Hello,
I fill up the Diagram with Circle shapes which connected between them by RadDiagramConnections.
I use this line of code in order to add shapes from code behind:
diagram.Items.Add(line); // line is a RadDiagramConnection
There are 1500 connections.
Approximately this action takes 2-3 seconds.
During this action all my GUI is stuck.
Is there something like SuspendLayout while the population process is being in progress?
Could you suggest a solution for this issue?
Thanks.

Hello Igor,
Unfortunately there's no built-in mechanism for layout suspending because only the main(UI) thread can change the layout (add shapes to the visual tree). There's a possible workaround - you could try to add the connections in sets using a dispatcher timer. This way the UI won't be frozen but the actual operation will take more time depending on your interval and set size.
I've attached a sample project demonstrating this approach so could you please examine it and if you have more questions feel free to ask.
