Declaration

Property Value

Type	Default	Description
SortOrder	None

A ColumnSortOrder enumeration value specifying the column’s sort order.

Remarks

Use the SortOrder property to specify whether and how nodes are sorted against a column.

C#
VB.NET

csharp

treeList1.Columns["Department"].SortOrder = SortOrder.Ascending;

TreeList1.Columns("Department").SortOrder = SortOrder.Ascending

To remove sorting against a column set its SortOrder property to None. To clear the sort settings for all columns, call the TreeList.ClearSorting method.

The TreeList.BeginSort and TreeList.EndSort methods allow you to avoid superfluous updates when you change sort settings for multiple columns.

Example

The following code sorts data against the Department and Budget columns. The TreeList.BeginSort and TreeList.EndSort methods wrap the code to avoid superfluous updates.

C#
VB.NET

csharp

using DevExpress.XtraTreeList.Columns;
//...
treeList1.BeginSort();
treeList1.Columns["Department"].SortOrder = SortOrder.Ascending;
treeList1.Columns["Budget"].SortOrder = SortOrder.Descending;
treeList1.EndSort();

Imports DevExpress.XtraTreeList.Columns
' ...
TreeList1.BeginSort()
TreeList1.Columns("Department").SortOrder = SortOrder.Ascending
TreeList1.Columns("Budget").SortOrder = SortOrder.Descending
TreeList1.EndSort()

The TreeListColumn.SortIndex property specifies the sorted column’s position among other sorted columns.
