Possible Drop Target offset bug
posted

The behavior that I am about to describe appeared when I upgraded from v10.3 to v11.1

My application has a 2x2 grid.  I have a DockManager located in row=1 col=1.  In one of the content panes in the DockManager, I added a DropTarget.  When I drag a component into the content pane, the drop target location seems to be offset by the width of col=0 and the height of row=0 of the grid.

I did a sanity check by moving the DockManager to row=0 and col=0 and I did not see this offset issue.  Is this a bug or am I missing something?  I did not see this in v10.3.

Thank you.

    Hello,
    Could you please attach a sample or send us a snippet showing how do you set up the layout and the drop target. I’ve tested it against 11.1RTM and it seems to be fine:
    Here is my code:
    <ig:XamDockManager x:Name="igXamDockManager" PinBehavior="AllPanes"
                       Grid.Row="1" Grid.Column="1">
        <ig:XamDockManager.Panes>                                               
            <ig:ContentPane Header="DragSource" Location="Left">
                <StackPanel Background="White" Orientation="Horizontal">
                    <Border>
                        <Image Height="50" Width="50" Source="find.png" Stretch="Fill">
                            <ig:DragDropManager.DragSource>
                                <ig:DragSource IsDraggable="True">
                                </ig:DragSource>
                            </ig:DragDropManager.DragSource>
                                   
                        </Image>
                    </Border>
                    <!-- Add more elements -->
                </StackPanel>
            </ig:ContentPane>
                   
            <ig:ContentPane Header="DropTarget" x:Name="rightPane1" Location="Right">               
                <Image x:Name="TargetPanel" Source="find.png" Stretch="Fill">
                    <ig:DragDropManager.DropTarget>
                        <ig:DropTarget IsDropTarget="True"
                                        DropTargetMarkerBrush="Yellow">
                        </ig:DropTarget>
                    </ig:DragDropManager.DropTarget>
                </Image>                   
            </ig:ContentPane>
                   
        </ig:XamDockManager.Panes>
    </ig:XamDockManager>
    And dragging the item over the target makes it highlighted in yellow.  
    Regards.
