Placing a grid in edit mode programatically.

Question:

How can I programmatically place a grid into edit mode and move the cursor to a predetermined position in the edit box?

Answer:

Place the grid in editor mode, then get a handle to the edit box

and send a EM_SETSEL message, passing the initial position

where you want the cursor to appear, and the positon of the 

ending selection (if you wish to highlight text).



The following example sets the cursor to the second character

in the edit control, and does not select any text.



Example:



procedure TForm1.Button1Click(Sender: TObject);

var

  h : THandle;

begin

  Application.ProcessMessages;

  DbGrid1.SetFocus;

  DbGrid1.EditorMode := true;

  Application.ProcessMessages;

  h := Windows.GetFocus;

  SendMessage(h, EM_SETSEL, 2, 2);

end;
