Hi all,I am currently experiencing a problem with the WinTree component.
I implemented Drag/Drop as described in the related Sample (WinTree DragDrop) and used the UltraTree_DropHightLight_DrawFilter_Class.cs which I modified a little to suit our needs.
So far everything works fine and pleasant.
Now when dealing with DragDrop functionality it is required to expand a node when the Drag hovers over it. So I implemented the following lines in the load event:
tree.AutoDragExpandDelay = 500;tree.Override.AllowAutoDragExpand = AllowAutoDragExpand.ExpandOnDragHover;
I have chosen the ExpandOnHover option because the nodes of a node are only populated when the node is expanded the first time.
I expected that the node is expanded after 500 ms firing the BeforeExpand event so that I can evaluate the childnodes and add them.Unfortunately this does not seem to happen. The node I hover above always stays closed.
What am I doing wrong here... any help is kindly appreciated.
