How do you show progress when Indeterminate="True" in a WPF Progress bar?

Question

This has to be the simplest of all questions, but I can not 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

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.
