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

Install the CData ADO.NET Provider for Reckon Accounts Hosted

CData ADO.NET Providers allow users to access Reckon Accounts Hosted just like they would access SQL Server, using simple SQL queries.

Install the Reckon Accounts Hosted ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Reckon Accounts Hosted ADO.NET Data Provider."

Create a Reckon Accounts Hosted-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for Reckon Accounts Hosted

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.ReckonAccountsHosted.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Reckon Accounts Hosted\lib etstandard2.0).
👁 Reference ADO.NET for Reckon Accounts Hosted .dll in the Blazor app.

SELECT Reckon Accounts Hosted Data from the Blazor App

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

   The connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

   • SubscriptionKey: Required. You get this value when you created your developer account.
   • CountryVersion: Defaults to 2021.R2.AU.
   • CompanyFile: Required. The path to the company file.
   • User: Required. The username of the company file.
   • Password: Required. The password of the company file.
   • InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
   • CallbackURL: The redirectURI of your Custom OAuth App.
   • OAuthClientId: The client id of your Custom OAuth App.
   • OAuthClientSecret: The client secret of your Custom OAuth App.

   CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

   For example: SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;

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

    @page "/"
    @using System.Data;
    @using System.Data.CData.ReckonAccountsHosted;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(
    "SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;"))
    {
    var sql = "SELECT Name, Balance FROM Accounts WHERE IsActive = 'true'";
    var results = new DataTable();
    
    ReckonAccountsHostedDataAdapter dataAdapter = new ReckonAccountsHostedDataAdapter(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 Reckon Accounts Hosted data as an HTML table in the Blazor app. 👁 Query Reckon Accounts Hosted from Blazor app.
