Hey all, I get this error upon testing my webpage:

Now, everything worked fine, right up until I added this line of code:

<asp:RequiredFieldValidator Class="error" ID="rfv_name" ControlToValidate="txt_name" Text="Please Enter a Value" runat="server" />

Anyone know what it is? I don't have an jQuery elements in my code, and am using VS 2013 if that helps.

Here is the full Panel of code:

<asp:Panel ID="pnl_bugform" runat="server">
        <form method="post" runat="server">
            <asp:Label ID="lbl_name" Text="Your Name" runat="server" />
            <asp:TextBox ID="txt_name" width="250px" runat="server" />
            <asp:RequiredFieldValidator Class="error" ID="rfv_name" ControlToValidate="txt_name" Text="Please Enter a Value" runat="server" />
            <br /><br />
            <asp:Button ID="btn_submit" runat="server" Text="Submit" onclick="btn_submit_Click" />
        </form>
    </asp:Panel>

Try adding the following to the root (Configuration) node of your web.config file:

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

Here's the MSDN Article (it's the last entry), and a few more from CodePlex and StackOverflow. They'll tell you to do the same thing, but contain more info.

That worked! Of all the forms I've built, I have never had to do that.... Maybe something changed in VS 2013? First asp project I've done in 2013 and first time this has happened.... Well it's working now!

Which version of .NET are you targetting? From the limited amount of research I did, it seems to be related to targeting older versions of the framework from projects in the newer Visual Studios, perhaps due to a lack of support for HTML5 features in older versions of the framework. Anyway, glad it's working for you now!

Nope targeting 4.5.... I have been having weird issues with 2013 all day though. Now it crashes anytime you type a character after a #. Makes changing my .css inside VS impossible.

  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>

Well, scratch that then. But I'll keep an eye out for this next time a build a web app.
