PODynamically Loading a UserControl with LoadControl Method (Type, object[])
text
Body
copied!<p>I'm trying to return the html representation of a user/server control through a page method. It works when I call the overload which takes the virtual path to the user control, but not when I try to call the overload which takes a type. The sample code is below. Any suggestions?</p> <pre><code>[WebMethod] public static string LoadAlternates(string productId, string pnlId) { object[] parameters = new object[] { pnlId, productId }; return ControlAsString(typeof(PopupControl), parameters); } private static string ControlAsString(Type controlType, object[] parameters) { Page page = new Page(); UserControl controlToLoad; /* *calling load control with the type results in the *stringwriter returning an empty string */ controlToLoad = page.LoadControl(controlType, parameters) as UserControl; /* *However, calling LoadControl with the following overload *gives the correct result, ie the string rep. of the control. */ controlToLoad = page.LoadControl(@"~/RepeaterSamples/PopupControl.ascx") as UserControl; //some more code, then this... page.Controls.Add(controlToLoad); StringWriter sw = new StringWriter(); HttpContext.Current.Server.Execute(page, sw, false); return sw.ToString(); } </code></pre> <p>Any ideas why this StringWriter would return an empty string? I should point out that all the "page" lifecycle execute correctly irrespective of the method chosen to call LoadControl.</p> <p>Wanted to add - I <em>have</em> to use the <code>LoadControl(Type, object[])</code> overload. :-(</p>
