Hi,

I enabled Drag&Drop in my CXTPReportControl derived class with the following command:

EnableDragDrop(_T("MyDragFromatName"), xtpReportAllowDrag | xtpReportAllowDrop);

...and I have some text and markup coloumns in this control.

Now when I drag a row outside my window and place it in a e.g Visual Studio text file, the text of the row including the markup is moved to this text file.
These rows are completly removed from my Report Control - but drop cursor still says "Drop not allowecd".

How can I prevent moving this rows to outside my control?

Thanks!

You need to overwirte function virtual void OnDragLeave(CWnd* pWnd)

Now there is not restriction here - you can add in (e.g. in your derived class):

class CXTPReportControl::CReportDropTarget -

virtual void OnDragLeave(CWnd* pWnd) {

CXTPReportControl* pReport = DYNAMIC_DOWNCAST(CXTPReportControl, pWnd);

if (pReport) pReport->OnDragOver(NULL, 0, CPoint(-1, -1), 1);

}

I suppose you can do this too:

m_wndReport.EnableDragDrop(_T("My_Own_Records"), xtpReportAllowDragCopy);

Works for me!

This flag (xtpReportAllowDragCopy) essentially make OPPOSITE effect - it ALLOW to drop to foreign window - I succeded to drop selected range from modified (with this code) Pane app to static non-modified one (which use standard xtpReportAllowDrag | xtpReportAllowDrop

Even with user-defined "My_Own_Records"?

if you use unique Clipboard format name FIXED for your app - you can only drag and drop between same app (but in different instances)

if you use run-time random name - only drag and drop in same running instance
