Incorrect colors in WPF Progress Bar

Question

EDIT: I solved my problem ... take a look at my answer. It is right if it is wrong. Thanks.

Question: For some reason, it seems that the progress bar in a WPF application does not show the required color.

Here is the XAML code:

<Window x:Class="TaskbarProgressApp.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.TaskbarItemInfo> <TaskbarItemInfo /> </Window.TaskbarItemInfo> <Grid> <ProgressBar x:Name="ProgressBar" Margin="10" HorizontalAlignment="Stretch" VerticalAlignment="Center" Height="23" Background="{x:Null}" Foreground="DarkRed"> </ProgressBar> </Grid> </Window> 

Here is the result:

Not like Dark Red for me ... happens with every color :(

Any thoughts?

Answer 1

Thanks to @Merlyn Morgan-Graham and @CharithJ for pointing out another question, I thought it was something completely different when I read it.

I solved the problem and I would like to share it.

I downloaded the trial version of MS Expression Blend and changed:

 <Trigger Property="IsIndeterminate" Value="false"> <Setter Property="Background" TargetName="Animation" Value="#80B5FFA9"/> </Trigger> 

For

 <Trigger Property="IsIndeterminate" Value="false"> <Setter Property="Background" TargetName="Animation" Value="#00000000"/> </Trigger> 

It gives colors like these:

Dark red:

Even it works

 <Trigger Property="IsIndeterminate" Value="true"> <Setter Property="Background" TargetName="Animation" Value="#80B5FFA9"/> </Trigger> 

The progress bar does not change, but the colors are as they should be.

It is sad that there is no way to change it directly.

Thanks for the help.

You can do this by changing the control template. Here is an article on that of MSDN. ProgressBar Checklist Example
