Question

I am trying to add dynamically a user control I created to an aspx page after it is loaded.
I tried sending an ajax request to a handler that used RenderControl function and sent back the control’s html. I appended it to the DOM using javascript.

The problem is that some of the controls must go through their Page_Load function and that doesn’t happen when using RenderControl function.

Does anyone have any idea how can I do that?

try this:

System.Web.UI.Page page = new System.Web.UI.Page();
CustomUserControl userControl = page.LoadControl("~/control.ascx") as CustomUserControl;
if (userControl == null)
{
//error
}

userControl.ArticleId = id;
//call any other properties or methods you need

page.Controls.Add(userControl);
System.IO.StringWriter sw = new System.IO.StringWriter();
HttpContext.Current.Server.Execute(page, sw, false);
responseString = sw.ToString();

hope this will help!
