  I'm using the following version, 2010.3.1110.1040 and have notice the following issues with the RadMaskedTextBox.
  
  1.  If the user selects the contents of the maskedtextbox and hits delete, nothing happens. 
  2.  The user may remove all but one character when using the backspace key.
  
  Any ideas would be greatly appreciated.
  
  

  private void txtArrNotice_ValueChanging(object sender, RadMaskedTextBoxValueChangingEventArgs e)

          {

              string newValue = e.NewMaskedText;

              Regex pattern = new Regex(@"(^[a-zA-Z0-9]+$)");

              e.Handled = !pattern.IsMatch(newValue);

          }

    

    

  <telerik:RadMaskedTextBox x:Name="txtArrNotice" 

             EmptyContent="Enter Arrival Notice#" 

             Style="{StaticResource ArrivalMaskedTextBoxStyle}" 

             MaskType="None" 

              ValueChanging="txtArrNotice_ValueChanging"/>

  Hi Tamiko,

   Commenting the code in the ValueChanging event handler makes the MaskTextBox work as expected. So both of your scenarios are result from you regex matching logic. Please let us know if you need further assistance.
