Asp.net Chart doesn't work in Page_Load when using LoadControl + UserControl

I have a UserControl which contains an asp.net Chart. If I reference the user control statically in the page, the chart displays, i.e.:

<uc:UserControl1 id="UserControl1" runat="server" />

However, if I load the user control from the codebehind in the Page_Load event, the Chart does not display:

Panel1.Controls.Add(this.LoadControl("UserControl1.ascx"));

I have other controls in the user control such as a GridView, and both of the above methods work for those controls. The only control that isn't working is the asp.net Chart control.

Any ideas?

When you instantiate dynamically created user controls in the code behind, you still have to set the reference is the aspx page.

<%@ Reference Control="UserControl.ascx" %>
