Clearing and Recreating a Diagram

[Phil Sullivan]

I am creating a simple diagram with nodes and connections. The diagram control is added in XAML. In a handler I clear the connecions and Nodes through this method:

diagramModel.Nodes.Clear();
diagramModel.Connections.Clear();

When I try to recreate the diagram using the same code all of the nodes get added to the top left of the diagram and overlap each other. I am using the HeierarchialTree layout. Do I need to do something else to clear the diagram?

This is regarding the WPF diagram, my apologies that I submitted it in ASP.NET forum.

Stumbled accross the solution:

HierarchicalTreeLayout tree = new HierarchicalTreeLayout(diagramModel, diagramView);

tree.RefreshLayout();
