Grouping
The MultiColumnComboBox supports binding to a grouped data source.
To group the data by using the custom DataSource configuration, define a datasource
group expression. For more information, refer to the demo on grouping the data in the MultiColumnComboBox.
The data source sorts the grouped data either in ascending or descending order. To persist a specific group order, use the server grouping feature. To define the
serverGrouping
option, use the DataSourceServerGrouping
method.
