GridView中创先争优 [英] gridview to excel

问题描述

在asp.net vs05.when我出口的GridView工作创先争优，比我得到下面的错误

RegisterForEventValidation只能在渲染（被称为）;

为什么我得到这个错误。如何解决呢？

 公共无效ToExcel（）
{
    字符串附件=附件;文件名= Employee.xls;
            Response.ClearContent（）;
            Response.AddHeader（内容处置，附件）;
            Response.ContentType =应用程序/ MS-Excel的;
            StringWriter的STW =新的StringWriter（）;
            HtmlTextWriter的htextw =新的HtmlTextWriter（STW）;
            gvSearch.RenderControl（htextw）;
            的Response.Write（stw.ToString（））;
            到Response.End（）;
}
 公共覆盖无效VerifyRenderingInServerForm（控制控制）
    {    }
 

解决方案

在aspx页面，更改以下为false：AllowPaging =FALSEAllowSorting =假，并删除每页=10

work on asp.net vs05.when i export gridview to excel than i get the below error

RegisterForEventValidation can only be called during Render();

why i get this error .How to solve it?

public void ToExcel()
{
    string attachment = "attachment; filename=Employee.xls";
            Response.ClearContent();
            Response.AddHeader("content-disposition", attachment);
            Response.ContentType = "application/ms-excel";
            StringWriter stw = new StringWriter();
            HtmlTextWriter htextw = new HtmlTextWriter(stw);
            gvSearch.RenderControl(htextw);
            Response.Write(stw.ToString());
            Response.End(); 
}


 public override void VerifyRenderingInServerForm(Control control)
    {

    }

解决方案

in aspx page, Change the following to false : AllowPaging="False" AllowSorting="False" and remove Pagesize="10".
