I am trying to do Drag&Drop as show in the Telerik documentation (see https://docs.telerik.com/devtools/winforms/controls/gridview/rows/drag-and-drop).
I tried to implement it in three different ways:
1) after reading the doc, I downloaded the code and build it with VS2022. This code uses .Net Framework 4.6.1 and works exactly as expected.
2) Then, I tried to add it to my current project using .Net 6 and the current Telerik Library. I did it both in the form where it should be used and in a dedicated form with the exact code provided. In both cases, I have the 'strange' behavior that the drag works but as soon as the grabed row is movingout of its origin, a "no entry" sign is shown both in some area of the initial grid view and everywhere in the destination one (see picture).
3 Then I tried to do it in a brand new .Net 6 project to dismiss a potential setup in my project. In this third one evrything compile and run nicely, BUT there is absolutely no drag and drop behavior.
I attached this last project, but it is really exactly the downloaded code.
So can someone explain what is wrong in this code or my way to use it ?
In addition to my previous message, I did a final trial. I took the code provided on Github (https://github.com/telerik/winforms-sdk/tree/master/GridView/DragAndDropBetweenGrids), opened it in VS2022, checked that it was nicely working (as previously said) and then upgraded the Telerik UI for Winforms version. The ruslt was exactly like in my point 3 : it compiles and run but drag drop is not anymore visible nor working.
