Build ASP.NET Core Blazor C# apps that integrate with real-time Drift data using standard SQL.
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 Drift 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 Drift using standard SQL queries.
Install the CData API Driver for ADO.NET
CData ADO.NET Providers allow users to access Drift just like they would access SQL Server, using simple SQL queries.
Install the Drift ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Drift ADO.NET Data Provider."
Create a Drift-Connected Blazor App
Start by creating a Blazor project that references the CData API Driver for ADO.NET
- Create a Blazor project on Visual Studio.
- From the Solution Explorer, right click Dependencies, then click Add Project Reference.
- 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).
SELECT Drift Data from the Blazor App
- Open the Index.razor file from the Project page.
- In a APIConnection object, set the connection string:
Start by setting the Profile connection property to the location of the Drift Profile on disk (e.g. C:\profiles\Drift.apip). Next, set the ProfileSettings connection property to the connection string for Drift (see below).
Drift API Profile Settings
Drift uses OAuth-based authentication.
You must first register an application here: https://dev.drift.com. Your app will be assigned a client ID and a client secret. Set these in your connection string via the OAuthClientId and OAuthClientSecret properties. More information on setting up an OAuth application can be found at https://devdocs.drift.com/docs/.
After setting the following options in the ProfileSettings connection property, you are ready to connect:
- AuthScheme: Set this to OAuth.
- OAuthClientId: Set this to the Client Id that is specified in your app settings.
- OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
For example: Profile=C:\profiles\Drift.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;
- The code below creates a simple Blazor app for displaying Drift data, using standard SQL to query Drift 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\Drift.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;")) { var sql = "SELECT Id, DisplayName FROM Contacts WHERE LastName = 'Stark'"; 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>
- Rebuild and run the project. The ADO.NET Provider renders Drift data as an HTML table in the Blazor app.
At this point, you have a Drift-connected Blazor app, capable of working with live Drift data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live Drift data in your Blazor apps today.
