的GridView必须被添加到一个表格标签用于呈现 [英] GridView must be added to a form tag for rendering

问题描述

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是一个DIV里面，我补充一点，DIV到的HtmlForm，这样我可以把它呈现为一个字符串。但我得到以下错误： -

My GridView is inside a DIV and I add that DIV to an HtmlForm, so that I can render it to a string. But I get the following error:-

GridView的'GRV'必须放在与RUNAT =服务器的形式标记中，虽然我的GridView已经是一个形式里面，因为我加了我的DIV的形式。

Gridview 'grv' must be placed inside a form tag with runat=server, although my Gridview is already inside a form because I added my DIV to the form.

我怎样才能使这个DIV为一个字符串？

How can I render this DIV to a string ?
