C# Class mGitHub.SampleApp.Views.ProgressBar.PerformanceProgressBar

A progress bar implementation for a smoother appearance of the indeterminate states, with the added behavior that after the behavior is no longer needed, it waits until the animation completes.

Important - this control is not really designed or tested for regular progress bar use, but only indeterminate. As a result, IsIndeterminate is in the default style. Use the determinate version at your own risk as there are no benefits to this over the standard progress bar in that situation.

Inheritance: System.Windows.Controls.ProgressBar

Public Methods

Method	Description
OnApplyTemplate ( ) : void	Overrides the template application stage so that the storyboard can be retrieved from the implementation root.
PerformanceProgressBar ( ) : System	Initializes a new instance of the PerformanceProgressBar type.

Protected Methods

Method	Description
OnIndeterminateStoryboardCompleted ( object sender, EventArgs e ) : void	Hooks up to the Completed event of the indeterminate storyboard. For technical reasons, when a storyboard has a repeat behavior of 'Forever', this means the Completed event is never called. So this method needs to either 1) restart the storyboard animation again or 2) if the indeterminate behavior is finished, not restart the animation and update the underlying bound state.
