Hi,

I am having the following issue. In my user control i have a RadDatePicker, RadChart & a RadTreeView. Now these are all wrapped in a RadAjaxPanel. All works fine until i drill into the chart. Once i do that i find that the RadTreeView is no longer working (i.e. can't open or collapse the branches). This code was all working in the Q1 2009 release UNTIL i got the LATEST Q1 2009 release. I have replicated the code from my user control into a simple aspx page. Please see below.

Anyone got any ideas or experiencing the same problem??
