Hi All,

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtUserName" Display="None" ErrorMessage="<%$ Resources:WebResources,Label_Text_UserName%><%$ Resources:WebResources,IsRequired%>" EnableClientScript="true" >

But this is not working out, please let me know the syntax if this is possible. I want to do it only on aspx not in code behind.

Thanks in advance.

Suresh Kadam.

 You can use a custom expression builder. There are some cutom expression builders available which you can make you of. Please refer to the following link
