Reorder RadListBox

[Kathryn]

I am trying to implement a RadListBox that allows users to reorder the items within itself.  While I have found some old examples of this as well as the sdk examples, I keep getting the following error when I include the ItemContainerStyle reference:

"A style intended for type 'Telerik_Windows_Controls_RadListBox_0_206042439' cannot be applied to type 'ContentPresenter'.

 

In my XAML, I have this:

......

<UserControl.Resources>
        <vm:AgentPreferencesViewModel x:Key="ViewModel" />
        <cnv:CheckBoxConverter x:Key="CheckBoxConverter" />
        <Style TargetType="telerik:RadListBox" x:Key="DraggableItem">
            <Setter Property="telerik:RadDragAndDropManager.AllowDrag" Value="True" />
            <Setter Property="telerik:RadDragAndDropManager.AllowDrop" Value="True" />
            <Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True"/>
        </Style>
    </UserControl.Resources>

......

<telerik:RadListBox ItemContainerStyle="{StaticResource DraggableItem}"
                            ItemsSource="{Binding GridHeaders}"
                            DisplayMemberPath="Name"
                            Grid.Column="0"
                            Grid.Row="0"
                            Margin="20">
                <telerik:RadListBox.DragVisualProvider>
                    <telerik:ScreenshotDragVisualProvider />
                </telerik:RadListBox.DragVisualProvider>
                <telerik:RadListBox.DragDropBehavior>
                    <telerik:ListBoxDragDropBehavior AllowReorder="True" />
                </telerik:RadListBox.DragDropBehavior>
            </telerik:RadListBox>

Hi Kathryn,

The Style set to ItemContainerStyle property of RadListBox should have its TargetType set to

RadListBoxItem (not RadListBox).

I'd suggest you check the Drag and Drop Overview topic in our documentation as well as the ListBox Drag and Drop example at WPF Demos.
