + +

    Code:

    +
    @@using BlazorWebFormsComponents
+
+<Repeater Context="Item" ItemType="Widget">
+    <ItemTemplate>
+        <tr>
+            <td>@@DataBinder.Eval(Item, "Id")</td>
+            <td>@@DataBinder.Eval(Item, "Name")</td>
+            <td>@@DataBinder.Eval(Item, "Price")</td>
+        </tr>
+    </ItemTemplate>
+</Repeater>
    + +
    + +

    2. Shorthand Eval with Static Import

    +

    Add @@using static BlazorWebFormsComponents.DataBinder to use + the shorter Eval("PropertyName") syntax — closer to the Web Forms + <%# Eval("PropertyName") %> pattern.

    + +@using static BlazorWebFormsComponents.DataBinder + + + + + + + + + + + + + + + + + + + + +
    IDNamePrice
    @Eval("Id")@Eval("Name")@Eval("Price")
    + +

    Code:

    +
    @@using static BlazorWebFormsComponents.DataBinder
+
+<Repeater Context="Item" ItemType="Widget">
+    <ItemTemplate>
+        <tr>
+            <td>@@Eval("Id")</td>
+            <td>@@Eval("Name")</td>
+            <td>@@Eval("Price")</td>
+        </tr>
+    </ItemTemplate>
+</Repeater>
    + +
    + +

    3. Eval with Format Strings

    +

    Use Eval("PropertyName", "{0:C}") to apply .NET format strings, + just like <%# Eval("Price", "{0:C}") %> in Web Forms.

    + + + + + + + + + + + + + + + + + + +
    NamePrice (formatted)
    @Eval("Name")@Eval("Price", "{0:C}")
    + +

    Code:

    +
    <Repeater Context="Item" ItemType="Widget">
+    <ItemTemplate>
+        <tr>
+            <td>@@Eval("Name")</td>
+            <td>@@Eval("Price", "{0:C}")</td>
+        </tr>
+    </ItemTemplate>
+</Repeater>
    + +
    + +

    4. Moving On — Use @@context Directly

    +

    DataBinder.Eval is marked [Obsolete]. In Blazor, you have + direct access to the strongly-typed @@context (or your named Context + variable) inside templates. This is simpler, faster, and gives you compile-time checking.

    + + + + + + + + + + + + + + + + + + + + +
    IDNamePrice
    @Item.Id@Item.Name@Item.Price.ToString("C")
    + +

    Code:

    +
    @@ No DataBinder needed — just use the context variable directly!
+
+<Repeater Context="Item" ItemType="Widget">
+    <ItemTemplate>
+        <tr>
+            <td>@@Item.Id</td>
+            <td>@@Item.Name</td>
+            <td>@@Item.Price.ToString("C")</td>
+        </tr>
+    </ItemTemplate>
+</Repeater>
    + +

    Why migrate? The @@context.Property approach gives you + IntelliSense, compile-time type safety, and eliminates the reflection overhead of + DataBinder.Eval.

    ViewState Utility

    + +

    In Web Forms, ViewState was a dictionary on every control that persisted + values across postbacks. In this library, every component inheriting + BaseWebFormsComponent exposes a ViewState property of type + Dictionary<string, object> for migration compatibility. + It is marked [Obsolete] — see Moving On below.

    + +
    + +

    1. ViewState API — Add and Retrieve Values

    +

    Access ViewState on any component via a @@ref reference. + Use ViewState.Add("key", value) or ViewState["key"] = value + to store values, and cast when retrieving.

    + + +

    Click count (stored in ViewState): @_viewStateClickCount

    + +     + +

    Code:

    +
    <Panel @@ref="_panel">
+    <p>Click count: @@_viewStateClickCount</p>
+    <button @@onclick="IncrementViewState">Click Me</button>
+</Panel>
+
+@@code {
+    Panel _panel;
+    int _viewStateClickCount = 0;
+
+    void IncrementViewState()
+    {
+        // Store value in ViewState
+#pragma warning disable CS0618
+        _panel.ViewState["ClickCount"] = _viewStateClickCount + 1;
+
+        // Retrieve value from ViewState
+        _viewStateClickCount = (int)_panel.ViewState["ClickCount"];
+#pragma warning restore CS0618
+    }
+}
    + +
    + +

    2. ViewState with Multiple Keys

    +

    ViewState can hold multiple named values, just like Web Forms. Here we store + a name and a color preference.

    + + +

    + + +

    +

    + + +

    + + +

    + Stored — Name: @_storedName, Color: @_storedColor +

    +     + +

    Code:

    +
    #pragma warning disable CS0618
+// Save
+_settingsPanel.ViewState["UserName"] = _nameInput;
+_settingsPanel.ViewState["FavColor"] = _colorInput;
+
+// Load
+_storedName = _settingsPanel.ViewState["UserName"] as string;
+_storedColor = _settingsPanel.ViewState["FavColor"] as string;
+#pragma warning restore CS0618
    + +
    + +

    3. Moving On — Use C# Properties Instead

    +

    ViewState is marked [Obsolete]. In Blazor, component state + is simply C# fields or properties — no dictionary indirection needed. This is type-safe, + faster, and idiomatic Blazor.

    + + +

    Click count (C# field): @_propertyClickCount

    + +     + +

    Code (the modern way):

    +
    @@code {
+    // Just use a C# field — no ViewState needed!
+    private int _clickCount = 0;
+
+    void IncrementProperty()
+    {
+        _clickCount++;
+    }
+}
    + +

    Why migrate? C# fields and properties give you type safety at compile time, + avoid casting from object, and are the standard Blazor pattern for component state.

    + +@code { + private Panel _panel = default!; + private Panel _settingsPanel = default!; + + private int _viewStateClickCount = 0; + private int _propertyClickCount = 0; + + private string _nameInput = ""; + private string _colorInput = ""; + private string _storedName = "(none)"; + private string _storedColor = "(none)"; + +#pragma warning disable CS0618 + private void IncrementViewState() + { + _panel.ViewState["ClickCount"] = _viewStateClickCount + 1; + _viewStateClickCount = (int)_panel.ViewState["ClickCount"]; + } + + private void SaveToViewState() + { + _settingsPanel.ViewState["UserName"] = _nameInput; + _settingsPanel.ViewState["FavColor"] = _colorInput; + LoadFromViewState(); + } + + private void LoadFromViewState() + { + _storedName = _settingsPanel.ViewState.ContainsKey("UserName") + ? _settingsPanel.ViewState["UserName"] as string ?? "(none)" + : "(none)"; + _storedColor = _settingsPanel.ViewState.ContainsKey("FavColor") + ? _settingsPanel.ViewState["FavColor"] as string ?? "(none)" + : "(none)"; + } +#pragma warning restore CS0618 + + private void IncrementProperty() + { + _propertyClickCount++; + } +}
