Open the MultiColumnComboBox to see the customized appearance.


RadMultiColumnComboBox provides templates so you can fully control the appearance of the dropdown:

  • Column Template
  • Column Header Template
  • Header Template
  • Footer Template
  • No Data Template
  • Group Template
  • Fixed Group Template

The template and the header-template can be defined for each of the columns available in the widget. The rest of the templates are defined for the entire popup of the widget. The templates in the MultiColumnComboBox are rendered by using Kendo UI templates.

By default the DataItem for an item contains the DataTextField, DataValueField and the DataFields declared in the Columns. If more fields from the server-side DataItems are needed, the properties can be added to the DataKeyNames collection, separated by a comma.
