We have a problem with the diagram view scroll bar:
When a user drags a node to the right/bottom end of the diagram, the view scroll bar gets enlarged.<?:namespace prefix = o ns = “urn:schemas-microsoft-com:office:office” /><o:p></o:p>
The problem occurs when the user drags a node from a palette and to the diagram and keeps dragging it till the diagram end. We want the diagram view scroll bar will behave the same as in the previous scenario - will get enlarged, but it doest. Why?<o:p></o:p>
How far you can scroll depends on the size of the document compared to the size of the view.
In the case of moving an object within a view, each movement near the end of the document causes the document to get bigger, thus giving more room to scroll in the view.
However, in the case of an external drag from another component, there is no document object that is being dragged, so the size of the document is not automatically increasing due to any autoscrolling.
