Own sorting in Infragistics' ultraGrid

My application's user submitted request to add possibility to change way how decimal columns are sorted in grid.

He wanted sort decimals by absolute values.

Turned out it is pretty easy to implement using IComparer interface + grid SortComparer property.

Final effect:

Example code:

<br />ultraGrid1.DisplayLayout.Bands[0].Columns[4].SortComparer = new GridComparerABS();<br />public class GridComparerABS : IComparer {<br />        public int Compare(object x, object y) {<br />            UltraGridCell xCell = (UltraGridCell)x;<br />            UltraGridCell yCell = (UltraGridCell)y;                                    <br />            decimal decX = (decimal) xCell.Value;<br />            decimal decY = (decimal) yCell.Value ;<br />            return decimal.Compare( Math.Abs(decX), Math.Abs( decY ) );<br />        }<br />}<br />
