Oh, okay. Now i know what you mean.

The grid already sorts strings alphabetically. But if you want strings that contain numbers to be sorted by their numeric values, you would need a SortComparer for that.

That should be a very easy SortComparer, though. All you have to do is get the text of each cell and use string.CompareOrdinal.

    public class OrdinalSortComparer : IComparer
    {
        int IComparer.Compare(object x, object y)
        {
            UltraGridCell xCell = (UltraGridCell)x;
            UltraGridCell yCell = (UltraGridCell)y;

            /// Sanity checks
            if (xCell == yCell)
                return 0;

            if (null == xCell)
                return 1;

            if (null == yCell)
                return -1;

            string xText = xCell.Text;
            string yText = yCell.Text;
            return string.CompareOrdinal(xText, yText);
        }
    }

Hi Mike,

Thanks I will implement the Natural sort.

Natural sort is like if we have string data column and want to sort in numeric order for numbers and alphabetic order for words.

e.g. values are: 1 , 3, 10, abc

String (alphabetic) order would be: 1, 10, 3, abc; but Natural sort order would be: 1, 3, 10 , abc

Thanks
