    Dear Experts

    Am using RadTreeView Control. i am trying to add ,Edit and Delete a node dynamically.
    am able to add ,edit and delete the node in the treeview, but the problem am facing is

    1. sometimes when i select the node and click Add, its not showing in EditMode to enter the "Node Name".  (This case happens ocassionally, but when i kept the breakpoint and traverse the code, its working fine. thatsy i couldnt able to find out)
    2. Sometimes the Header text is gets disabled (i.e Text is Empty) when we traverse the node in the treeview
    3. i selected the node to add childnode below that. But the selected item says "null".
    4. i have implement add, Edit functionality in Lost_Focus Event, once a movement i added a node, and select any node in the treeview, The Lost_Focus event  is fires 2 to 3 times

     Thanks in Advance

    Hi Baskar,

    Thank you for contacting us.

    1. Could you please try setting the Edit mode in a Dispatcher.

    For 2,3 and 4: I am not sure how you traverse and select tree items. Also I don't think that LostFocus is the most appropriate event.

    Could you please send me a sample project reproducing the issues and demonstrating you scenario. This way I will be able to assist you faster and more appropriately.

    Thank you for your cooperation.
