Getting Started with Blazor Tooltip Component in Blazor Web App

24 Jun 20267 minutes to read

This section briefly explains about how to include Blazor Tooltip component in your Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Create a new Blazor Web App

Create a Blazor Web App using Visual Studio via Microsoft Templates or the Blazor Extension. For detailed instructions, refer to the Blazor Web App Getting Started documentation.

Run the following command to create a new Blazor Web App.

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Alternatively, create a Blazor Web App using Visual Studio Code via Microsoft Templates, the Blazor Extension, or the C# Dev Kit extension.

Run the following command to create a new Blazor Web App.

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

Install the required Blazor packages

Install Syncfusion.Blazor.Popups and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details. If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the .Client project.

  1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
  2. Search the required NuGet packages (Syncfusion.Blazor.Popups and Syncfusion.Blazor.Themes) and install them.

Alternatively, you can install the same packages using the Package Manager Console with the following commands.

Install-Package Syncfusion.Blazor.Popups -Version 33.2.3
Install-Package Syncfusion.Blazor.Themes -Version 33.2.3

Open the terminal and run the following commands.

dotnet add package Syncfusion.Blazor.Popups -v 33.2.3
dotnet add package Syncfusion.Blazor.Themes -v 33.2.3

Open the command prompt and run the following commands.

dotnet add package Syncfusion.Blazor.Popups -v 33.2.3
dotnet add package Syncfusion.Blazor.Themes -v 33.2.3

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file in the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.Popups namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Popups

Register the Blazor service

Open the Program.cs file in Blazor Web App and register the Blazor service. If the Interactive Render Mode is set to WebAssembly or Auto, register the Blazor service in Program.cs files of both the server and client projects in 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 and script references in the App.razor file.

...
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
...
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

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 Blazor Tooltip component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor Tooltip component inside the razor file.

NOTE

If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto). If the Interactivity is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

@rendermode InteractiveAuto

@using Syncfusion.Blazor.Popups
@using Syncfusion.Blazor.Buttons

<SfTooltip ID="Tooltip" Target="#btn" Content="@Content">
    <SfButton ID="btn" Content="Show Tooltip"></SfButton>
</SfTooltip>

@code
{
    string Content = "Lets go green & Save Earth !!";
}

Run the application

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor Tooltip component will render in your default web browser.

Open the terminal and navigate to the main project folder (for example, BlazorWebApp) and run the following command.

cd ..
cd BlazorWebApp
dotnet run

Open the command prompt and navigate to the main project folder (for example, BlazorWebApp) and run the following command.

cd ..
cd BlazorWebApp
dotnet run
Blazor Tooltip Component

NOTE

The Tooltip component in our system uses the HTML element’s id or class name to identify the target for the tooltip. However, when using a GUID as the target ID, it is not able to recognize IDs that start with a digit.
