Connect to JobNimbus 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 API Driver for ADO.NET can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live JobNimbus 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 JobNimbus using standard SQL queries.

Install the CData API Driver for ADO.NET

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

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

Create a JobNimbus-Connected Blazor App

Start by creating a Blazor project that references the CData API Driver for ADO.NET

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.API.dll, typically located at C:\Program Files\CData\CData API Driver for ADO.NET\lib etstandard2.0).
👁 Reference ADO.NET for JobNimbus .dll in the Blazor app.

SELECT JobNimbus Data from the Blazor App

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

   Using API Key Authentication

   JobNimbus uses API key authentication to control access to the API. To obtain a JobNimbus API key:

   1. Log in to your JobNimbus account.
   2. Navigate to Settings > Integrations > API.
   3. Generate or copy your existing API key from this page.

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   Set the following in the ProfileSettings connection property:
   • APIKey: Set this to your JobNimbus API key.

   Example Connection String

   Profile=C:\profiles\JobNimbus.apip;AuthScheme=APIKey;ProfileSettings='APIKey=my_api_key';
   

   For example: Profile=C:\profiles\JobNimbus.apip;AuthScheme=APIKey;ProfileSettings='APIKey=my_api_key';

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

    @page "/"
    @using System.Data;
    @using System.Data.CData.API;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (APIConnection connection = new APIConnection(
    "Profile=C:\profiles\JobNimbus.apip;AuthScheme=APIKey;ProfileSettings='APIKey=my_api_key';"))
    {
    var sql = "SELECT , FROM AccountUsers WHERE = ''";
    var results = new DataTable();
    
    APIDataAdapter dataAdapter = new APIDataAdapter(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 JobNimbus data as an HTML table in the Blazor app. 👁 Query JobNimbus from Blazor app.
   

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