Problem with RadDatePicker LostFocus Event.

[SivaPrasad Bevara]

Hi,

I have a RadDatePicker control in my application.

I need to disable the RadDatePicker control whenever it lost the focus (when we do tab out from the control). I have written the code to disable the control in the LostFocus event.

But it is Disabling the control even I click on the Calender button also.

I mean it is firing the lost focus event first when I click on the Calender button.

Following is the sample code which I am using.

<StackPanel x:Name="LayoutRoot" Background="White">
        <TelerikInput:RadDatePicker x:Name="Pick" Width="100" Height="20" LostFocus="Pick_LostFocus"         DropDownOpened="Pick_DropDownOpened"></TelerikInput:RadDatePicker>
    </StackPanel>

       private void Pick_LostFocus(object sender, RoutedEventArgs e)
        {
            Pick.IsEnabled = false;
        }

        private void Pick_DropDownOpened(object sender, RoutedEventArgs e)
        {   }

Please help.

Hi,

Thank you, It seems the above problem is fixed in the Q3 release.

But I am facing another problem with the LostFocus event. I am using the Telerik "2010.3.1129.1040" version of controls.

RadDatePicker firing Lost Focus event, when it got focus from another RadDatePicker control.

Following is the code which I am using.

 <StackPanel x:Name="LayoutRoot" Background="White" Orientation="Vertical">
        <TelerikInput:RadDatePicker x:Name="Pick1" Width="100" Height="20" Margin="10,10" LostFocus="Pick_LostFocus"></TelerikInput:RadDatePicker>
        <TelerikInput:RadDatePicker x:Name="Pick2" Width="100" Height="20" Margin="10,10" LostFocus="Pick_LostFocus"></TelerikInput:RadDatePicker>
  </StackPanel>

    private void Pick_LostFocus(object sender, RoutedEventArgs e)
        {  }

Follow the below steps:
Select some date for the first DatePicker. If you tab out from the first control, then it is firing the LostFocus event of Pick1 and Pick2 controls.

Please help.

Hello SivaPrasad Bevara,

This is an expected behavior. When you hit the control it gets the focus first and then passes it to the TextBox in it. That is the reason the lost focus appearing. You may need to perform a check if you are still in the control. Unlike WPF in Silverlight there is no such property that can tell you if the focus is somewhere in your control. (WPF - UIElement.IsKeyboardFocusWithin).

All the best,
