Overview in separate control

Hi Stoyan

It is possibe to have the diagram in a separately instanced control from teh overview?  I tried this, exposing the diagram from the first control via a property and referenceing it from the second, but this didn't seem to work.


Many thanks


Paul

Hi Paul,

That's not possible. It's a trade-off we made to allow for using any WPF control as a node, since a control can have just one parent.

You could get something similar to multiple views by using the VisualBrush class. In one view display the Diagram, and in any other view display a rectangle filled with a VisualBrush, whose source is set to the Diagram. When the user activates a view, move the Diagram there, and move the VisualBrush- rectangle to the previously-active view.

I hope that helps,
Stoyan

I am trying to retain zoom factors for VisualBrush and Diagram separately. Meaning that user can set diagram to 100% for editing and sets visualbrush to 20% (readonly) just to look the overall picture..


I have hardtime setting zoom factor for visualbrush as it is being controlled by diagram zoom.
