    Hi EveryOne,

    I have a question about the TreeView ExpandMode.
    Currently, I set childNode.ExpandMode = TreeNodeExpandMode.WebService;

    After Initialize the tree, and  I click button. In the button event, I set some nodes of the tree expanded = true
    My question is that Will these nodes are expanded or not?

    Does anybody know about that?

    Actually, I Would like to do the following thing. After I click one node, I get RadWindows. The tree is needed to keep the previous states(expanded, selected) and update its image after closing the popup window.

    is it possible? 

    Thank you.

    Please find in this help article some special cases about expanding the RadTreeView nodes with different expand modes set.

    Regarding your second question - as far as I understand you want to save the node expanded state after post-back. If yes - please review the following help resource showing how you can accomplish it.
