[Solved] Binding RadGridView for Winforms error

[James]

I followed the video and typed the code as displayed:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)

        {

            AdventureWorksEntityDiagrams entities = new AdventureWorksEntityDiagrams();

            radGridView1.DataSource =entities.Products;

        }

    }

}

I get the following error:
The type initializer for 'TelerikBinding.AdventureWorksLTEntityDiagrams' threw an exception.

Any ideas why?

I am not using data services. I followed the example in your video. The project is very simple.

Add a Telerik OpenAccess Domain Model to project
Setup for Adventureworks
Drop a datagridview on form
Add following 2 lines of code to Form1_Load event
AdventureWorksEntityDiagrams entities = new AdventureWorksEntityDiagrams();
radGridView1.DataSource =entities.Products;

That's it.

Hi James,

I suspect that the connection string needed for your domain model is missing from the App.config file of the WinForms project. Could you please verify if this is the case and copy the appropriate connection string? If this is not the case, please send us the whole exception message, hopefully it would lead us to the problem.
