Showing a progress indicator

Good Day,

I'm trying to display a progress indicator while loading/updating the diagram but I cannot get it to work.  My guess is that FlowChart is working on the Gui thread and that I connot interact with it at the same time, but I'm likely missing something. I tried with various BackgroundWorker combinations but that didn't help.

Also is there something equivqlent to a BeginUpdate()  / EndUpdate() to disable the refresh of the diagram while it is being updated?

Good day,

Processing is done in the current thread, which happens to be the UI thread if you call LoadFromFile from a menu-item event handler. You might try calling LoadFromString from a worker thread instead, but first disconnect the diagram from the view by assigning a new Diagram instance to the view' Diagram property, and assign back the loaded diagram once the Load method completes.

I hope that helps,
Stoyan
