Sorting

Expanded End-User Sorting

The SpreadsheetControl provides the capability to sort data by text (alphabetically, according to the current culture), numbers, dates and times in one column. The end-user can select a range in one column and on the Data tab, in the Sort & Filter group, click Sort A to Z for ascending order or click Sort Z to A for descending order.

If multiple columns are selected, the range is sorted by the first column.

Expanded Sorting Programmatically

The Spreadsheet API provides a Worksheet.Sort method, which allows sorting in ascending or descending order in the same manner as the sort commands available to the end-user. However, the method has several overloads with serious advantages. You can specify the column by which to sort a multi-column range, sort by multiple columns or use a custom comparer.

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E4944.

To sort by multiple columns, perform the following steps.

  • Create the SortField object for each of the columns from which to sort. Specify the position of this column within the range using the SortField.ColumnOffset property and assign a comparer using the SortField.Comparer property. Instead of implementing your own comparer with the System.Collections.Generic.IComparer`1[[DevExpress.Spreadsheet.CellValue]] interface, you can use one of the built-in comparers which are responsible for sort operations performed by end-users. There are two built-in comparers - Worksheet.Comparers.Ascending is used for sorting in ascending order; Worksheet.Comparers.Descending is used for sorting in descending order.
  • Create a list containing sort fields.
  • Use the Worksheet.Sort method with two parameters - the first is the Range to sort, the other is the list of sort fields.
