Remarks

DragDropPointBehavior is part of ClientUI drag-drop framework library, to learn more about ClientUI Drag-drop Library see Drag-drop Framework Overview.

To make an UIElement dragable, simply attach a DragDropBehavior to that particular elements as shown in the XAML code below.

XAML Copy Code 
<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
    <i:Interaction.Behaviors>
        <Intersoft:DragDropBehavior/>
    </i:Interaction.Behaviors>
    <Image Source="folder.png" Height="64" Width="64"/>
    <TextBlock Text="My Archive" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</StackPanel>

In the above sample, the DragDropBehavior is attached to a StackPanel that has an image and a text element.

The side effect of this concept is that you can start the drag-drop operation by dragging any elements within the StackPanel, which might not always be desirable. To make only certain elements dragable, you attach a DragDropPointBehavior to the desired dragable element which is the children element of the StackPanel.

The following code shows how you can limit the drag source to an Image element.

XAML Copy Code 
<StackPanel HorizontalAlignment="Left" VerticalAlignment="Top">
    <i:Interaction.Behaviors>
        <Intersoft:DragDropBehavior IsDragable="False"/>
    </i:Interaction.Behaviors>
    <Image Source="folder.png" Height="64" Width="64">
        <i:Interaction.Behaviors>
            <Intersoft:DragDropPointBehavior IsDragable="True"/>
        </i:Interaction.Behaviors>
    </Image>
    <TextBlock Text="My Archive" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</StackPanel>
