Is it possible to add a UserControl to a Composite control?

Question

I'm trying to build a CompositeControl that's flexible. Depending on some of it's parameters, I would like my CompositeControl to load different user controls in it's CreateChildControls method. The exact UserControls aren't know at design time.

Just as a quick example, I tried with a "hard coded" UserControl and it failed:

protected override void CreateChildControls() { Control UserControlControl = Page.LoadControl(typeof(MyUserControl), null); Controls.Add(UserControlControl); Label RegularControl = new Label(); RegularControl.Text = "This gets displayed"; Controls.Add(RegularControl); }

Is it possible to attain what I'm looking for?

Thanks

What was the failure message?

Try the following:

protected override void CreateChildControls() { Control UserControlControl = Page.LoadControl("~/path/to/control.ascx"); Controls.Add(UserControlControl); }

Yup, that did it. This will do but I'd still be curious in learning how to use the other overload method with the type as argument.
