Reordering Tree records via mouse dragging

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

   I have a tree setup in C# that displays the files system, similar to the Details view in Windows Explorer.

I want to be able to select a file that already exists in the tree, and drag it on top of a folder.  When hovering over a closed folder, I'd like that folder to automatically open.  When hovering over other files, I'd like the red >---< insert indicator to appear, just like it does for the OLE Drag/Drop.  When I release the mouse, I'd like the file to be moved from its old position in the tree to the position marked by the indicator.

How do I do this?  I've been experimenting with the DragDrop functionality but it appears to only be potentially possible when dragging a node from tree1 into treeN where N is not 1.

I'm doing the following:

            m_TreeControl.EnableDragDrop("TC:InternalDrag", XTPReportDragDrop.xtpReportAllowDrag | XTPReportDragDrop.xtpReportAllowDrop);
            m_TreeControl.BeginDrag += new AxXtremeReportControl._DReportControlEvents_BeginDragEventHandler(m_TreeControl_BeginDrag);
            m_TreeControl.DropRecords += new AxXtremeReportControl._DReportControlEvents_DropRecordsEventHandler(m_TreeControl_DropRecords);
            m_TreeControl.RecordsDropped += new AxXtremeReportControl._DReportControlEvents_RecordsDroppedEventHandler(m_TreeControl_RecordsDropped);
            m_TreeControl.AllowDrop = true;

Callbacks:

        void m_TreeControl_RecordsDropped(object sender, AxXtremeReportControl._DReportControlEvents_RecordsDroppedEvent e)
        {
            Debug.WriteLine("Records dropped");
        }

        void m_TreeControl_DropRecords(object sender, AxXtremeReportControl._DReportControlEvents_DropRecordsEvent e)
        {
            Debug.WriteLine("Drop Records");
        }

        void m_TreeControl_BeginDrag(object sender, AxXtremeReportControl._DReportControlEvents_BeginDragEvent e)
        {
            Debug.WriteLine("Begin drag");
        }

When I start dragging a node, my "Begin drag" message is printed correctly to the output window, but the mouse cursor shows that the source tree isn't a valid drop target.  Is there anyway to do what I want?
