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

Install the CData ADO.NET Provider for Sage Cloud Accounting

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

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

Create a Sage Cloud Accounting-Connected Blazor App

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

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.SageBCAccounting.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Sage Cloud Accounting\lib etstandard2.0).
👁 Reference ADO.NET for Sage Cloud Accounting .dll in the Blazor app.

SELECT Sage Cloud Accounting Data from the Blazor App

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

   You can connect to Sage Business Cloud Accounting using the embedded OAuth connectivity. When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

   For example: InitiateOAuth=GETANDREFRESH;

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

    @page "/"
    @using System.Data;
    @using System.Data.CData.SageBCAccounting;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (SageBCAccountingConnection connection = new SageBCAccountingConnection(
    "InitiateOAuth=GETANDREFRESH;"))
    {
    var sql = "SELECT contact_name, total_amount FROM SalesInvoices WHERE sent = 'TRUE'";
    var results = new DataTable();
    
    SageBCAccountingDataAdapter dataAdapter = new SageBCAccountingDataAdapter(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 Cloud Accounting data as an HTML table in the Blazor app. 👁 Query Sage Cloud Accounting from Blazor app.
