How to use Winforms Modern UI Metro Framework in C#

To use the Winforms Modern UI Metro Framework in C#, you'll need to follow these steps:

Right click on your project select Manage NuGet Packages -> Search metro framework -> Install

If you don't see the metro framework in your Visual Studio toolbox, you can view How to download and install metro framework

We will create a simple dashboard in c# windows forms application using the Metro Framework library.

To create a metro form, you need to open the form in which you want to use the Metro Framework, at the top of your code file to import the MetroFramework namespaces, then change inherit your form to MetroForm instead of Form.

You can design your form as below

Next, Create a metro user control named ucCategory, then drag and drop a MetroGridView from the Visual Studio toolbox onto your metro user control.

ucCategory

Do the same way for product user control.

ucProduct

Finaly, Create a dashboard metro form, then drag and drop MetroTitle control from Visual Studio toolbox onto your metro from.

ucDashboard

I will use Entity Framework to retrive data from sql database, so you need to create an ADO.NET Entity Data Model

Right click on your project select Add -> New Item -> ADO.NET Entity Data Model -> Select Northwind database -> Category, Product table

If you haven't got Northwind database, you can view How to download and restore Northwind database in SQL Server

Open your main form, then add code to handle your winform as below
