    Attached is a project taken from these forums that was provided as a solution to this problem. I can successfully fire an OnDragQuery operation but what I need is to implement OnDropInfo and OnDropQuery using MVVM. Is there an example of this being done?


    MVVM Light 3

    XAML:
    <telerik:RadScheduler Name="scheduler" 
                                              VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch" 
                                              AvailableViewModes="Month" 
                                              ShowsConfirmationWindowOnDelete="False" 
                                              Style="{StaticResource RadSchedulerStyle1}" 
                                              AppointmentsSource="{Binding Appointments, Mode=TwoWay}" 
                                              telerikDragDrop:RadDragAndDropManager.AllowDrop="True" AllowDrop="True">
                                                
                            <i:Interaction.Triggers>
      
                                <local:DropQueryRoutedEventTrigger EventName="DropQuery">
                                    <cmd:EventToCommand PassEventArgsToCommand="True" Command="{Binding DropQueryCommand, Mode=TwoWay, Source={StaticResource Locator}}" />
                                </local:DropQueryRoutedEventTrigger>
      
                            </i:Interaction.Triggers>
                        </telerik:RadScheduler>


    ViewModel:
    DropQueryCommand = new RelayCommand<DragDropQueryEventArgs>(DropQuery);
    ......
      
    private void DropQuery(DragDropQueryEventArgs e)
            {
      
            }
      
    public RelayCommand<DragDropQueryEventArgs> DropQueryCommand
            {
                get;
                private set;
            }

    Hi Sean,

     You might want to look at this blog post that illustrates how to achieve drag/drop functionality in MVVM - http://blogs.telerik.com/tsvyatkokonov/posts/10-12-15/using_commands_with_raddraganddropmanager_for_wpf_and_silverlight.aspx
