29 Nov 20245 minutes to read

This section briefly explains about how to include Blazor Smart TextArea component in your Blazor Web App using Visual Studio.

Prerequisites

NOTE

Syncfusion® Blazor Smart Components are compatible with both OpenAI and Azure OpenAI, and fully support Server Interactivity mode apps.

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.

Install Syncfusion® Blazor SmartComponents and Themes NuGet in the App

To add Blazor Smart TextArea component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.SmartComponents and Syncfusion.Blazor.Themes.

Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.SmartComponents -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion® Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.SmartComponents namespace .

@using Syncfusion.Blazor
@using Syncfusion.Blazor.SmartComponents

Now, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App.

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....

Configure AI Service

To configure the AI service, add the following settings to the ~/Program.cs file in your Blazor Server app.

using Syncfusion.Blazor.SmartComponents;
var builder = WebApplication.CreateBuilder(args);

....

builder.Services.AddSyncfusionBlazor();

string apiKey = "api-key";
string deploymentName = "deployment-name";
string endpoint = "end point url";

builder.Services.AddSyncfusionSmartComponents()
.ConfigureCredentials(new AIServiceCredentials(apiKey, deploymentName, endpoint))
.InjectOpenAIInference();

var app = builder.Build();
....

Here,

  • apiKey: “OpenAI or Azure OpenAI API Key”;
  • deploymentName: “Azure OpenAI deployment name”;
  • endpoint: “Azure OpenAI deployment end point URL”;

For Azure OpenAI, first deploy an Azure OpenAI Service resource and model, then values for apiKey, deploymentName and endpoint will all be provided to you.

If you are using OpenAI, create an API key and place it at apiKey, leave the endpoint as "". The value for deploymentName is the model you wish to use (e.g., gpt-3.5-turbo, gpt-4, etc.).

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/tailwind.css" rel="stylesheet" />
</head>

<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion® Blazor Smart TextArea component

Add the Syncfusion® Blazor Smart TextArea component in the ~Pages/Index.razor file.

<SfSmartTextArea UserRole="@userRole" UserPhrases="@userPhrases" Placeholder="Enter your queries here" @bind-Value="prompt" Width="75%" RowCount="5">
</SfSmartTextArea>

@code {
    private string? prompt;
    public string userRole = "Maintainer of an open-source project replying to GitHub issues";
    public string[] userPhrases = [
        "Thank you for contacting us.",
        "To investigate, We will need a reproducible example as a public Git repository.",
        "Could you please post a screenshot of NEED_INFO?",
        "This sounds like a usage question. This issue tracker is intended for bugs and feature proposals. Unfortunately, we don't have the capacity to answer general usage questions and would recommend StackOverflow for a faster response.",
        "We do not accept ZIP files as reproducible examples.",
        "Bug report: File not found error occurred in NEED_INFO"
    ];
}

Here,

UserRole: This attribute is required to defines the context of the autocompletion based on the role of the person typing.
UserPhrases: This attribute is optional to provides predefined expressions that align with User/application’s tone and frequently used content.

  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Smart TextArea component in your default web browser.

  • Type ‘To investigate’ to experience instant sentence autocompletion.
