Hi,

I try to select all cells of a column by code/program like a multi-select would do.

My code looks like this:

        public void SelectColumn(int index)
        {
            foreach (UltraGridRow gridRow in _Grid.Rows)
            {
                if ((gridRow != null) && (gridRow.Cells.Count > index))
                {
                    gridRow.Cells[index].Selected = true;
                }
            }
        }

It works fine with about 1.000 rows, but with e.g. 10.000 rows, the performance is poor.
Using Infragistics.Win.UltraWinGrid 11.1
