Is there a Hierarchy with the controls that can be linked to one-another?
The reason I ask is because I have a RadSplitter that contains 2 RadPanes separated by a RadSplitBar. The first RadPane (left) contains a RadTreeView control and when the user clicks a node in the tree I want to change the ContentURL of the second RadPane (right).
The problem occurs when I add a RadAjaxManager and in the first pane I select the RadTreeView as the control I want to initiate the callback. I then select the second RadPane as the receiver.
When the user clicks a node in the tree the following error pops up,
Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_ContentPlaceHolder_radPaneContentPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.
I was wondering if it was the hierarchy causing the problem as in the RadPane receiving the callback is one level above the RadTreeView initiating it in terms of the control hierarchy,
If it's not that then could someone please explain what the hell is going on...?
To get around the problem I even tried to setup the XJAXing programatically directly on the tree nodes themselves when I dynamically create them but that didn't seem to work at all and I've opened another thread on that topic (Configuring RadAjaxManager Programatically
One of these ways has to work. Am I doing something really stupid???
