Hi; I created an MDI application that contains report controls of same type and content in different views. It should be possible to use drag & drop to rearrange items within one report control but not to move/copy records from one report control to the other using drag & drop. Ho can I prevent this? ------------- Martin Product: Xtreme Toolkit v 22.1.0, new Projects v 24.0.0 Platform: Windows 10 v 22H2 (64bit) Language: VC++ 2022 |

Use app level to receive OnDragBegin notification and OnDragOver
Change dynamically m_dwDragDropFlags for all reports except originator to not allow to drop state using CXTPReportControl::EnableDragDrop funciton. Now you can drop you records only inside originator report control ------------- Mark Doubson, Ph.D. |

Hi; I did it al little bit different. Since I don't wnat to enumerate all active report control instances I decided to use a bool flag that is set when a drag operation starts and reset after a drop. In all other report control instances, this flag can't be set. Flag not set --> drop disabled. ------------- Martin Product: Xtreme Toolkit v 22.1.0, new Projects v 24.0.0 Platform: Windows 10 v 22H2 (64bit) Language: VC++ 2022 |

To prevent the drag and drop property of your XTPReport Control, Pass NULL value to the EnableDragDrop function.
This will disables the drag and drop operation.
rptMemberVar.EnableDragDrop(_T("Class"), NULL);
Override the OnBeginDrag, OnDrop method to customize your drag and drop operations.

as mentioned before, I solved it already! I don't want to disable drag&drop completely, I only wanted to disable drag&drop between different instances of the same report control class. ------------- Martin Product: Xtreme Toolkit v 22.1.0, new Projects v 24.0.0 Platform: Windows 10 v 22H2 (64bit) Language: VC++ 2022 |
