The selection in the AutoCompleteBox will display the property of the selected item to which the DisplayMemberPath points.

Furthermore, the control exposes the following properties and events for handling the user selection.

• SelectedItem: Gets or sets the data item that is selected.
• SelectedItems: Gets the data items that participate in the selection. It is useful in case multiple selection is used.
• SelectedValue: Gets or sets the selected property value.
• SelectedIndex: Gets or sets the index of the selected item.
• SelectedValuePath: Gets or sets the property path of the property used for the selected value.

Multiple Selection

By default, RadMultiColumnComboBox will perform a single selection. In order to enable a multiple selection, the SelectionMode of the control can be set to Multiple.

Example 1: Setting the SelectionMode to Multiple

• XAML

<telerik:RadMultiColumnComboBox VerticalAlignment="Top" DisplayMemberPath="Name" SelectionMode="Multiple"> 
        <telerik:RadMultiColumnComboBox.ItemsSourceProvider> 
            <telerik:GridViewItemsSourceProvider ItemsSource="{Binding Clubs, Source={StaticResource MyViewModel}}"/> 
        </telerik:RadMultiColumnComboBox.ItemsSourceProvider> 
    </telerik:RadMultiColumnComboBox>

SelectionChanged event

Each time a select or deselect operation is applied, the SelectionChanged event will be fired.

Example 2: Handling the SelectionChanged event

• XAML

    private void RadMultiColumnComboBox_SelectionChanged(object sender, SelectionChangeEventArgs e) 
    { 
 
    } 

The event arguments expose the following collections.

• AddedItems: a collection of the item(s) that has/have been added to the selection
• RemovedItems: a collection of the item(s) that has/have been removed from the selection
