Connect to SAP Hybris C4C 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 Hybris C4C can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live SAP Hybris C4C 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 Hybris C4C using standard SQL queries.

Install the CData ADO.NET Provider for SAP Hybris C4C

CData ADO.NET Providers allow users to access SAP Hybris C4C just like they would access SQL Server, using simple SQL queries.

Install the SAP Hybris C4C ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "SAP Hybris C4C ADO.NET Data Provider."

Create a SAP Hybris C4C-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for SAP Hybris C4C

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.SAPHybrisC4C.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for SAP Hybris C4C\lib etstandard2.0).

SELECT SAP Hybris C4C Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a SAPHybrisC4CConnection object, set the connection string:

   SAP Hybris Cloud for Customer uses basic authentication. Set the User and Password to your login credentials.

   For example: User=user;Password=password;

3. The code below creates a simple Blazor app for displaying SAP Hybris C4C data, using standard SQL to query SAP Hybris C4C just like SQL Server.

         @page "/"
         @using System.Data;
         @using System.Data.CData.SAPHybrisC4C;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (SAPHybrisC4CConnection connection = new SAPHybrisC4CConnection(
                   "User=user;Password=password;"))
                 {
                     var sql = "SELECT ObjectID, AccountName FROM AccountCollection";
                     var results = new DataTable();
         
                     SAPHybrisC4CDataAdapter dataAdapter = new SAPHybrisC4CDataAdapter(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 Hybris C4C data as an HTML table in the Blazor app.

   At this point, you have a SAP Hybris C4C-connected Blazor app, capable of working with live SAP Hybris C4C data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live SAP Hybris C4C data in your Blazor apps today.
