如何停止不确定的ProgressBar动画？

Question

I don't know if i'm missing some obvious method/property, but here it is: I have a ProgressBar, which has the property IsIndeterminate as true by default. But I want it's animation only in a certain period. How can I achieve that? I tried something like:

SomeBackgroundWorker.DoWork += SomeBackgroundWorker_DoWork;
pgbStatus.IsIndeterminate = true;
btnUpdate.IsEnabled = false;
SomeBackgroundWorker.RunWorkerAsync();
btnUpdate.IsEnabled = true;
pgbStatus.IsIndeterminate = false;

But then it wouldn't move. Sorry if it's a duplicate(I have the feeling it is), but I couldn't find the answer anywhere.

Place

btnUpdate.IsEnabled = true;
pgbStatus.IsIndeterminate = false;

In the end of SomeBackgroundWorker DoWork() method instead. Probably you will need Invoke() to UI thread also.
