Question

I am trying to dynamically load a user control in an asp.web site. However due to how asp.net websites projects are setup (I think), I am not able to access reach the type definition of the user control.

I get a message saying that my class HE_ContentTop_WebControl1 is: he type or namespace name ‘HE_ContentTop_WebControl1’ could not be found (are you missing a using directive or an assembly reference?)

Any idea how this could be made to work ? I have attempted using namespace but it seems to me that asp.net websites are not designed to work with namespaces by default. I would be interested in a non namespace approach.

TIA

public partial class HE_Default :
     System.Web.UI.Page   {  

    protected void Page_Load(object sender, EventArgs e)  
    {  
       var control = (HE_ContentTop_WebControl1)Page.LoadControl("~/ContentTop/WebControl1.ascx");         
    }
}

Assuming the control exists in the same assembly as your web project, you need to add a reference directive in your .aspx file,

e.g:

<%@ Reference Control="~/Controls/WebControl1.ascx">

Keep in mind it often takes a few minutes (or sometimes a build) for IntelliSense to pick this up.
