I use dapfor wpf gridcontrol and all sorting are simple. To solve this problem ICustomSort interface has been implemented. C# class RatingComparer : ICustomSort { public int Compare(Row row1 Row row2 string fieldId object value1 object value2 int defaultResult) { int result = defaultResult; if (fieldId == Rating) { string rating1 = (string) value1; string rating2 = (string) value2; if(!string.IsNullOrEmpty(rating1) && !string.IsNullOrEmpty(rating2)) { //compare two ratings: rating1 > rating2 => result is positive // rating1 == rating2 => result = 0 // rating1 result is negative //result = ... } } return result; } } grid.CustomSort = new RatingComparer();

Please find the below link for more data sorting with screen shot & code explained. Headerheader=grid.Headers[0]; Columncolumn1=header[ Column1 ]; Columncolumn2=header[ Column2 ]; //Sortbythefirstcolumn column1.SortDirection=SortDirection.Ascending; //Turnonthemultiplesortbythesecondcolumn column2.SortDirection=SortDirection.Descending; //Enumerateallsortedcolumns foreach (Columncolumn in header.SortedColumns) { //Somecodehere... } //Clearthesort header.SortedColumns.Clear(); http://www.dapfor.com/en/wpf-suite/gridcontrol/tutorial/tutorial-part9 Mark as answer if helpful
