I am new to this grid control and I'm working to create a custom D&D function. This grid will have "boxes" of data, and when I select the Header of one of these boxes, I should be able to drag and drop the box to another location on the grid. Currently i'm able to do this using the mouse events, but I would like to use the DragOver and DragDrop events so the user is aware he is dragging.
I currently have DragOver and DragDrop implemented, but when I drag the cell to another location I keep getting the "Not Allowed" cursor when I pause the mouse, when the mouse is in motion it shows the "Move" cursor.
The drag movement will not be the normal OLE move as this grid is refreshed off a custom data source. I receive this exception when I let go out the mouse during the drag. Perhaps a default D&D functionality of the grid is interfering with my custom events ? Any help is appreciated.
