Connect to Sage 200 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 Sage 200 can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Sage 200 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 Sage 200 using standard SQL queries.

Install the CData ADO.NET Provider for Sage 200

CData ADO.NET Providers allow users to access Sage 200 just like they would access SQL Server, using simple SQL queries.

Install the Sage 200 ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Sage 200 ADO.NET Data Provider."

Create a Sage 200-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for Sage 200

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.Sage200.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Sage 200\lib etstandard2.0).

SELECT Sage 200 Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a Sage200Connection object, set the connection string:
   • 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.

   For example: SubscriptionKey=12345;Schema=StandardUK;

3. The code below creates a simple Blazor app for displaying Sage 200 data, using standard SQL to query Sage 200 just like SQL Server.

         @page "/"
         @using System.Data;
         @using System.Data.CData.Sage200;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (Sage200Connection connection = new Sage200Connection(
                   "SubscriptionKey=12345;Schema=StandardUK;"))
                 {
                     var sql = "SELECT Id, Code FROM Banks WHERE Code = '12345'";
                     var results = new DataTable();
         
                     Sage200DataAdapter dataAdapter = new Sage200DataAdapter(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 Sage 200 data as an HTML table in the Blazor app.

   At this point, you have a Sage 200-connected Blazor app, capable of working with live Sage 200 data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live Sage 200 data in your Blazor apps today.
