Postback is done correctly and the event on the server is also fired correctly. but then it looses its state. The Tree is inside an AJAX Panel but this doesn't get updated at this stage. After the postback some other AJAX Panels are updated but not this one.<br /></p> <p> </p> <p>It's a LoadOnDemand Tree.  <br /></p> <p> </p> <p>Any ideas? <br /></p> <p> </p> <p>Thank you. <br /></p>
