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html Response.Write(tw.ToString());
