Issue with StringGrid when setting values using custom editors.

[Hydexon]

Hello, you can help me with some issue with StringGrid when i setting value using custom editors in my case TFileNameEdit Control.

The situation this when i set an Editor in OnSelectEditor of the StringGrid with the following code:

Code: [Select]

procedure TForm1.StringGrid1SelectEditor(Sender: TObject; aCol, aRow: Integer;
  var Editor: TWinControl);
var
Re : TRect;
begin
   if (aCol =1) then begin
    if (aRow = 1) then begin
     Re := StringGrid1.CellRect(1,1);
     Re.Right:= (Re.Right -20);
     FileNameEdit1.BoundsRect := Re;

     StringGrid1.Cells[1,1]  :=FileNameEdit1.FileName;

     FileNameEdit1.Text := StringGrid1.Cells[1,1];
     Editor := FileNameEdit1;
     StringGrid1.SetFocus;
    end;                                           

And running it, and click the specified cell with sample value for example: myfile.txt the FileNameEdit1 don't appear the sample content. and when set a filename in FileNameEdit successfully appears the selected file and then leave the cell only appears the sample value that i set in Design-time, and again select the same cell appears the new text. Where is wrong?, please.

Thanks

The line  StringGrid1.Cells[1,1]  :=FileNameEdit1.FileName; is not necessary, in OnSelectEditor you only need to setup your editor, usually you update the editor with the content of cell so  FileNameEdit1.Text := StringGrid1.Cells[1,1]; should do it. What is missing it seems to be a way to update the grid when you choose a filename, for FilenameEdit component try OnAcceptFilename event, there you can do Stringgrid1.Cells[1,1] := Value (value is a parameter of OnAcceptFilename event), or if you allow manual editing try FilenameEdit's OnEditingDone event, etc.
