Property Value

Type	Default	Description
Boolean	false	true to enable multi-column mode; otherwise, false.

Remarks

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.

   Note

   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.
