Iam getting this error while transferring data from gridview to excel, can any one suggest me the solution"RegisterForEventValidation can only be called during Render();"

推荐答案

试试这个，



设置 EventValidation 到页面为false，并在后面的代码中覆盖 VerifyRenderingInServerForm ，

Try this,

Set EventValidation to false for the page and also override VerifyRenderingInServerForm in code behind,

public override void VerifyRenderingInServerForm(Control control)
{

}

i之前也遇到过同样的问题以下更改我的问题解决了。

请检查

i also faced with the same problem before and finally with the following changes my problem solved.
please check

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Records.aspx.cs" Inherits="Records" 
MasterPageFile="~/Master.master"  EnableEventValidation="false" %>

public override void VerifyRenderingInServerForm(Control control)
    {
        /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
           server control at run time. */
    }

嘿只是设置了viewstate false



//关闭视图状态

this.EnableViewState = False;

//从Content-Type标题中删除字符集

Response.Charset = String。空;



和

EnableEventValidation =false

hey just set viewstate false

//Turn off the view state
this.EnableViewState = False;
//Remove the charset from the Content-Type header
Response.Charset = String.Empty;

and
EnableEventValidation="false"
