Hello,I constantly stumble with the behaviour of the TDBGrid. I understand that it's a complex component, but every time I find an issue an Luiz fixes it, two more pop up (or an older one resurfaces). The latest episode of the saga is the futility of using a custom editor (with OnSelectEditor), since the grids then sets the value of the field using this snippet of code if (FEditor<>nil) and FEditor.Visible then begin Msg.LclMsg.msg:=GM_GETVALUE; Msg.grid:=Self; Msg.Col:=FCol; Msg.Row:=FRow; Msg.Value:=GetCells(FCol, FRow); FEditor.Dispatch(Msg); SetEditText(Msg.Col, Msg.Row, Msg.Value); end; and this only works with the editors defined in Grids.pas, the only ones managing the GM_GETVALUE message. For other kinds of editors the result depends on how you move in the grid: it could either maintain the value the editor set or reset it to an empty string. I think I will file a bug once I can create a simple project, but in the meantime if somebody has an idea on how to solve it, it would be appreciated.
