    I am using a treeView with LoadonDemand using a webservice-method. And I want to do drag&drop.
    - When I drag a node and insert it into a node that has been already expanded it works perfect (I think after expanding a node once, it gets the ExpandMode = clientside).
    - When I drag a node and hover the targetNode, wait till it has expanded and then release the mouse button to complete the drag and drop process, it works (because the targetNode is expanded now).
    - When I drag a node onto a targetNode and release the mouse button before the targetNode has been expanded I get an script Error.

    Can someone help me out here?

    Are you using the ClientNodeDropping or some other event? ClientNodeDropping works well for me, so try that if you are using a different event such as ClientNodeDropped. If you are already using ClientNodeDropping, try a different event.

    Hi Jonas,

    I tested the scenario with our latest official release Q1 2009 and wasn't able to reproduce this issue. Which version of the controls you're using?

    the Telerik team

    HI support

    We are using version 2013.1.403.35 and I can reproduce the error, the javascript errors because the target node 'y' does not have a "get_element()" method, this is the javascript call 'y.get_element().appendChild(k)'
    y does however have a set_element() method.

    Has this been fixed in the latest release?

    As it is mentioned in the previous post of the thread we were not able to reproduce the issue so far. Would you please share the exact code and the steps that will help us observe it locally so we could be more helpful with further information.
