Another issue with a recent TDBAdvGrid update (not sure when it crept in but it wasn't in the version I was using late last year).
I have a cell with a button editor of type edNumericEditBtn. If you click on the cell the button appears. If you then scroll the grid with the mouse wheel or scrollbar the button does not hide but remains floating on the screen and clickable even when the grid is taken out of edit mode.
I have been unable to reproduce this.
To test this, a edNumericEditBtn editor type was set for column 3 in the demo app ADOEditing in the DBAdvGrid samples folder but no issue could be seen here.
How exactly can we reproduce this?
I was able to reproduce this in your sample program. I'm sending you the code. There were a few grid properties I changed to match my instance. I think DirectEdit maybe the culprit.
