Hi support team,
Telerik TreeView is awesome, all my requirements are met. Great job!
But here I am stuck:
- I have a tree and the user can select multiple nodes.
- Initially, some nodes are expanded, so that all selected nodes are displayed. I do this with a datasource and with the OnNodeDataBound.
- All nodes can be expanded with TreeNodeExpandMode.WebService
All works fine but when I collapse a initially loaded node, and then expand it again, the number of child nodes doubles, each child node is contained twice. When I do this again, it is still contained twice (not tree times).
How does the control do the "identity". Is is not the RadTreeNode.Value?
One workaround is the set the ExpandMode of RadTreeNode to Server to all nodes that are initially expanded. But then the user can not collapse it (nothing happens when the user clicks -). Best regards, a good customer
