I'm trying to drag a textbox onto the design screen. I'm getting an error message. It says...
Error Rendering Control - TextBox1
An unhandled exception has occured
RegisterForEventValidation can only be called during Render();
I haven't changed any code, but I'll add it anyway. Thanks in advance!
<%@ Page Language="VB" %> <script runat="server"> ' Insert page code here ' </script> <html> <head> </head> <body> <form runat="server"> <asp:TextBox id="TextBox1" runat="server"></asp:TextBox> <!-- Insert content here --> </form> </body> </html>
