We keep getting asked What’s the best practice way to suspend the SciChartSurface in a multi-pane stock chart demo.

We have multiple ways of doing this.

By far the most effective and thread-safe way to do this is to call SuspendUpdates directly on the SciChartSurface. But how to do this in a ViewModel?

I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”

However, there is only sample code on the provided github.

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

    Hi Andrew, Is there any way possible to bind SciChart instance through DI to ViewModel. I’m kind of stuck in between DI(Dagger2) and SciChart objects in VM through ISuspendable. With data-binding in Fragment & VM with constructor argument of ISuspendable is not possible ahead of time. Please suggest. Regards, Praween

    Wouldn’t it be easier to just have an attached property that can be bound to a view model which suspends updates if set to true? I know this doesn’t give the flexibility of having multiple disposable suspend locks, but that could be handled internally in the view model if really needed.
