  • BootstrapListBoxProperties.EnableMultiColumn Property

    Enables a List Box’s multi-column mode.

    Namespace: DevExpress.Web.Bootstrap

    Assembly: DevExpress.Web.Bootstrap.v25.1.dll

    NuGet Package: DevExpress.Web.Bootstrap

    Declaration

    [DefaultValue(false)]
    public bool EnableMultiColumn { get; set; }

    Property Value

    Type Default Description
    Boolean false

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

    Remarks

    The List 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 List Box, follow the steps below:

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

      Note

      Unbound List Box controls do not support multi-column mode. Do not use the EnableMultiColumn property with the List 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.
