I'm starting my adventure with WPF and after creating my first application I want to style it a bit. I found UI template and using Blend for VS2013 I imported PSD into my project.
Here is how ProgressBar looks in PSD:
and here is what it looks when imported to Blend:
And here is code:

My problem is how can I convert that canvas to ProgressBar Template.
Based on tutorial I was able to create template, but there were rectangles not paths. I've tried using paths but I can't align them correctly.
How can I create Template that uses Path as PART_Track and PART_Indicator and how can I add text to that ProgressBar?
I imagine this as 3 layers: component background (orange one), progress background (brown) and progress bar (green). Maybe I should use two layers: progress bar and background with stroke?
This is my first template so I'd like to do it best I can.
I couldn't find similar question on SO (except snail progressbar, but there solution is based on images instead of paths).

I prepared a protoype of how your control template can be.
Firstly I have created a IMultiValueConverter defined as followed:
[ValueConversion(typeof(double), typeof(double))]
public class RatioConveter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return (System.Convert.ToDouble(values[0]) * System.Convert.ToDouble(values[1])) / System.Convert.ToDouble(values[2]);
}
public object[] ConvertBack(object value, Type[] targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotSupportedException();
}
}
Then I declared it as a resource in the wpf window (I omissis the declaration of the namespace):
<yourNamespace:RatioConveter x:Key="ratioConverter" />
Then I prepared a Style which applies the control template to all the ProgressBar in the window defined in this way:
<Style x:Key="{x:Type ProgressBar}"
TargetType="{x:Type ProgressBar}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Grid x:Name="Container" Height="{TemplateBinding Height}" Width="{TemplateBinding Width}">
<Canvas x:Name="Progress1" ClipToBounds="True" HorizontalAlignment="Left" Height="52" Width="493" UseLayoutRounding="False" VerticalAlignment="Top" Margin="0" >
<Canvas.Resources>
<system:Double x:Key="ratioConstant">1</system:Double>
</Canvas.Resources>

<ScaleTransform CenterX="0"

Note: The code may need some improvements but at least is a good start, the graphics when you reach low values in the progress bar doesn't seem to be very beautiful but surely you can improve the graphic of the control based in your needings. I hope this helps you.
