Question

I have a progress bar in WPF, I set a storyboard animation to it from 0-90 fillup over x period of time which may change based on the task that is being performed.

Would it be possible to allow its storyboard animation to play out in a different thread then interject into it to change various properties of the progress bar when needed?

Per Laurent’s comment …

void startProgress()
{
    ThreadStart ts = new ThreadStart(Go);
    Thread t = new Thread(ts);
    t.Start();
}

void Go()
{
    double val = 0;
    while (val < 100)
    {
        Thread.Sleep(50);
        Dispatcher.Invoke(new action(() =>
        {
            MyProgressBar.Value += 0.5;
            val = MyProgressBar.Value;
        }));
    }
}

delegate void action();
