How do you show progress when IsIndeterminate=“True” in a WPF progress bar?

Question

This has to be the simplest question of all, but I cannot seem to figure it out. I have the progress bar in place. How do I make it show progress? How do I start the thing?<

Answer 1

This is no real difference than @dyslexicanaboko above, but it is quick and easy to do for a demonstration you can control:

In XAML:

In code behind:

Public Sub StartAProcess()
  pBar1.IsIndeterminate = True
End Sub

Public Sub StopAProcess()
  pBar1.IsIndeterminate = False
End Sub

Upon clicking the Start Process button the animation will start and continue until the Stop Process button is clicked. It should be obvious, but the IsIndeterminate option is not good UI practice; better to actually update the value, but for those who want to see this in action...
