How to disable manual input in a Telerik RadDatePicker

Question

I am using a Telerik RadDatePicker, and I want to disable input by the user, but they should be able to select from the calender.

<telerik:RadDatePicker Culture="{Binding GetLanguage}" x:Name="startDate" 
                       Margin="0,5,0,5" HorizontalAlignment="Left"
                       VerticalAlignment="Center" Grid.Column="1" TabIndex="2"
                       MinWidth="120" Width="120" Height="Auto" MaxHeight="25"
                       KeyDown="filterDate_KeyDown" >
</telerik:RadDatePicker>

I have used KeyDown but it did not help.

Answer 1

The PreviewKeyDown event exists exactly for this sort of thing.

private void spacebarHandler_PreviewKeyDown(object sender, KeyEventArgs e)
 {
if (e.Key == Key.Space)
    e.Handled = true;
}
