component in your Blazor Web App using Visual Studio.
Prerequisites
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.
You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.
Install Syncfusion Blazor Inputs and Themes NuGet in the App
To add Blazor Rating 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.Inputs and Syncfusion.Blazor.Themes.
If you utilize WebAssembly or Auto
render modes in the Blazor Web App need to be install Syncfusion Blazor components NuGet packages within the client project.
Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.Inputs -Version 27.1.48
Install-Package Syncfusion.Blazor.Themes -Version 27.1.48
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.Inputs
namespace .
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Inputs
Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Web App.
If you select an Interactive render mode as WebAssembly
or Auto
, you need to register the Syncfusion Blazor service in both ~/Program.cs files of your Blazor Web App.
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....
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/bootstrap5.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 Rating component
Add the Syncfusion Blazor Rating component in the ~Pages/.razor file. If an interactivity location as Per page/component
in the web app, define a render mode at the top of the ~Pages/.razor
component, as follows:
