CompositeControl in ASP.NET 2.0, C#. I have the following code in the
CreateChildControls() method that build the control's child control
collection:
for (int i = 0; i < _menus.Count; i++)
this.Controls.Add(_menus[i]);
foreach (FloatingMenu menu in _menus)
{
Label lbl = new Label();
lbl.ID = string.Concat("GroupQ", menu.ID);
lbl.CssClass = "menuItemGroupHeader";
lbl.Text = menu.GroupName;
this.Controls.Add(lbl);
HoverMenuExtender extender = new HoverMenuExtender();
extender.ID = string.Concat("ExtenderQ", menu.ID);
extender.TargetControlID = lbl.ID;
extender.PopupControlID = menu.ID;
extender.PopupPosition = HoverMenuPopupPosition.Bottom;
this.Controls.Add(extender);
}
The amazing thing is here, that the Label control and the HoverMenuExtender
AJAX Toolkit control both get added just fine, however I added a watch on
this.Controls.Count for the line where I add my FloatingMenu control
collection, "_menus", and after each call to "this.Controls.Add(_menus[i]);"
the Count is 0, however after I add the label it's 1 and the extender it's
2.
I'm stumped.
Thanks,
ChadWhat is the value of _menus.Count before the for loop

_menus.Count is 2 before the loop. And the second, foreach loop adds 2
Labels and 2 HoverMenuExtenders as it should. I tried the first loop with a
foreach initially, but remembering SyncRoot issues and thought perhaps the
enumerator was breaking the Add operation, I changed it to the for loop to
no avail.

Does anyone have any clue why this would happen? I'm still banging my head
against a wall trying to figure this out.
