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

Install the CData ADO.NET Provider for SAP Fieldglass

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

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

Create a SAP Fieldglass-Connected Blazor App

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

1. Create a Blazor project on Visual Studio.
👁 Create a Blazor app project.

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.SAPFieldglass.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for SAP Fieldglass\lib etstandard2.0).
👁 Reference ADO.NET for SAP Fieldglass .dll in the Blazor app.

SELECT SAP Fieldglass Data from the Blazor App

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

   To authenticate, specify the Username, Password, APIKey, and EnvironmentURL connection properties.

   To obtain an APIKey, log in to the SAP API Business Hub and click on Get API Key.

   For example: EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH;

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

    @page "/"
    @using System.Data;
    @using System.Data.CData.SAPFieldglass;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (SAPFieldglassConnection connection = new SAPFieldglassConnection(
    "EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH;"))
    {
    var sql = "SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'";
    var results = new DataTable();
    
    SAPFieldglassDataAdapter dataAdapter = new SAPFieldglassDataAdapter(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 Fieldglass data as an HTML table in the Blazor app. 👁 Query SAP Fieldglass from Blazor app.
