Hi, I have tested the client side api of your FlyTreeView and it does not work as expected. The client side method node.setText(text); does not change node text if you change more than one node at a time... eg. foreach(node) { node.setText(...); } There should be a postback for all text nodes to be updated, wich is really anoying since it is a client side api I'm working with. Please find below the code that I used To reproduce, run the web site, Click flyTreeView_LoadCount Root(x) become Root(0) .. ok Root(x) does not change .. bug Sometime it works, sometimes it doesn't. Open Root(x) Click flyTreeView_LoadCount Category 1 (x) become Category 1 (0) .. ok Category 1 (x) does not change .. bug Sometime it works, sometimes it doesn't. This one never work. Open Category 1 (x) Click flyTreeView_LoadCount root (0) ok category 1 (0) ok category 2 (0) ok category 103 (0) ok category 204 (0) ok category 305 (0) ok category 406 (0) ok category 507 (0) ok category 608 (0) ok category 709 (0) ok category 810 (0) ok category 911 (0) ok category 1012 (0) ok category 1113 (0) ok category 1214 (0) ok category 1315 (0) ok category 1416 (x) bug category 1517 (x) bug category 1618 (x) bug category 1719 (x) bug category 1820 (x) bug category 1921 (x) bug category 2022 (x) bug category 2123 (x) bug category 2224 (x) bug and so on...

Yes, this was a bug.
A new control version that fixes it is coming this week.

Thanks.
