Rowstyle performance in a GDBG

[Tomas]

I have some problems with slow perfomance using rowstyles in a GridDataBoundGrid.

If I add the following code into the QueryCellInfo event the grid gets so slow that it is hard to work with it:

if((e.RowIndex > 0) && (e.RowIndex < currentGridModel.RowCount))
{
if((Convert.ToInt32(currentGridModel[e.RowIndex,17].CellValue) == 0))
{
e.Style.ReadOnly = false;
}
else
{
e.Style.ReadOnly = true;
e.Style.BackColor = Color.White;
}
e.Handled = true;
}

I already have other style changes made in this event without any major performance issues, and the grid contains no more than 200 rows.

I can see the same tendence with the last row to which I have added bold and italic style. It always feel more slow than an ordinary row when I scroll it into view etc.

Any ideas about what I can do to speed things up?

I forgot to say that the above code is placed within an if-statement looking like this:

if(e.ColIndex == -1)

I do this to know that is it a specific rowstyle I''m working with.

I have solved this issue. Instead of fetching validation values from the grid, as this probably triggers even more events, I changed the code to get them from the datasource instead and gained LOTS of performance.
