Fix filter menu handling for OrderDate and update sample link

[Prathappr]

Updated filter menu sample link and added handling for null OrderDate filters.

Previous code -After filtering and then clearing the filter by clicking the filter clear button, the grid’s filter is cleared, but the selected value remains in the SfDateRangePicker.

To overcome this issue, we handled the filtering event. When the clear button is clicked and the filtering event is triggered, we manually clear the value in the SfDateRangePicker.
