Using TaskBarItemInfo in WPF for the progress bar in the Win 7 taskbar

Question

Does anyone have a WPF example of updating ProgressState through available enumeration states when moving through ProgressValue?

I have the following code that binds my run value to run from 0 to 1:

<Window.TaskbarItemInfo>
    <TaskbarItemInfo Description="An app with a taskbar info description" 
                     ProgressValue="{Binding Count}" ProgressState="Normal"/>
</Window.TaskbarItemInfo>

But, what is a good way to switch from No to Normal to No or other threads: No-Normal- Suspended-Normal-None . In the above code, the progress bar on the left is displayed at 0%, and then ends at 100% (1). I suppose I could associate this with a converter for another property hanging in my ViewModel, but wanted to see if anyone had any slicker solutions.

Thank!

ProgressValue - double use a value from 0 to 1

Just like you bind ProgressValue, you can also bind ProgressState. The ProgressState type is an enumeration called TaskbarItemProgressState that includes the states that you have already mentioned.

public enum TaskbarItemProgressState
{
    // Summary:
    //     No progress indicator is displayed in the taskbar button.
    None = 0,
    //
    // Summary:
    //     A pulsing green indicator is displayed in the taskbar button.
    Indeterminate = 1,
    //
    // Summary:
    //     A green progress indicator is displayed in the taskbar button.
    Normal = 2,
    //
    // Summary:
    //     A red progress indicator is displayed in the taskbar button.
    Error = 3,
    //
    // Summary:
    //     A yellow progress indicator is displayed in the taskbar button.
    Paused = 4,
}

I think that the “weakest” ways to do this are the methods you already mentioned, either using a converter or manually
