How to set null value in DateTimeEdit control ?

1 min read

If you want to set the null value for WPF DateTimeEdit control, you need to use the NullValue property. You can enable it only by setting the IsEmptyDateEnabled property to true and ShowMaskOnNullValue property to false. If the ShowMaskOnNullValue property true, then datetime mask is shown.

XAML

<syncfusion:DateTimeEdit x:Name="dateTimeEdit" Height="23" 
    Text="DateTimeEdit" TextWrapping="Wrap" Width="150"
    IsEmptyDateEnabled="True" IsVisibleRepeatButton="True"
    NullValue="{x:Null}" NoneDateText="No date is selected" ShowMaskOnNullValue="True" />

DateTimeEdit dateTime = new DateTimeEdit();
dateTime.Height = 25;
dateTime.Width = 150;
dateTime.IsEmptyDateEnabled = true;
dateTime.IsVisibleRepeatButton = true;
dateTime.NullValue = null;
dateTime.NoneDateText = "No date is selected";
dateTime.ShowMaskOnNullValue = false;
this.Content = dateTime;
