mimimum / set length reqs for MaskedTextbox

[Coty]

Looking to use the phone mask (###) ###-#### and set a valid values to be length of 7 or 10.

I can use a regular expression validator on an ASP.NET control, but it does not work with the Masked TextBox.

Any Ideas?

Thanks,

I figured out a way to do this in case anyone else comes along.  I used a custom validator with a ClientValidationFunction Set.
Here is my code:

HTML

 

 

 

<rad:RadMaskedTextBox ID="txtTollFree" Mask="(###)###-####"
                                onblur="javascript:UpdatePreview('Phone');" Width="73px"
                                runat="server" BackColor="#CCCCCC" Enabled="False">
                            </rad:RadMaskedTextBox>
                            <asp:CustomValidator ID="CustomValidator1" runat="server"
                                ClientValidationFunction="CheckLength"
                                ErrorMessage="Phone\Fax numbers must be 7 or 9 digits"
                                ControlToValidate="txtTollFree">*</asp:CustomValidator>

Javascript

 

 

function CheckLength(source, args)
{
    if (args.Value.length == 10 || args.Value.length == 13)
    {
        args.IsValid = true;
    }else{
        args.IsValid = false;
    }
}

 

 

Only hitch was I had to add 3 to the lengths I was checking for because of the mask ()- characters.

Thanks,
