Creating Metro Style Circle Button Using Mahapps Metro UI Framework

In this article, I will explain how to create Metro style Circle Button in WPF application using Mahapps Metro UI framework and Microsoft Visual Studio.

Step 1

For installation of Metro UI framework, please check my previous blog.
Step 2

Create a new button in MainWindow, like Image 1.



I have added three buttons in this project. You can add these from ToolBox.

Step 3

We have to install the Icon Resource package for control customization using below command, because MahApps.Metro does not embed any Icons Package.

Install-Package MahApps.Metro.Resources

For installation of MahApps.Metro.Resources, click TOOLS - NuGet Package Manager - Package Manager Console.



Enter the above command in Package Manager Console, then hit the Enter button.

After a few seconds, you will get an installation completion message.



Step 4

Add the blow ResourceDictionary in App.xaml file.
  1. <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />   
  2. <ResourceDictionary Source="/Resources/Icons.xaml" />   


Step 5

Add the below code into button opening tag.
  1. <Rectangle Width="20" Height="20" Fill="{Binding Foreground, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Button}}}">   
  2. <Rectangle.OpacityMask>   
  3. <VisualBrush Stretch="Fill" Visual="{StaticResource appbar_disk}" />   
  4. </Rectangle.OpacityMask>   
  5. </Rectangle>   


I have applied the same logic for all the three buttons. You can use it for remaining buttons.

You can change the button icon from Visual Property through applying static resources.
