TreeListColumn

null

A TreeListColumn object specifying the column in which tree list nodes display their expand/collapse buttons.

By default, the HierarchyColumn is set to null. In this case, tree list nodes that have children display their expand/collapse buttons in the first column, as in the figure below.

TreeList_HierarchyColumn

Use the HierarchyColumn property to explicitly specify the column that will display the node expand/collapse buttons.


treeList1.HierarchyColumn = colLOCATION;

TreeList_HierarchyColumn_Custom

You can also specify the hierarchy column with the TreeList.HierarchyFieldName property. The TreeList.HierarchyFieldName property has priority over the HierarchyColumn property.
