Build MVC Applications with Connectivity to Raisers Edge NXT Data

In this article, we will guide you through the process of utilizing wizards within Visual Studio to seamlessly integrate the CData ADO.NET Provider for Raisers Edge NXT into a basic 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 MvcRaiserEdgeNXTApp.

2. If you are using Entity Framework 6, you will need to take the preliminary step of registering the Raisers Edge NXT 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 RaiserEdgeNXTModel.
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 Raisers Edge NXT Data Source in the dialog that is displayed.

6. Specify the required connection string properties.

   Before establishing a connection, supply the SubscriptionKey, found in the Blackbaud Raiser's Edge NXT Profile.

   Authenticating to Raiser's Edge NXT

   Blackbaud Raiser's Edge NXT uses the OAuth authentication standard. You can connect to without setting any connection properties using the embedded OAuth credentials.

   Alternatively, you can authenticate by creating a custom app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.

   See the Help documentation for an authentication guide.

   A typical connection string is below:

   SubscriptionKey=MySubscriptionKey;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;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 RaiserEdgeNXTEntities.

8. Select the views you need. In this example, Constituents 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

Once you've established the model and completed the project build, you can employ ASP.NET Scaffolding wizards to generate both 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, Constituents.
   • Data context class: Select your context class.
3. Leave the default values for the other fields.
