Hi,
We've just upgraded to Q2 2014 and replaced retired RadMaskedTextBox with RadMaskedTextInput with these properties set
<Setter Property="Mask" Value="###-###-####" />
<Setter Property="EmptyContent" Value="___-___-____" />
<Setter Property="IsClearButtonVisible" Value="False" />
<Setter Property="AllowInvalidValues" Value="False"></Setter>

Two issues:
1. Mask is set to ###-###-####. However, it allows for spaces.
2. I can't paste more than once into it. First Paste works fine, but then if I delete the contents and paste again  with Context Menu Paste, nothing happens.  If I use Ctrl+V, it does paste but only after second try.

Is there a way to fix both?

The heading should've said RadMaskedTextInput. Is there a way to edit/delete the posting in your forum??

Hi Anna,

Space is allowed in RadMaskedTextInput and disallowed in RadMaskedNumericInput despite of the Mask that is set. If you need only numeric input and disallow the space key, we encourage you to use the RadMaskedNumericInput.
As for the second issue, we logged it in our feedback portal where you can track its status.
Please do not worry for the name of the Thread, the forum name and the explanations are enough. You are not able to edit an already posted name of a thread.
