    Hi im using RadComboBox in Silverlight 4. Im using  MVVM ,Riaservices prism for my application.
    I need a a Confirmation window on selection change. The window should appear when user tries to chage the value in Combo box . If ok it should allow chane no it should not allow the user to change. What event i can use for it??
    Using ASP.net i found events like OnClientSelectedIndexChanging, Using this event and JavaScript the are making it run

       I am not suppose to use Javascript and also i cont find SelectedIndexChanging  event like that.

    Using Silverlight 4 how can i achieve this using MVVM pattern..
     my RadCombobox
    <telerik:RadComboBox Name="comboboxMagazine"  MaxWidth="170"   IsFilteringEnabled="True" IsTextSearchEnabled="True" TextSearchMode="StartsWith" MinWidth="140" Grid.Row="1" Grid.Column="3" Height="20" DisplayMemberPath="MagazineName" 
                      SelectedValuePath="MagazineID" ItemsSource="{Binding MagazineData,Converter={StaticResource AddEmptyItemConverter}}"                                  
                      SelectedValue="{Binding JobRequest.MagazineID, Mode=TwoWay, UpdateSourceTrigger=Explicit, ValidatesOnDataErrors=True, ValidatesOnNotifyDataErrors=True, NotifyOnValidationError=True}">
                    <i:Interaction.Triggers>
                        <i:EventTrigger EventName="SelectionChanged">
