Problem with drag/drop

I have AfxOleInit in app InitInstance, I have called in my docview::initinstance:

wndReport.EnableDragDrop( _T("BuildITTask:v2"), xtpReportAllowDrag | xtpReportAllowDrop );

When I drag I get the standard cursor with a little box under it ... but I do not get the red line between the rows.

Any reason for this? Could anyone help.

Found it, I had to clear the group and sort by order arrays (even though they are disabled) when I initialise my view. Now I have drag/drop, my messages are being received and the red drop marker is being drawn. Hurrah!

For anyone else, if you load/save state, call these two after adding columns and loading the state if you dont actually want groupby and column sorting (as you cant have drag/drop with column sort/grouping):

CXTPReportControl &wndReport = GetReportCtrl(); wndReport.GetColumns()->GetGroupsOrder()->Clear(); wndReport.GetColumns()->GetSortOrder()->Clear();
