WPF Diagram Control - Bind Item Positions to Source Objects

This example demonstrates how to bind positions of diagram items to source properties (in two-way mode) when you generate these items from a source collection.

Create a DiagramBinding object, specify target and source properties and binding mode, and assign the object to the DiagramItem.Bindings property:

<dxdiag:DiagramShape.Bindings>
    <dxdiag:DiagramBinding PropertyName="Position"
                           Expression="Position"
                           Mode="TwoWay"/>
</dxdiag:DiagramShape.Bindings>

Handle the DiagramDataBindingBehaviorBase.CustomLayoutItems event to disable the default layout algorithm.
