Pasting in MaskedTextInput should work like in TextBox
Currently, performing consecutively paste operation does not work like in TextBox. In TextBox the strings are concatenated but in MaskedTextInput the caret is in the beggining and only the first paste is successful.

I am using Q1 2014. Is that the problem? Which version Mask="" works?

Hi Rousseau,

Could you please open a support thread in our system describing what stops you from using no-mask (Mask="") where the consecutive paste is working out of the box ?

This way we will be able to provide a suitable solution for you faster. Thank you for your understanding.

The given alternative did not work. The SelectionStart coming most of the time greater than the length value of the text.

Does anyone else have a working alternative This is really bad if we cannot support existing/default behavior of an input control.

Consecutive Paste operation works in No-Masked scenario (Set Mask=""). Changing the paste behavior in masked scenarios would be a breaking change for some of our clients. We are closing this feature request.

This issue must be fixed! It's base functionality that works everywhere, but not in Telerik masked input.

We would really like this functionality as well.

Bump - This really needs to be developed.

Hi Demir,

The issue is still not scheduled.

However, you can workaround it by inheriting RadMaskedTextInput and override HandlePaste method:

  public class CustomTextInput : RadMaskedTextInput
        protected override void HandlePaste()
            string txt = Clipboard.GetText();
            this.Value += txt;            
Of course in this method you must also include border cases and the SelectionStart (the position of the caret).
Additionally, because this method fires twice, you can remove the binding to ApplicationCommands.Paste like so:

  private void input_Loaded(object sender, RoutedEventArgs e)
            TextBox tBox = (sender as RadMaskedInputBase).ChildrenOfType<TextBox>().FirstOrDefault();
            if (tBox != null)

We hope this could be a good starting point for a workaround.

Is there any progress on this? Or a better workaround?

The workaround of pasting the text to be copied in notepad, copying the old text from the destination RadMaskedTextInput to notepad too, cutting the text to be copied, pasting it somewhere, copying the entire text, pasting it back in the RadMaskedTextInput is cumbersome and errorprone.
