I have a dropdown extender attached to a label on a page.  When the lable is clicked I load an infragistics tree control into the panel the dropdown extender controls.  The panel displays as it should the tree displays as it should - but when I click on any of the node expand items the panel hides itself - I click on the lable again and the panel displays - with the node I just click expanded. 

I set autopost back on the node to false - but it still happening.. what I want is to have the panel and tree control stay visible unless I click on a node item.  I'm not sure if this is a tree control thing or a dropdown panel thing - any suggestions?!

 Update - I tried wrapping the label - exenter and the panel / control in an update panel but still no luck..

looks like a post back is happening as I can catch the node expand in a server side event  - is there as way I can force the dropdown extender to stay visible via code?

 Thanks!
