How to perform drag-drop operation using multiple TreeNodeAdv's in WinForms TreeViewAdv?

Drag and drop operation

For the correct drag and drop operation with multiple nodes selection you would have to rewrite data sending and validating so that the entire TreeNodeAdv[ ] array would be considered and not just a single selected node.

Please refer to the steps outlined and the modified version of our TreeViewAdvDragDrop sample attached below:

1. In the ItemDrag event handler instead of sending single node, filter all correct nodes and pass an array of it.

2. In the DragOver event handler check the entire array of selected nodes instead of a single node.

3. Lastly, in the DragDrop event handler receive an array of nodes instead of a single node.
