Hi Pavel,

The panning and scrolling events have not been implemented yet and therefore they wont be available in Volume 4 release. We have added these features to our feature queue and we will implement them in our future releases. The implementation will also depend on other factors like code complexity, code compatibility and product design.

Please let us know if there are any concerns.

Could you suggest some temporal workarround for this?

Like to put some 1 pixel node and play with checking of screen position periodically or handle some win32 events or reflection usage?

Hi Pavel,

As we have already mentioned in our response in another forum, you can use the following code to get the screen coordinates of the node . The NodeDrag event will fire each time the node is dragged and so you can periodically check the screen coordinates.


diagramView.NodeDragEnd += new NodeEventHandler(diagramView_NodeDragEnd);

void diagramView_NodeDragEnd(object sender, NodeRoutedEventArgs evtArgs)
{
Node n = evtArgs.Node;
Point screenpoint = diagramView.PointToScreen(new Point(n.OffsetX, n.OffsetY));
}

Please let us know if there are any concerns.
