Hi! I've implemented the basics of drag and drop by implementing the following functions: ON_NOTIFY(XTP_NM_REPORT_BEGINDRAG, XTP_ID_REPORT_CONTROL, OnReportBeginDrag) ON_NOTIFY(XTP_NM_REPORT_DRAGDROP_COMPLETED, XTP_ID_REPORT_CONTROL, OnReportDrop) ON_NOTIFY(XTP_NM_REPORT_DRAGOVER, XTP_ID_REPORT_CONTROL, OnReportDragOver) Now I need to move a bit further: 1) I can't seem to find any built-in functionality for scrolling while dragging (vertically), so I assume I'll need to implement this myself, right? Would I better off using the mousemove in my view (where the report is located)? How can I programatically scroll the report up/down a number of rows? 2) I've got 2 view with 2 separate reports, they're created the same and have very similar code, but in one when I drag I get a red marker drawn in the other I get a blue one - I couldn't find what the blue one is. Can you please give me a clue  Thanks! ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

1. We are working on Core support for AutoScrolling - will be in 13.2.2 soon
2. Blue (GetPaintManager()->m_clrHyper) marker line appears ONLY in debug mode in CXTPReportControl::DrawExtDropMarker function - in release mode red line (GetPaintManager()->m_clrHotDivider) used, CXTPReportControl::DrawDropMarker(CDC* pDC) use only red color.
Now analyze your code why different functions used ------------- Mark Doubson, Ph.D. |

Thanks, It seems that the flag m_bSortedDragDrop was set to true in one and false in another, not sure why though. ------------- // W7 64 Ultimate SP1 // VS 2008 // CodeJock 16.2.3 (MFC) |

Also, it seems that when I get a XTP_NM_REPORT_BEGINDRAG message, the dragged records list is empty for some reason. Currently, I store a pointed to it in my app, because I need to know about it - I have to check that they're not dropped on their own children.

please use 13.2.2 - https://forum.codejock.com/uploads/DemoVersion/ReportControlMFCUpdated.rar - https://forum.codejock.com/uploads/DemoVersion/ReportControlMFCUpdated.rar as DD still in process of modifications (e.g. to support custom clipboard types) ------------- Mark Doubson, Ph.D. |

Yes- and you need to get source updates from same permanent link

because DD support still in progress - e.g. we want to have RightButton Drag'nDrop - like Windows Explorer - with app-level context menu ------------- Mark Doubson, Ph.D. |

Ok, thanks. But when do you plan to release the next update? I can wait a little bit if it's not too far away ;)
