User control not updating
My Parent page is wrapped in an Update Panel and User Controls are also wrapped in Update Panels due to only needing partial postback on most of the user interaction with the control.Lets say I have an event on each User Control that bubbles back to the parent page called "On Enable Link".
At the left side you have a tree structure, and the right side is a list of icons.
The post covers dependency properties, and how to manage Data Context inheritance.
When building user interfaces you will often find yourself repeating the same UI patterns across your application.
When opening and closing the treelist you would not have the icon list to update.
When clicking a node on the treelist, the icon list should update.
