Required validation for GridMaskedColumn

[Nishanth]

Hi,

I have a GridMaskedColumn in my RadGrid and in the edit mode, the Masked Textbox is supposed to take US phone number as input. I have added the following mask (###)###-#### to the GridMaskedColumn. But the problem is that its accepting space also. I want to display client side error/warning when the user does not enter all the 10 digits of the phone number and press on 'Update Button' so that the DB values are consistent. Is there any mask or any other way I can implement this client validation ?

Thanks,
Nishanth

Hello Nishanth,

You can use a CustomValidator to see if the entered value fulfills the requirements and then dynamically change the textbox style, as shown below:

<asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="RadMaskedTextBox1"
    ClientValidationFunction="validate" ErrorMessage="Error " EnableClientScript="true"
    Display="Dynamic" />
<telerik:RadMaskedTextBox ID="RadMaskedTextBox1" runat="server" Mask="(###)###-###" />
<script type="text/javascript">
    function validate(source, eventArgs) {
        var textbox = $find(source.controltovalidate)
        var val = textbox.get_value();
        alert(val.length);
        if (val.length < 9) {
            textbox.get_styles().EnabledStyle[1] += " riError";
            textbox.updateCssClass();
            arguments.IsValid = false;
        }
        else {
            textbox.get_styles().EnabledStyle[1] = textbox.get_styles().EnabledStyle[1].replace("riError", "");
            textbox.updateCssClass();
            arguments.IsValid = true;
        }
    }
