value = instance.SortColumns(keyRow, ascending, comparer)
public bool SortColumns( 
   int keyRow,
   bool ascending,
   IComparer comparer
)

Parameters

keyRow
Index of the row to use as a key to sorting
ascending
Whether to sort in ascending order
comparer
IComparer object used to compare the values

Return Value

Boolean: true if successful; false otherwise
Remarks

This method can be used to sort all the columns in the sheet. It is similar to the simple method, SortColumns(Int32,Boolean), but adds an option for specifying the way of comparing that is used. Use this method to do a sort beyond the comparison technique provided by the comparer in the .NET framework.

This does not affect the data model, only how the data is displayed. Different overloads provide different ways to sort the columns. For a discussion of sorting, refer to Managing Sorting of Rows.

Example
This example sorts a range of columns.
fpSpread1.ActiveSheet.SetValue(0, 0, "S");
fpSpread1.ActiveSheet.SetValue(0, 1, "E");
fpSpread1.ActiveSheet.SetValue(0, 2, "A");
fpSpread1.ActiveSheet.SetValue(0, 3, "K");
fpSpread1.ActiveSheet.SetValue(1, 0, "W");
fpSpread1.ActiveSheet.SetValue(1, 1, "G");
fpSpread1.ActiveSheet.SetValue(1, 2, "P");
fpSpread1.ActiveSheet.SetValue(1, 3, "V");
fpSpread1.ActiveSheet.SetValue(2, 0, "O");
fpSpread1.ActiveSheet.SetValue(2, 1, "L");
fpSpread1.ActiveSheet.SetValue(2, 2, "Q");
fpSpread1.ActiveSheet.SetValue(2, 3, "H");
fpSpread1.ActiveSheet.SortColumns(0, false, System.Collections.Comparer.Default);
FpSpread1.ActiveSheet.SetValue(0, 0, "S")
FpSpread1.ActiveSheet.SetValue(0, 1, "E")
FpSpread1.ActiveSheet.SetValue(0, 2, "A")
