All of my controls derive directly from the MFC classes:-

Both of my tree controls derive from CTreeCtrl and both of my list controls derive from CListCtrl.

Hi,
If you use CXTTreeCtrl  try to change it to standard CTreeCtrl.

I don't know if this is an MFC problem, or a ToolkitPro problem...

I'm trying to get drag and drop working between CXTPDockingPanes in my application. I have 4 panes:

Pane 1 has a CXTPTabControl with a CTreeCtrl derived class on each tab
Pane 2 has a CXTPTabControl with a CListCtrl derived class on each tab
Pane 3 contains just a CTreeCtrl derived class
Pane 4 containg just a CListCtrl derived class

I have added ON_NOTIFY_REFLECT(TVN_BEGINDRAG, OnTvnBegindrag) to my two CTreeView classes and ON_NOTIFY_REFLECT(LVN_BEGINDRAG, OnLvnBegindrag) to my two CListView classes, but only pane 1, 2 and 4 respond! The pane containing my CTreeCtrl class doesn't hit the OnLvnBeginDrag method.

Question 1 - any idea why the pane containing just a CTreeCtrl class doesn't respond to a drag?

In the 3 classes where the drag works, I create a COleDataSource and populate it, then call DROPEFFECT dropeffect = OleDataSource.DoDragDrop(DROPEFFECT_MOVE, NULL);.  I have added OnDragEnter, OnDragOver and OnDrop methods on my 4 CTreeCtrl and CListCtrl classes, but none of them are hit.

Question 2 - any idea why none of the pane contents are hitting their OnDragEnter, OnDragOver and OnDrop methods?
