ASP.NET- Instantiate a Web User Control in App_Code class

Question

Files:

Website\Controls\map.ascx

Website\App_Code\map.cs

I'd like to create a strongly typed instance of map.ascx in map.cs

Normally, in an aspx, you would add a <%Register... tag to be able to instantiate in codebehind. Is this possible in an app_code class? I'm using .NET 3.5/Visual Studio 2008

Thanks!

Answer 1

Normally, I'd do something like this (assuming your type is "Map" and that you have the appropriate "Inherits" declaration in your .ascx file):

Map map = (Map)LoadControl("~/Controls/map.ascx");

Answer 2

Is there a map.ascx.cs file in Website\Controls? If so, move it to App_Code. Note you may have to update the CodeFile attribute in the .ascx file to ~\App_Code\map.ascx.cs. Alternatively, since the control is a partial class, you could just create the code in ~\App_Code\map.cs as:

public partial class controls_Map : UserControl
{
    protected void Page_Load( object sender, EventArgs e )
    {
         ...code here....
    }
}

And remove all the methods from the map.ascx.cs file in the controls directory.
