Build MVC Applications with Connectivity to Sage 200 Data

This article shows how to use only the Entity Framework and the CData ADO.NET provider to access Sage 200 from an ASP.NET MVC application.

This article shows how to use wizards in Visual Studio to drop the CData ADO.NET Provider for Sage 200 into a simple MVC (model, view, controller) project.

Create the Entity Framework Model

Follow the steps below to save connection properties and map tables to entities in the data model.

  1. Create a new MVC project in Visual Studio. In this example, the project name is MvcSage200App.
  2. If you are using Entity Framework 6, you will need to take the preliminary step of registering the Sage 200 Entity Framework provider for your project. See the "LINQ and Entity Framework" chapter in the help documentation for a guide.

    Note that MVC 3 scaffolding and MVC 4 scaffolding do not support Entity Framework 6. You can use your scaffolding with Entity Framework 6 by upgrading to the latest version of MVC.

  3. To add the .edmx file from the designer, right-click your Models folder and click Add New Item. Select ADO.NET Entity Data Model, name the model, and click Add. In this example, the name of the model is Sage200Model.
  4. In the Entity Data Model wizard, select the option 'EF Designer from database'. The Entity Data Model wizard is displayed.
  5. Click New Connection. Select CData Sage 200 Data Source in the dialog that is displayed.
  6. Specify the required connection string properties.

    • Schema: Determines which Sage 200 edition you are connecting to. Specify either StandardUK or ProfessionalUK.
    • Subscription Key: Provides access to the APIs that are used to establish a connection. You will first need to log into the Sage 200 API website and subscribe to the API edition that matches your account. You can do so here: https://developer.columbus.sage.com/docs/services/api/uk. Afterwards, the subscription key may be found in your profile after logging into Sage 200.

    A typical connection string is below:

    SubscriptionKey=12345;Schema=StandardUK;InitiateOAuth=GETANDREFRESH
  7. Name the connection and select whether to include sensitive information, such as connection credentials, in the connection string. For simplicity, this example saves sensitive information in Web.config. The connection settings are saved as Sage200Entities.

  8. Select the views you need. In this example, Banks is imported. Also, the option to pluralize object names is deselected in this example. Click Finish to create the .edmx file.
  9. Build your project to complete this step.

Scaffold the Controller and Views

After creating the model and building the project, you can use ASP.NET Scaffolding wizards to create the controller and the views.

  1. In Solution Explorer, right-click the controllers folder and click Add -> Controller. Select MVC 5 Controller with views, using Entity Framework.
  2. In the Add Controller dialog that is then displayed, select the following options:

    • Model class: Select a table you imported; for example, Banks.
    • Data context class: Select your context class.
  3. Leave the default values for the other fields.

You can now access the list of Banks records at http://MySite/Banks. With every state change the site picks up any data changes.
