Required Field Validator Problem

Question

Hi

 

I am using RequiredFieldValidator in my code. 

 

<asp:TextBox ID="txtMobileNo" Width="321px" BorderColor="Black" runat="server"></asp:TextBox>

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="txtMobileNo" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>

 

but i got following error at runtime

 

WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive).

 

I am also put following code in webconfig file

 <appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None"/> </appSettings>

but not change.
