RadMasketTextInput deletes first character

[Ádám]

Hi there!

 

I just found an issue with RadMaskedTextInput that is present in the newest WPF Demos, too. In my scenario, I tried it with no mask. Simply type some word into the control, select all with CTRL+A, then hit a letter on the keyboard followed by a space. If you fast enough (but you should not be so fast, just something like experienced-typewriter-fast) your letter will be overwritten by the whitespace that followed it.

 

If you can't reproduce the issue, I can post a video about it.

Hello Ádám,

Thank you for reporting this. We've logged it in our feedback portal and we also updated your telerik account points.
As a workaround, you can try subscribing for PreviewKeyDown like so:

private void RadMaskedTextInput_PreviewKeyDown(object sender, KeyEventArgs e)
       {
           if (this.input.Value != null && this.input.SelectionLength == this.input.Value.Length && this.input.SelectionLength > 0)
           {
               this.input.ClearCommand.Execute(null);
           }
       }

Hey Petar,

 

It seems to work with your workaround. :) Thanks!

Hi Petar,
Sorry, it's still not okay. The original issue is gone, but with your workaround if I select the whole text then I press Return (or anything including the modifier keys) the text will be cleared.

Hello Ádám,

Thanks for this note. I guess inheritance will do a better job:

public class CustomInput : RadMaskedTextInput
   {
       protected override void OnKeyDown(KeyEventArgs e)
       {
           if (this.Value != null && this.SelectionLength == this.Value.Length && this.SelectionLength > 0)
           {
               this.ClearCommand.Execute(null);
           }
           base.OnKeyDown(e);
       }
   }
