DateInput

Bug Report
DateInput does not accept null as a valid value when using a standard date format string or a week day
This is a continuation of public item DatePicker, TimePicker and DateTimePicker should accept null value as valid when bound to nullable DateTime
The problem persist when:
- The component Format includes a week day.
- The component Format is set with a standard date format string (d, D, g, etc.)
Test page with workarounds:
Bug due to week day format string inconsistency between .NET and JavaScript (dddd vs EEEE):
<TelerikDateTimePicker @bind-Value="@SelectedTime"
ShowClearButton="true"
Width="360px">
<DateTimePickerFormatPlaceholder Weekday="week" />
</TelerikDateTimePicker>
<br />
<br />
Bug due to usage of a standard date format string:
<TelerikDatePicker @bind-Value="@SelectedTime"
ShowClearButton="true"
Format="d"
Width="360px">
<DateTimePickerFormatPlaceholder Day="dd" Month="mm" Year="yyyy" />
</TelerikDatePicker>
@code {
private DateTime? SelectedTime = DateTime.Now;
}
