I have tried to use this, http://www.codeproject.com/KB/silverlight/MultiSelComboBox.aspx. This is not running unless I change target silverlight version to 3. — user420054, Dec 30 '10 at 17:53

If you want to display checkboxes as items of a comboBox, a simple DataTemplate shoud work:

    <ComboBox Name="combo" >
        <ComboBox.ItemTemplate>
            <DataTemplate>
                <CheckBox Content="{Binding Text}" IsChecked="{Binding IsChecked,Mode=TwoWay}"/>
            </DataTemplate>
        </ComboBox.ItemTemplate>
    </ComboBox>

Now on your code behind create an ObservableCollection ChekItem is a basic class:

public class CheckItem
{
    public string Text { get; set; }
    public bool IsChecked { get; set; }
}

and associate it to your comboBox ItemsSource. If you want to know what items are checked, is simple:

var checkedItems = myList.Where(i => i.IsChecked == true);
