    I don't see this documented anywhere, so maybe this should be filed under "wishes", but did I miss a way to define a required digit in a mask?

    I'd like to define a mask for, say, zip code that REQUIRES the first 5 digits, with the others being optional.

    If not, consider it a request for the future. :)

    Hello Chris,

    You can use CustomValidator control. The following code example demonstrates how to use the ClientValidationFunction property to specify the name of the function that performs client-side validation of the RadMaskedTextBox:

                <script type="text/javascript"
                   function ClientValidate(source, clientside_arguments) 
                        var input = $find("<%= RadMaskedTextBox1.ClientID %>"); 
                        var textBoxValue = input.get_textBoxValue();. 
                        if (is first 5 digits) 
                            clientside_arguments.IsValid = true
                            clientside_arguments.IsValid = false
                <asp:CustomValidator ClientValidationFunction="ClientValidate" ControlToValidate="RadMaskedTextBox1" ID="CustomValidator1" runat="server" 
                <asp:Button ID="Button1" runat="server" Text="Button" />

    I realize this is a very old link... but if anyone finds it, I was able to do this using double zero's in my range... <00..10> force the input of 00, 01, 02, 03, 04, 05, 06, 07... etc.... which is exactly what I wanted here. Just thought I'd share. ;)
