If I understand you correctly you want to prevent dragging outside of the diagram's viewport (the visible render surface). Am I right? If so, you can take a look at the CustomServices SDK example which demonstrates how you can restrict the dragging to specified bounds. Basically, you can create a custom dragging service and override its drag events.
I hope this helps.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
