How do I make a marquee progress bar in WPF?

问题

In Winforms I could set the ProgressBarStyle of a progress bar to Marqee, and that would have the progress bar incriment on its own without having to be set, for processes where I don't know how long its going to take, and no good way to report back to the UI.

I would like to do the same in WPF, but I can't find a way to pull it off short of hosting a winform progress bar, which seems counter productive.

How can I pull this off in WPF? Do I have to host a winform progress bar?

回答1:

I think you simply want to set the IsIndeterminate property of the ProgressBar to true. (See this article, which also has a nice example of a fancy circular progress indicator.)

回答2:

Try the following

<ProgressBar 
  IsIndeterminate="True"
  Orientation="Horizontal" />

The key is the oddly named IsIndeterminate attribute. Setting this to true means Marque
