Getting started with Blazor Tooltip component

This section briefly explains how to include a Tooltip in your Blazor Server-Side application. Refer to the Getting Started with Syncfusion Blazor for Server-Side in Visual Studio 2019 page for the introduction and configuring the common specifications.

Importing Syncfusion Blazor component in the application

Install Syncfusion.Blazor NuGet package to the application by using the NuGet Package Manager.

Note: Please ensure to check the Include prerelease option for our Beta release.
You can add the client-side style resources using NuGet package to the <head> element of the ~/wwwroot/index.html page in Blazor WebAssembly app or ~/Pages/_Host.cshtml page in Blazor Server app.

Note: You can also add the client-side style resources through CDN.

    <head>
        ....
        ....
        <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
    </head>

    <head>
        <link href="https://cdn.syncfusion.com/blazor/18.1.55/styles/bootstrap4.css" rel="stylesheet" />
    </head>

For Internet Explorer 11 kindly refer the polyfills. Refer the documentation for more information.

<head>
    <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
    <script src="https://github.com/Daddoon/Blazor.Polyfill/releases/download/3.0.1/blazor.polyfill.min.js"></script>
</head>

Add Syncfusion Blazor service in Startup.cs (Server-side application)

Open the Startup.cs file and add services required by Syncfusion components using services.AddSyncfusionBlazor() method. Add this method in the ConfigureServices function as follows.

using Syncfusion.Blazor;

namespace BlazorApplication
{
    public class Startup
    {
        ....
        ....
        public void ConfigureServices(IServiceCollection services)
        {
            ....
            ....
            services.AddSyncfusionBlazor();
        }
    }
}

Add Syncfusion Blazor service in Program.cs (Client-side application)

Open the Program.cs file and add services required by Syncfusion components using builder.services.AddSyncfusionBlazor() method. Add this method in the Main function as follows.

using Syncfusion.Blazor;

namespace BlazorApplication
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            ....
            builder.Services.AddSyncfusionBlazor();
        }
    }
}

Note: To enable custom client side resource loading from CRG or CDN. You need to disable resource loading by AddSyncfusionBlazor(true) and load the scripts to the <head> element of the ~/wwwroot/index.html page in Blazor WebAssembly app or ~/Pages/_Host.cshtml page in Blazor Server app.

    <head>
        <script src="https://cdn.syncfusion.com/blazor/18.1.55/syncfusion-blazor.min.js"></script>
    </head>

Adding component package to the application

Open ~/_Imports.razor file and import the Syncfusion.Blazor.Popups package.

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

Now, add the Syncfusion Blazor Tooltip component in any web page razor in the Pages folder. For example, the Tooltip component is added in the ~/Pages/Index.razor page.

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

<SfTooltip ID="Tooltip" Target="#btn">
    <TooltipTemplates>
        <Content>
            Lets go green & Save Earth !!
        </Content>
    </TooltipTemplates>
    <SfButton ID="btn" Content="Show Tooltip"></SfButton>
</SfTooltip>
