GridColumn.SortIndex Property

Gets or sets the column's position among sorted columns.

Namespace:DevExpress.XtraGrid.Columns
Assembly:DevExpress.XtraGrid.v17.2.dll

Expanded Syntax

Property value

Type: Int32
An integer value representing the zero-based column's index among sorted columns. -1 if data is not sorted by this column.
The default is -1.

Expanded Remarks

Grid Views allow data sorting by multiple columns. Once a column is sorted, it is automatically added to the View's ColumnView.SortedColumns collection. If no columns were previously sorted, the column becomes the only element in the collection, and so, gets the 0 sort index. If sorting by one more column, the newly sorted column is appended to the collection, and so, gets the 1 index, etc.

If the column's SortIndex property value is changed from -1 to a non-negative integer, the column is added to the sorted column list. The column's SortOrder property is automatically set to DevExpress.Data.ColumnSortOrder.Ascending. Inversely, setting a column's SortIndex property to -1 cancels data sorting by this column.

If a column has been sorted and you want to change its sort order, use the methods provided by the ColumnView.SortInfo object (for instance, the GridColumnSortInfoCollection.Insert method).

See Sorting in Code to learn more.
