[Solved] Implementing Drag and Drop from RadTreeView onto Scheduler

[Sean]

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
