项目中最近用到了GridView导出Word的例子，但是无法导出成功。后来在下面地址找到了解决方案：http://www.cnblogs.com/jeff377/archive/2008/05/17/1201192.html。这里面是vb版的，我改成了C#版，具体的问题以及原因我就不赘述了，下面附上我的C#代码，希望对一些朋友有帮助：

模板：

public class ExportToExcel:WebPartPage

{

public override void VerifyRenderingInServerForm(Control control)

{

//base.VerifyRenderingInServerForm(control);

if (IsVerifyRender)

{

base.VerifyRenderingInServerForm(control);

}

}

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

}

private bool _IsVerifyRender=true;

public bool IsVerifyRender

{

get { return _IsVerifyRender; }

set { _IsVerifyRender = value; }

}

public override bool EnableEventValidation

{

get

{

if (IsVerifyRender)

{

return base.EnableEventValidation;

}

else

{

return false;

}

}

set

{

base.EnableEventValidation = value;

}

}

}

使用：

HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);

((ExportToExcel)gvwQuestion.Page).IsVerifyRender = false;

gvwQuestion.RenderControl(oHtmlTextWriter);

Export("application/ms-excel", QuestionExcelName, oStringWriter);
