Hello,
i'm using infragistics 9.2 and there is a problem with the event DragDrop of UltraListView. Basically it just wont fire. All the other event of drag and drog like DragEnter,DragLeave and DragOver fire correctly.
Probabily this is a bug:(
UltraListView has no intrinsic support for drag and drop, so the bug has to be in the client implementation. There is a sample that is included with the SDK, 'WinListView DragDrop', which demonstrates how to correctly implement the dragging of items from one control to another. If you have a simple sample that demonstrates the probelm you are having you can attach it to this thread and we will try to help.
