    Scenario: I have added nodes in the treeview by using the designer and wanted to keep the nodes in expanded mode once it makes a postback after the node is clicke. Could you please help me how well i could achieve the desire stuff.

    Explanation: When the treeview makes a postback with nodeclick event the nodes in the treeview is collapsing. Please help me in keeping them expanded.

    Hi Ali Akbar,

    I tried the scenario and RadTreeView (RadControls Version 2009, 3, 1103, 35) keeps the expanded state even after postback. Probably the following code library will be of help if you are using old version of RadControls.
    Save the expanded state of the TreeNodes when the treeview is being bound upon each postback
