Getting Started with WPF EntityFrameworkCoreDataSource

This article shows how to create a sample .NET application using RadEntityFrameworkCoreDataSource and RadGridView.

RadEntityFrameworkCoreDataSource is built on top of Entity Framework Core. It is recommended to familiarize yourself with the framework before going over this tutorial.

Creating the WPF .NET Application

Start Visual Studio 2019 (or newer), select "Create a new project" and choose WPF App (.NET Core).

Adding References

Before we get started, we will add the following NuGet packages.

  • Microsoft.EntityFrameworkCore
  • Microsoft.EntityFrameworkCore.SqlServer
  • Microsoft.EntityFrameworkCore.Tools

    The required Microsoft.EntityFrameworkCore version varies based on the target .NET version of the Telerik dlls.

    • .NET 6—EFCore version 6.0.9
    • .NET 7—EFCore version 7.0.0

We will also add the needed Telerik references.

  • Telerik.Windows.Controls
  • Telerik.Windows.Controls.Data
  • Telerik.Windows.Controls.EntityFrameworkCore
  • Telerik.Windows.Controls.GridView
  • Telerik.Windows.Controls.Input
  • Telerik.Windows.Data

Adding Telerik Assemblies Using NuGet

To use RadEntityFrameworkCoreDataSource when working with NuGet packages, install the Telerik.Windows.Controls.EntityFrameworkCore.for.Wpf.Xaml package. The package name may vary slightly based on the Telerik dlls set - Xaml or NoXaml

Xaml Usage

Example 1 demonstrates how you can set up the RadEntityFrameworkCoreDataSource and display data in a RadGridView. It assumes that you already have a DbContext named "MyEntityModel", which contains a DbSet called "Customers".

In case you don't have a DbContext/database setup, you can check out the MVVM Usage article, which shows how you can set them up from scratch.

Example 1: Defining RadEntityFrameworkCoreDataSource in xaml

<telerik:RadEntityFrameworkCoreDataSource Name="EntityFrameworkCoreDataSource" QueryName="Customers">  
<telerik:RadGridView ItemsSource="{Binding DataView, ElementName=EntityFrameworkCoreDataSource}"/> 


The RelatedObjects property of the RadEntityFrameworkCoreDataSource allows you to specify the names of the related entities that need to be retrieved. For example, if your main entity set is called "Customers", you might want to retrieve the "Orders" collection in case you want to get the related Orders for each Customer from the database. You can also specify several navigational property names separated by "/" characters and the control will use the ".ThenInclude()" method when retrieving them.

Example 2: Using the RelatedObjects

<telerik:RadEntityFrameworkCoreDataSource x:Name="coreDataSource" QueryName="Customers"> 
        <local:NorthwindContext />
