Currently it is not possible to select multiple rows in RadMultiColumnComboBox.

In our next release (R1 2017) we will include an example demonstrating how to implement a multiple selection with checkboxes in RadMultiColumnComboBox. The example will be available in our DemoApplication, section MultiColumn ComboBox.

Am interested in this feature as well (multi-column with checkbox)
Thanks very much
