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

Install the CData ADO.NET Provider for SAP Business One

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

Install the SAP Business One ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "SAP Business One ADO.NET Data Provider."

Create a SAP Business One-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for SAP Business One

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.SAPBusinessOne.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for SAP Business One\lib etstandard2.0).

SELECT SAP Business One Data from the Blazor App

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

   To authenticate to SAP Business One you must provide the Userand Passwordproperties.

   To connect to data, specify Url. This is your SAP Business One Service Layer root URL.

   For example: Url=http://localhost:50000/b1s/v1;User=username;Password=password;CompanyDB=dbname;

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

         @page "/"
         @using System.Data;
         @using System.Data.CData.SAPBusinessOne;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (SAPBusinessOneConnection connection = new SAPBusinessOneConnection(
                   "Url=http://localhost:50000/b1s/v1;User=username;Password=password;CompanyDB=dbname;"))
                 {
                     var sql = "SELECT DocEntry, DocType FROM Orders";
                     var results = new DataTable();
         
                     SAPBusinessOneDataAdapter dataAdapter = new SAPBusinessOneDataAdapter(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 SAP Business One data as an HTML table in the Blazor app.

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