User control updatepanel not updating
NET Ajax components that allows you to get a partial update of your page on postback.
You can place all of your old non-AJAX components inside the update panel and they will behave as they were AJAX enabled.
The code will then bind the items using Data Bind() on the repeater.
Now you have a web page that updates panels individually and where the panels can talk to each other.
Furthermore, the tree list user control must know about the thumbnail list in order to update it, so the thumbnail list must expose a function that the tree list can call so the thumbnail list is updated.
When clicking a node on the treelist, the icon list should update.In real life, the updatepanel of the thumbnail list contains some sort of iterateable list (a repeater for example).The thumbnail list then contains a public function called “Bind Data Source” or “Update List” that takes some parameters of which items to show.In this post, I will show you how to load different user control in Update Panel from different menu item click.
Thumbnail List = thumbnail List; } When the tree list needs to update the thumbnail list it will call a function on the thumbnail list that will update the thumbnails.This code is individual depending on the implementation.
