TreeListOptionsBehavior.AutoPopulateColumns Property

Gets or sets whether columns should be automatically created for all the fields in the underlying data source when the Tree List doesn't contain any columns.

Namespace:DevExpress.XtraTreeList
Assembly:DevExpress.XtraTreeList.v19.1.dll

Expanded Syntax

Property value

Type: Boolean
true if the columns are created automatically when the Tree List doesn't contain any columns; otherwise, false.
The default is true.

Expanded Remarks

This property determines whether the TreeList.PopulateColumns method is called automatically when a data source is assigned to the Tree List which doesn't contain any columns. The TreeList.PopulateColumns method creates TreeListColumn objects for all the fields in the underlying data source and make these columns visible.

Set the AutoPopulateColumns property to false to prevent columns from being automatically created. In this case columns should be manually added to the TreeList.Columns collection.
