Communicate between UpdatePanels ASP.Net -

I have placed a paste view in an update panel & lt; UpdatePanel id = "UP1" & gt; & Lt; ContentTemplate & gt; & Lt; TreeView / & gt; & Lt; / ContentTemplate & gt; & Lt; / UpdatePanel & gt; & Lt; MultiView & gt; & Lt; UpdatePanel id = "UP2" & gt; & Lt; View1 / & gt; & Lt; / UpdatePanel & gt;

Now I want to know how can I ensure when I display a related view of any node in the tree view

If you have a code for the click event of the previewview, then UP2.Update () will have to call Codebehind, another way to come near it. Remember, UP2 must set its reader mode to be conditional to work. Hope it helps
