ASP.NET how to Render a control to HTML?

Question

I have any ASP.NET control. I want the HTML string how to do I get the HTML string of the control?

Answer 1

If your control is a web user control, this is how you can get to the HTML it emits from another page or handler:

public void GetHtmlFromMySweetControl(HttpContext context)
{
    HttpRequest httpRequest = context.Request;
    HttpResponse httpResponse = context.Response;

    string foo = httpRequest["foo"];

    Page pageHolder = new Page();
    string path = "~/usercontrols/MySweetControl.ascx";
    MySweetControl ctrl = (MySweetControl)pageHolder.LoadControl(path);
    ctrl.BindProducts(foo);
    pageHolder.Controls.Add(ctrl);

    StringWriter sw = new StringWriter();
    context.Server.Execute(pageHolder, sw, false);
    httpResponse.Write(sw.ToString());
}
