I would like the input to originally appear empty, and only show the mask if the user begins entering a value.  If the user removes the value, the mask will again disappear.

Is this functionality possible with this control?

Hello,

You can achieve this behavior by setting the HideOnBlur  property of the RadMaskedTextBox to "True"
Here is a sample code:

aspx:
<telerik:RadMaskedTextBox ID="RadMaskedTextBox1" runat="server" HideOnBlur="True" Mask="(###) ###-####">
</telerik:RadMaskedTextBox>

Thanks,
Princy.

This function HideOnblur does not work when I have a RequiredFieldValidator attached to the RadMaskedTextBox. It always display the mask. Is there a work around?
Thanks.

Hello Vincent,

The Validator itself does not affect the behaviour of RadMaskedTextBox and its HideOnBlur property.

It is possible that you have set SetFocusOnError="true" for your Validator, in this case when you try to blur, the validator gets back the focus to the input element of RadMaskedTextBox, and since the input is in focus, it will again display the mask.
Make sure you have set SetFocusOnError="false" for your Validator to avoid this problem.
