Unable to reset ProgressBar

Question

I am experimenting a behavior which makes me crazy.

I have a ProgressBar which represents the evolution of an import in database (in percents, from 0 to 100).

After the import is done (ProgressBar.Value = 100.0), I open a log window with a code which looks like this :

RadWindow window = new RadWindow()
{
    //Set some properties
};
window.Closed += Log_Closed;
window.ShowDialog();

After the RadWindow is closed, I want to reset the ProgressBar. As you can see I use the function Log_Closed whose code is bellow :

private void Log_Closed(object sender, EventArgs e)
{
    //pbImport.Value = pbImport.Minimum; (didn't work)
    pbImport.Value = 0;
}

Note : pbImport is my progress bar.

The instruction in Log_Closed has no effect.

Obviously, the progress bar is not updated in UI. I can't understand this. Thank you for your help.

Animations hold onto properties, in order to reset them in code, you have to remove the animation first so that the property is "released".

See https://msdn.microsoft.com/en-us/library/aa970493%28v=vs.110%29.aspx for information on how to set a property after an animation in WPF.
