How to persist TreeNodeAdv selection?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: February 29, 2016 |
Last Revised Date: February 29, 2016

In TreeViewAdv, Child Node selection will not be persist upon Expand/Collapse functionality. This Node selection can be maintained by handling its events named BeforeCollapse and AfterExpand.




This event will be raised before TreeNodeAdv collapse. In this event, selected node can be stored.




This event will be raised after TreeNodeAdv expands. In this event, stored node details can be used to persist the selected node.


The following code example demonstrates the same.
