Sorry Dave,
That's not it yet.
Here is my code:
StringGrid1.InsertColRow(false,1);//Notice it is creating a new
line at
the top of the grid
StringGrid1.Col := 1;
StringGrid1.Row := 2;
And this works fine. The line is created at the top and the focus
moved to the second row. no problems there.
However, when you move to any cell in the newly created row (either
by
clicking or keyboard) the access violation occurs?
Any thoughts?

Alex,
If you did something like: Grid.Row := Grid.RowCount , this will
fail
because the rows range from 0 to (RowCount - 1). I would expect
that
Grid.InsertColRow(false,Grid.RowCount) would also fail. The same
applies
to Grid.Cells[col,row]. For example, to add a new row after the
last,
you could use code like this ...
var wRow: integer;
begin
wRow := SGItems.RowCount;
SGItems.RowCount := SGItems.RowCount + 1;
SGItems.Cells[1, wRow] := CBProdCode.Text;
SGItems.Row := wRow; // highlights the new row
end;

With the first instance I did. In the second instance
(InsertColRow())
the grid tries to focus the cell automatically and also causes
an acces
violation.

Hi
I need to insert a new row into a StringGrid. (TStringGrid),
The grid will gladly create the new row (using a construct of
Grid.RowCount := Grid.RowCount + 1 or using
Grid.InsertColRow(false,1)).
However, an access violation occurs immediately when trying
to focus a
cell within the new row.
How are you trying to do this? Are you using Grid.RowCount to
refer to
it?
What am I doing wrong?

Dave.
The given information is not enough to reproduce the problem, I tried
several ways but yet I cannot make it fail.
It's very difficult to "guess" what are your settings in the grid
before the code you write, rowcount, colcount, fixedcols, options,
etc.
The best thing would be that you made a small project just the grid
and the needed code to reproduce the problem, test it, remove all
binaries generated (*.o *.ppu and exe) and attach it, and then say,
if I click this button this fails... or something like this.
