Public Property PanningTool As PanningTool

[CategoryAttribute("Tools")]
public PanningTool PanningTool {get; set;}

Property Value

Normally the DragSelectingTool takes precedence, because both tools operate on a left-button-mouse-down in the background followed by a mouse-drag. But DragSelectingTool precedes this PanningTool in the list of MouseMoveTools, so if it is applicable, it is always chosen first.

To enable this mode-less panning tool, you can remove the drag-selecting tool or you can disable that tool by disallowing selection. Remove the tool in WPF XAML by:

              <go:Diagram ... DragSelectingTool="{x:Null}" >
                . . .
              </go:Diagram>
            

              myDiagram.DragSelectingTool = null;
