Parameters

Name Type Description

Type Description

Remarks

The ASPxTreeList allows data sorting by multiple columns. Any previous sorting is not cleared when calling the SortBy method. The new sort order applies an additional sorting condition to the one previously applied. The newly sorted column is appended to the collection of sorted columns. Its index within the collection can be obtained via its TreeListDataColumn.SortIndex property.

If no sorting is applied to the column, the SortBy method sorts data in the ascending order.

Sorting is allowed if the TreeListSettingsBehavior.AllowSort property is set to true.
