Connect to Anaplan Data from Blazor Apps

Blazor is a framework for developing modern, client-side web UIs using .NET technology. Instead of coding in JavaScript, developers can use the familiar C# language and .NET libraries to build app UIs.

The CData ADO.NET Provider for Anaplan can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Anaplan data. Since Blazor supports .NET Core, developers can use CData ADO.NET Providers in Blazor apps. In this article, we will guide you to build a simple Blazor app that talks to Anaplan using standard SQL queries.

Install the CData ADO.NET Provider for Anaplan

CData ADO.NET Providers allow users to access Anaplan just like they would access SQL Server, using simple SQL queries.

Install the Anaplan ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Anaplan ADO.NET Data Provider."

Create a Anaplan-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for Anaplan

1. Create a Blazor project on Visual Studio.

2. From the Solution Explorer, right click Dependencies, then click Add Project Reference.
3. In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.Anaplan.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Anaplan\lib etstandard2.0).

SELECT Anaplan Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a AnaplanConnection object, set the connection string:

   Authenticating to Anaplan

   The driver supports authenticating with Basic, Certificate, or OAuth. In every case, set Region to the region where your Anaplan account data is hosted (e.g., US1, which is the default).

   Using Basic Authentication

   Set AuthScheme to Basic, then supply your Anaplan User and Password. If your workspace uses single sign-on (SSO), you must be assigned as an Exception User to use Basic authentication.

   Using Certificate Authentication

   Set AuthScheme to Certificate, then supply the Certificate, CertificateType, and PrivateKey properties (and the matching CertificatePassword / PrivateKeyPassword if either is encrypted). The certificate must be a CA-issued X.509 certificate registered with your Anaplan tenant administrator.

   Using OAuth Authentication

   Register a custom OAuth application in Anaplan, then set the following properties:

   • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
   • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
   • CallbackURL: The redirect URI defined when you registered your application.
   • InitiateOAuth: Set to GETANDREFRESH to have the driver manage the OAuth token exchange and refresh automatically.

   See the Getting Started chapter of the help documentation for a guide to creating a custom OAuth app and using OAuth.

   For example: OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=your_callback_url;Region=US1;InitiateOAuth=GETANDREFRESH;

3. The code below creates a simple Blazor app for displaying Anaplan data, using standard SQL to query Anaplan just like SQL Server.

         @page "/"
         @using System.Data;
         @using System.Data.CData.Anaplan;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (AnaplanConnection connection = new AnaplanConnection(
                   "OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackURL=your_callback_url;Region=US1;InitiateOAuth=GETANDREFRESH;"))
                 {
                     var sql = "SELECT Region, Product FROM [Workspace].[Model].[Sales] WHERE Value = '100'";
                     var results = new DataTable();
         
                     AnaplanDataAdapter dataAdapter = new AnaplanDataAdapter(sql, connection);
                     dataAdapter.Fill(results);
         
                     <table class="table table-bordered">
                         <thead class="thead-light">
                             <tr>
                                 @foreach (DataColumn item in results.Rows[0].Table.Columns)
                                 {
                                     <th scope="col">@item.ColumnName</th>
                                 }
                             </tr>
                         </thead>
                         <tbody>
                             @foreach (DataRow row in results.Rows)
                             {
                                 <tr>
                                     @foreach (var column in row.ItemArray)
                                     {
                                         <td>@column.ToString()</td>
                                     }
                                 </tr>
                             }
                         </tbody>
                     </table>
                 }
             </div>
         </div>
       

4. Rebuild and run the project. The ADO.NET Provider renders Anaplan data as an HTML table in the Blazor app.

   At this point, you have a Anaplan-connected Blazor app, capable of working with live Anaplan data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live Anaplan data in your Blazor apps today.
