BandBase.OverlayHeaderByChildren Property

Get or sets the value that indicates whether the band children overlay the band header. This is a dependency property.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v19.1.Core.dll

Declaration

C#

public bool OverlayHeaderByChildren { get; set; }

VB.NET

Public Property OverlayHeaderByChildren As Boolean

Property Value

Type	Description
Boolean	true, if band’s children overlay the band header; otherwise, false.

Remarks

When the OverlayHeaderByChildren property is set to true, the band’s children (child bands and columns) hide the band’s header and occupy its space.

Note

When the band’s OverlayHeaderByChildren property is set to true, and the band has no children, the band’s header will be displayed.

Note

The OverlayHeaderByChildren property is not in effect when exporting grid’s data.

Example

The following code snippet demonstrates how to use columns and bands in the grid control simultaneously.
