Displays data in a tabular form and organizes columns into bands.

Namespace: DevExpress.XtraGrid.Views.BandedGrid

Assembly: DevExpress.XtraGrid.v24.2.dll

Declaration

C#

public class BandedGridView :
    GridView

VB.NET

Public Class BandedGridView
    Inherits GridView

Related API Members

The following members return BandedGridView objects:

• BandedGridColumn.View
• BandedGridColumnCollection.View
• GridBand.View
• GridBandCollection.View
• GridBandColumnCollection.View

Remarks

Banded Grid View displays data in a tabular form and organizes columns into bands. End-users can drag band headers to rearrange bands or to hide them.

Demos:

• Banded Views
• Excel Style Filtering
• Master-Detail (advanced)

Bands can be arranged into a tree. The BandedGridView.Bands property specifies the root band collection. Each band holds its child bands in the GridBand.Children collection. To add columns to a band, use the GridBand.Columns property.

Refer to the Banded Grid Views topic for additional information.

Example

This example shows how to create a GridControl, while presenting its underlying data using a banded grid format (BandedGridView). The example creates three bands (Main, Address and Phone), adds columns to the bands and customizes the background color for the third band and its columns.
