ASPxTreeList.AutoGenerateColumns Property

Gets or sets whether columns are automatically created for all fields in the underlying data source.

Namespace: DevExpress.Web.ASPxTreeList

Assembly: DevExpress.Web.ASPxTreeList.v18.2.dll

Declaration

C#

[DefaultValue(true)]
public bool AutoGenerateColumns { get; set; }

VB.NET

<DefaultValue(True)>
Public Property AutoGenerateColumns As Boolean

Property Value

Type	Default	Description
Boolean	**true**	true to automatically create columns for all fields in the underlying data source; otherwise, false.

Remarks

The AutoGenerateColumns property specifies which field’s data is rendered by the ASPxTreeList. By default, this property is set to true. This forces the ASPxTreeList to render each field from the data source as a column. The order of columns is the same as the order of fields in the data source.

You can also manually control which columns are to appear in the ASPxTreeList by setting the AutoGenerateColumns property to false. In this case, you should manually add columns to the ASPxTreeList.Columns collection. The AutoGenerateColumns property cannot be set to true, if this collection contains any columns.

Note

By default, service columns bound to the ASPxTreeList.KeyFieldName and ASPxTreeList.ParentFieldName data fields are not created. To automatically create columns for these data fields, enable the ASPxTreeList.AutoGenerateServiceColumns option.
