 Topic: Drag&Drop to foreign windowsPosted: 26 June 2009 at 2:05pm |

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
