Backspace in a RadMaskedCurrencyInput control behaviing badly

[Mark]

I have identified a problem with the RadMaskedCurrencyInput controls handling of the backspace key.
I have set the following properties in code
 Mask = "";
 FormatString = "c";

 

The error scenario is
1. The control has the value "$0.00"
2. Place the cursor to the left of the period (between the '0' and the period).
3. Press the backspace key (The cursor ends up to the left of the left most '0')
4. Press the number '1' key to enter the value

 

Expected
The value in the control is "$1.00"

 

Actual
The value in the control is "$10.00"

 

At the moment this bug is preventing us from using the control. Is anyone able to provide a solution or workaround for this problem.

 

My client is running the latest version.

Hi Mark,

You can use the PreviewKeyDown event handler like so:

private void RadMaskedCurrencyInput_PreviewKeyDown(object sender, KeyEventArgs e)
     {
         var input = sender as RadMaskedCurrencyInput;
         if (input == null)
             return;

         if (e.Key == Key.Back && input.Value < 10 && input.SelectionStart == 2)
         {
             e.Handled = true;
         }
     }

Please let us know if this fits well in your scenario.
