Hello,

I need connectors and shape to refect property values.

Therefore, I registered connector and shape observers to reflect property changes on relationships and domain elements. I am using OnAssociatedPropertyChanged event handlers.

This works fine when I change a property value. The problem is to present the right aspect of shapes and connectors when the model is re-loaded in memory.

In that case, the events are fired for the connectors but not for the shape. So when the model is loaded, the connectors are presented correctly but the shapes are not.

Any idea?

Thanks

Alain

Hi Alain,

I would like to make the problem clear -- do you observe property changes with codes like this?

public partial class MyShape
{
...
protected override void InitializeInstanceResources()
{
base.InitializeInstanceResources();
MyShape.AssociateValueWith(this.Store, MyElementReferencesTargets.ColorDomainPropertyId);
}

protected override void OnAssociatedPropertyChanged(Microsoft.VisualStudio.Modeling.Diagrams.PropertyChangedEventArgs e)
{
if ("Color".Equals(e.PropertyName))
{
// Update the shape's color with e.NewValue...
}

base.OnAssociatedPropertyChanged(e);

}
}

Regards,
Steven
