我整个上午一直在尝试这个,没有结果.我似乎无法弄清楚我做错了什么.我已经检查了两个链接(在许多其他无用的链接中)并且尚未解决我的问题.这是一个WebUserControl ......
收到以下错误:控件'TextBox'类型的'HeadContent_CareersViewPosting_txtFirstName'必须放在带有runat = server的表单标记内.
已经尝试过这里的建议,这里和这里都没有结果.仍然收到完全相同的消息.一些新的建议将不胜感激!

现在我正在尝试使用LoadControl来加载以前生成的Control并吐出它的HTML,但它给了我这个:
必须将带有'TextBox'类型的控件放在带有runat = server的表单标记内.
我实际上并没有将控件添加到页面中,我只是想抓取它的HTML.有任何想法吗？
这是我正在玩的一些代码:
TextWriter myTextWriter = new StringWriter();
HtmlTextWriter myWriter = new HtmlTextWriter(myTextWriter);
UserControl myControl = (UserControl)LoadControl("newUserControl.ascx");
myControl.RenderControl(myWriter);
return myTextWriter.ToString();
我的DataGridVew有问题
我正在尝试从我的数据库导出数据到excel fie
这是一个小页面,其中只有数据网格视图和按钮导出如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

<asp:BoundField …TextWriter tr = new StringWriter();
HtmlTextWriter writer = new HtmlTextWriter(tr);
HtmlForm form = new HtmlForm();
form.Controls.Add(divQueryDescription);
divQueryDescription.RenderControl(writer);
<div runat="server" id="divQueryDescription">
<asp:GridView runat="server" id="grv"></asp:GridView>
</div>
我的GridView在DIV中,我将DIV添加到HtmlForm中,以便我可以将其渲染为字符串.但是我收到以下错误: -
Gridview'grv'必须放在带有runat = server的表单标签内,尽管我的Gridview已经在表单中,因为我将DIV添加到表单中.
如何将此DIV渲染为字符串？
我使用波纹管代码导出gridview数据excel但问题是整个页面导出到excel.我只想要gridview数据而不是整页导出.怎么能解决这个问题？
HtmlForm form = new HtmlForm();
Response.Clear();
Response.Buffer = true;
string filename = "GridViewExport_" + DateTime.Now.ToString() + ".xls";
Response.AddHeader("content-disposition", "attachment;filename=" + filename);
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
gdvInBox.AllowPaging = false;
gdvInBox.DataBind();
form.Controls.Add(gdvInBox);
this.Controls.Add(form);
form.RenderControl(hw);
//style to format numbers to string
string style = @"<style> .textmode { mso-number-format:\@; } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
提前致谢.
我是.net的新手,我使用以下代码从gridview转移到excel:
protected void toexcelbutton_Click(object sender, EventArgs e)
{
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "attendancedatereport.xls"));
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.AllowSorting = false;
GridView1.DataBind();
HtmlForm htmfrm = new HtmlForm();
GridView1.Parent.Controls.Add(htmfrm);
htmfrm.Attributes["runat"] = "server";
htmfrm.Controls.Add(GridView1);
htmfrm.RenderControl(htw);
Response.Write(sw.ToString());
HttpContext.Current.ApplicationInstance.CompleteRequest();
}
当我运行此代码时,我得到一个例外:
mscorlib.dll中发生了'System.Threading.ThreadAbortException'类型的第一次机会异常.
但是,当我在另一个页面中为另一个gridview运行相同的代码时,它运行得很好.我尝试添加
EnableEventValidation="false"
到aspx页面,和
<pre lang="cs">public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}</pre>
到aspx.cs页面,
我尝试清除临时文件,仍然我得到相同的错误,超过5小时我试过,没有什么工作.
然后我尝试选择Debug - > Exceptions菜单项,并在出现的对话框中选中"Common Language …
