RegisterForEventValidation can only be called during Render();

By James Hippolite, in , posted: 21-Aug-2008 09:38

This error comes when you are exporting the GridView control from Visual Studio. To solve this error you have to turn the eventValidation off.  You can do this in the web.config file but if you do, the eventValidation will be turned off for all the pages.

<pages enableEventValidation ="false" ></pages>


Alternatively, you can do this in the Page directive which will turn off the validation for a single page.


<%@ Page Language="C#" EnableEventValidation = "false" AutoEventWireup="true"

 CodeFile="ExportGridView.aspx.cs" Inherits="ExportGridView" %>

Welcome to my technical blog. 

Here, I attempt to distill the Microsoft Certified Professional Developer knowledge I have accumulated since first qualifying MCP in 1996.  This blog started on 13 September 2007 as an off-shoot from my mixed up personal blog.  But it took a shot in the arm from Scott Hanselman's talk at TechEd New Zealand 08 "32 Ways To Make Your Blog Suck Less".
