I am not able to bind the model to goxam palette through xaml . can any one provide help for it
A Palette is just a kind of Diagram, so it’s done in exactly same manner.
All of the samples set the Diagram.Model in code because they want to use the generic classes, but XAML doesn’t support that. But if you define your own model class, inheriting from and implementing one of the generic model classes, then you could set it in XAML:
<go:Diagram . . . >
<local:MyModel . . . />
Also, you could data-bind the Diagram.NodesSource property. If you do, remember to bind Mode=TwoWay.
