Dim keyRow As Integer
Dim ascending As Boolean
Dim comparer As IComparer
Dim value As Boolean
value = instance.SortColumns(keyRow, ascending, comparer)
public bool SortColumns(

   bool ascending,
   IComparer comparer

Return Value

Boolean: true if successful; false otherwise


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.


This example sorts a range of columns.
