1、自定义加载用户控件
ceshi.aspx页面
<html><body><div id="divControls" runat="server"></div></body></html>
ceshi.aspx.cs页面
System.Web.UI.UserControl newUC = (System.Web.UI.UserControl)Page.LoadControl("ceshi.ascx");divControls.Controls.Add(newUC);
2、把用户控件转换为html字符串
Page page = new Page();//这里新建了一个page对像，不是当前的page对像System.Web.UI.UserControl control = (System.Web.UI.UserControl)page.LoadControl("ceshi.ascx");page.Controls.Add(control);//在新建的page对像中加载进去System.IO.StringWriter tw = new System.IO.StringWriter();HtmlTextWriter wt = new HtmlTextWriter(tw);page.RenderControl(wt);//在新建的page对像 输出htmlResponse.Write(tw.ToString());
