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?

<ProgressBar x:Name="ProgressUpload" Margin="5" IsIndeterminate="True" ></ProgressBar>

Answer 1

A possible workaround of the problem is to simply show or hide the ProgressBar control:

progressBar.Visibility = Visibility.Visible;

progressBar.Visibility = Visibility.Collapsed;

Answer 2

If you set IsIndeterminate to True, the progress has the meaning that something is in progress but you cannot determine the exact duration. So, I can only tell you to set it to false and to use the progress bar in its "standard" behavior.
