WPF Path : How to Draw this in XAML?

Question

I want to create a custom GroupBox with non rectangular header like in the following picture :

As you see, the content of the header must be parametrable, so image, title and background can be entered in xaml.

Thanks in advance.

Thank you for your answer.

Actually i want to use this design in a custom groupbox, so in your answer if i dont't set width and height of the grid (width=150 height =30) the shape components become separated, So i want the shape to be in a unique Body, so it will be easy to apply background colors. and by the way can you round corners like the following picture ?

Answer 1

Try this

  <Grid Width="150" Height="30">
    <Border CornerRadius="15,0,0,0" Background="SkyBlue" Height="30" Width="100" HorizontalAlignment="Left"></Border>                    
    <Path Data="M 100,0 L 150,40 L 100 40 Z" Fill="SkyBlue"></Path>
    <TextBlock Text="&#xE161;" FontFamily="Segoe Ui Symbol" Margin="10,0,0,0" FontSize="20" ></TextBlock>
    <TextBlock Text="Configuration" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock>
</Grid>

Explanation

I have used border as border has cornerRadius property.

<Border CornerRadius="15,0,0,0" Background="SkyBlue" Height="30" Width="100" HorizontalAlignment="Left">

And path data is

  <Path Data="M 100,0 L 150,40 L 100 40 Z" Fill="SkyBlue"></Path>

Using coordinate system ,i have use started point M 100,0 as border with is 100 and i used 40 for path height in data and 150 for grid total grid width. and Z used for close path data.

Final Output

Update You can use viewbox to scale this drawing as per requrement and i have added rounded curve also
