Hi Richard,
This is also possible. Here's the updated version:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Init(object sender, EventArgs e)
{
for (int i = 0; i < 5; i++)
{
this.Accordion1.Panes.Add(new MyPane());
}
}
}
public class MyPane : AccordionPane
{
static Random random=new Random();
public MyPane()
{
this.Init += new EventHandler(MyPane_Init);
}
void MyPane_Init(object sender, EventArgs e)
{
int test = random.Next(0, 100);
ContentUserControl cuc =
this.Page.LoadControl("ContentUserControl.ascx") as ContentUserControl;
cuc.TestText = "ContentTest_" + test;
HeaderUserControl huc =
this.Page.LoadControl("HeaderUserControl.ascx") as HeaderUserControl;
huc.TestHeader = "HeaderTest_" + test;
this.Header = new MyHeaderTemplate() { UserControl = huc };
this.Content = new MyContentTemplate() { UserControl = cuc };
}
}
The key point is to use the Control.Page property. Another note is, we
generally do this in the Init event handler. If we get the Page property in
the constructor method the property is null since no value has been
assigned to it. If we do this in a later event than the Init some page life
cycle puzzle would probably happen.
Please have a try and let me know if it works.

Allen Chen

| Thanks Allen,
|
| you have understood my question correctly, although I was hoping that I
| could load the user control in MyPane and encapsulate header and footer
| totally within MyPane so that within the aspx I could just have
| this.Accordion1.Panes.Add(new MyPane()); rather than the aspx having to
| know what is needed to fill the pane.
|
| I assume however if there was some equivalent LoadControl method for the
| MyPane custom control that you would have described that as a solution.
This
| solution works fine, though is not quite as neat as I would have liked.
