Automatic column sorting for any data source allows you to sort against an unlimited number of columns, without writing a single line of code. A column's current sort order is indicated by a sort glyph displayed on the right edge of the column header. If the column is not sorted, the sort glyph is hidden.
Click a column header to sort data against a data column, or change the column's sort order. To sort data against multiple columns, click a column header while holding down the SHIFT key. Clicking a sorted column header while holding down the CTRL key removes sorting for that column, but preserves the sort conditions of other columns.
Set the SettingsBehavior.AllowSort option to true to enable end-user sorting.
The ASPxTreeList also provides a client-side API that enables you to apply sorting on the client side. To do this, use the ASPxClientTreeList.SortBy method.
