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

Install the CData ADO.NET Provider for Vault CRM

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

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

Create a Vault CRM-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for Vault CRM

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.VaultCRM.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Vault CRM\lib etstandard2.0).

SELECT Vault CRM Data from the Blazor App

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

   You are ready to connect after specifying the following connection properties:

   • Url: The host you see in the URL after you login to your account. For example: https://my-veeva-domain.veevavault.com
   • User: The username you use to login to your account.
   • Password: The password you use to login to your account.

   For example: User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;

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

         @page "/"
         @using System.Data;
         @using System.Data.CData.VaultCRM;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (VaultCRMConnection connection = new VaultCRMConnection(
                   "User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;"))
                 {
                     var sql = "SELECT ProductId, ProductName FROM NorthwindProducts WHERE CategoryId = 5";
                     var results = new DataTable();
         
                     VaultCRMDataAdapter dataAdapter = new VaultCRMDataAdapter(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 Vault CRM data as an HTML table in the Blazor app.

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