Shrinking GoView

GoDiagram (6 and previous)
1

Hi,

When i populate the view it grows according to the position of the go entities and its fine. however after i clear it (remove all the go entities) it remains in the same size. how can i make it shrink to its original size (the size it was when i first created it with out any go entities)?
i tried using the SetAutoSizeMode function of the goview with the GrowAndShrink enum but it didn't do the trick.
can you help?
thanks,
Adi

view.Document.Bounds = view.Document.ComputeBounds();

Jake,
After doing so, it looks like nothing happens (although i believe it shrinked the document) then, when i touch the scroll bar i get an ArgumentOutOfRangeException from your side. here is the stack trace:

well, we have multiple threads going here with scrolling and such, so I may not be keeping things straight between them.

Try setting view.DocPosition to bounds.TopLeft after computing the bounds. (Actually, check your old email from January about CenterDoc... related to this)
