    Every so often, and I don't know under what scenarios I can recreate this behaviour, the "loading..." text I have appearing under a node when it's clicked (data is loaded-on-demand) gets "stuck".

    By this I mean that the text appears and the node doesn't expand. If I click a different node and then back to the original one, it loads the data all over again, but this time expands correctly (however the "loading..." text remains).

    Is this a bug and if so is there a workaround?

    Thanks all,
    Daron

    Just to clarify, this is the 'NodeExpand' event and not the 'NodeClick' event.

    Hello Daron,

    This behavior is indeed odd. We have never experienced it before nor has it been reported by our customers. Could you reproduce it in our online demos? Have you noticed if there is some kind of pattern to reproduce the problem?

    The loading status message is hidden immediately once response is received from the server. If for some reason the response is slow the loading status message may stay a bit longer. Could it be the case?

    I've seen this problem also.  It is intermittent so difficult to troubleshoot.  I was thinking it may be related to debug mode, but I haven't run enough in release mode say.

    Hello Mark Griebling,

    If you manage to isolate the problem, we will greatly appreciate steps to reproduce it or a running sample.

    Thanks for your time and cooperation.

    I'm experiencing this problem too.  It only occurs for me when I'm using serverside callbacks for expanding and only when I double click the node to expand it.  If I click on the + icon to expand the node, the problem doesn't occur.  It's also intermittent for me.

    Thanks,
    Matt

    Hi Matt,

    Did you hook on the NodeClick event of the treeview? Could this be the problem  - that the treeview postbacks upon double click?

    Hi,

    The only event that I'm hooking is the Expand event so that I can load  new nodes when it is expanded.

    Thanks,
    Matt

    I see this issue too with load on demand from time to time.  My theory is its the problem I described here:

    http://www.telerik.com/community/forums/thread/b311D-bdkmgh.aspx

    which is the ViewState grows on each click and gets big enough to cause ajax timeouts.

    Hi christopher willis,

    I really put lots of efforts in my attempts to reproduce the problem locally, but to no avail. I hope that you will manage to isolate the problem in a small and running project and send the files to us to examine them locally.

    I can confirm this behaviour too.
    I even saw it in the treeview of your helppages the other day.
