MaskedEditExtender and MaskedEditValidator

[paper67]

Hi, I have the following code :

<form id="form1" runat="server">
    <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" />
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
            <asp:TextBox ID="TextBox1" runat="server" Width="70px" ValidationGroup="ValGrp"/>
            <asp:MaskedEditExtender ID="TextBox1MaskedEditExt" runat="server" TargetControlID="TextBox1"
                Mask="99/99/9999" MaskType="Date" UserDateFormat="DayMonthYear" />
            <asp:MaskedEditValidator ID="TextBox1MaskedEditVal" runat="server" ControlExtender="TextBox1MaskedEditExt"  
                ControlToValidate="TextBox1" IsValidEmpty="False" EnableClientScript="False" ValidationGroup="ValGrp"
                EmptyValueMessage="\*" InvalidValueMessage="dd/mm/jjjj" /><br />
            <asp:Button ID="SubmitButton" runat="server" Text="Submit" ValidationGroup="ValGrp" />
        </ContentTemplate>    
    </asp:UpdatePanel>    
</form>

TextBox1 is a required date field. On submitting the code throws me a client exception saying : 'className' is null or not an object What is wrong here ?

Do you have any Javascript code too associated with the page? 'className' is a javascript attribute and the error sounds like client side. Check if you have assigned/missed any css.
