MaskedTextBox using Enumeration parts delete not working as expected

[Chris]

Hi,

I am using the Maskedtextbox for user input of a mac address, I am using the following code which works fine.  It displays "00-00-00-00-00-00" on initial load and only accepts characters 0-9 and A-F

<telerik:RadMaskedTextBox RenderMode="Lightweight" ID="RadMaskedTextBox3" runat="server" <br>Mask="<0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F>-<0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F><br><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F>-<0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F>-<br><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F>-<0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F><br><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F>-<0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F><0|1|2|3|4|5|6|7|8|9|A|B|C|D|E|F>"><br></telerik:RadMaskedTextBox>

The issue arises when I press the backspace to delete, all that happens is the cursor moves back but does not reset the character back to the initial mask value which is what I would expect to happen.

How can I achieve this.

Hi Chris,

Try out to set these properties to make it work as you are expecting:

AllowEmptyEnumerations="true"
PromptChar="0"
