Required Digit in Mask

[Chris T.]

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:

        <div>
            <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;
                    }
                    else
                    {
                        clientside_arguments.IsValid = false;
                    }
               }
            </script>
            <telerik:RadMaskedTextBox
                ID="RadMaskedTextBox1"
                runat="server"
                Mask="#####-####">
            </telerik:RadMaskedTextBox>

            <asp:CustomValidator ClientValidationFunction="ClientValidate" ControlToValidate="RadMaskedTextBox1" ID="CustomValidator1" runat="server"
                ErrorMessage="CustomValidator">
            </asp:CustomValidator>

            <asp:Button ID="Button1" runat="server" Text="Button" />

        </div>

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. ;)
