“/”应用程序中的服务器错误。

---

类型“GridView”的控件“gridView1”必须放在具有 runat=server 的窗体标记内。

行 194:            System.IO.StringWriter tw = new System.IO.StringWriter();
行 195:            HtmlTextWriter hw = new HtmlTextWriter(tw);
行 196:            ctrl.RenderControl(hw);
行 197:            HttpContext.Current.Response.Write(tw.ToString());
行 198:            HttpContext.Current.Response.End();

检查代码，gridView1确实有runat=server标记。此时加入如下代码：

public override void VerifyRenderingInServerForm(Control control) { }
