DragDrop RadGridView Catch event Drop

[francois]

Hi,
I have 2 RadListBox I have put a drag and drop event on it and it works!
The probleme is, i have to change value of "IsInGroup" to change the color of the items who change list!
But when i drop items they don't go on the event in "ListBox_Drop" and "ListBox2_Drop"

Code XAML

<telerik:RadListBox  AllowDrop="True" x:Name="ListBox"  Drop="ListBox_Drop"


SelectionMode="Extended" SelectedItem="{Binding SelectedClientAssigned, Mode=TwoWay}" ItemsSource="{Binding ClientAssignedList}" HorizontalAlignment="Left" VerticalAlignment="Stretch" >

   <telerik:RadListBox.ItemTemplate>

      <DataTemplate>

         <TextBlock Text="{Binding Alias}" Style="{Binding IsInGroup, Converter={StaticResource StyleFunctionConverter}}"/>

      </DataTemplate>

   </telerik:RadListBox.ItemTemplate>

   <telerik:RadListBox.DragDropBehavior >

   <telerik:ListBoxDragDropBehavior />

   </telerik:RadListBox.DragDropBehavior>

</telerik:RadListBox>

 

<telerik:RadListBox  AllowDrop="True" x:Name="ListBox2"  Drop="ListBox2_Drop"


SelectionMode="Extended" SelectedItem="{Binding SelectedClientNotAssigned, Mode=TwoWay}" ItemsSource="{Binding ClientNotAssignedList}" HorizontalAlignment="Left" VerticalAlignment="Stretch" >

   <telerik:RadListBox.ItemTemplate>

      <DataTemplate>

         <TextBlock Text="{Binding Alias}" Style="{Binding IsInGroup, Converter={StaticResource StyleFunctionConverter}}"/>

      </DataTemplate>

   </telerik:RadListBox.ItemTemplate>

   <telerik:RadListBox.DragDropBehavior >

   <telerik:ListBoxDragDropBehavior />

   </telerik:RadListBox.DragDropBehavior>

</telerik:RadListBox>

Code XAML.CS

private void ListBox2_Drop(object sender, Telerik.Windows.DragDrop.DragEventArgs e)
{
   ...
}

private void ListBox_Drop(object sender, Telerik.Windows.DragDrop.DragEventArgs e)
{
   ...
}

thank you

Hello Francois,

What I can suggest you would be to implement a custom ListBoxDragDropBehavior and override the DragDropCompleted method in order to modify the dropped item as needed:

public class CustomListBoxDragDropBehavior: ListBoxDragDropBehavior
{
    public override void DragDropCompleted(DragDropState state)
    {
        // implement custom logic
        base.DragDropCompleted(state);
    }
}

You will be able to find the dropped item in the DraggedItems property of DragDropState parameter.

Hope this helps.
