Multiselect and drag-and-drop

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello All
I have the problem in CXTTreeCtrl. I want to implement the drag-and-drop for multiply selected items. The drag-and-drop for single item works fine, but when I call CXTTreeCtrl::EnableMultiSelect function, I begin receive OnBeginDrag notification even when I simple click on some item and then release the mouse button.
In order to demonstrate this behaviour I wrote the little application, attached to this question. Decommenting the "m_Tree.EnableMultiSelection()" line in CDemoDlg::OnInitDialog function starts all the problems.
I order to solve this problem I wrote my own handler for OnLButtonDown message, (so drag-and-drop of multiply items is working), but, as result, I don't receive OnLButtonUp message after simple click. This causes me additional problems.
I use XTreemTookit 1.9.2.2.
All ideas will be accepted with great thanks
Best regards
