Enables the Combo Box’s multi-column mode.

Namespace: DevExpress.Web.Bootstrap

Assembly: DevExpress.Web.Bootstrap.v23.1.dll

NuGet Package: DevExpress.Web.Bootstrap


public bool EnableMultiColumn { get; set; }

Property Value

Type Default Description
Boolean false

true to enable multi-column mode; otherwise, false.


The Combo Box can be displayed as a table with multiple columns. Each column displays data from a corresponding data source field. A column header is generated based on its specified field name.

To enable multi-column mode in a Combo Box, follow the steps below:

  1. Populate the Fields collection with names of data source fields that supply data for Combo Box columns.


    Unbound Combo Box controls do not support multi-column mode. Do not use the EnableMultiColumn property with the Combo Box’s Items collection.

  2. Set the EnableMultiColumn property to true.

  3. (Optional) Use the field’s SettingsMultiColumn property to customize a corresponding column’s header, tooltip, and width.
