  1. var
  2.   SomeGrid : TStringGrid
  3. ...
  4. begin
  5. ..
  6.   SomeGrid:= MainForm.FindComponent(strSTG) as TStringGrid
  7.   with SomeGrid do
  8.   begin
  9.     movRow(Row, Row + 1, SomeGrid)
  10.     ..
  11.   end
  12. ...
  13. end
  14.

Is it possible to do that without defining a new TStringgrid ?

To make clear: You do not define a new stringgrid only a reference to it.

And I have no idea if you could do without as the snippet you posted is too small to be able to provide an (accurate) answer. There is absolutely no context atm.

When using the with statement it is not possible to reference the (in this case) object other then the example I provided (unless there is additional context that might be able to help you out there)

Hi
Ok, here comes nasty!
If you beforehand, store a reference to the stringgrid in its own "Tag" property:
Code: Pascal  [Select][+][-]
  1. procedure TmainForm.FormCreate(Sender: TObject);
  2. begin
  3.   StringGrid1.Tag:= ptrint(StringGrid1); // <- nasty business!
  4. end;
  5.  

then you would be able to do something like this:
Code: Pascal  [Select][+][-]
  1.   with(mainForm.FindComponent(strSTG)as TStringGrid)do begin
  2.     movRow(Row,Row + 1, TStringGrid(Tag)); // <- nasty business!
  3.   end;
  4.  
%) It was the voices, they told me to do so....  O:-)
