12 May 20227 minutes to read

This section briefly explains about how to include ASP.NET MVC Tooltip control in your ASP.NET MVC application using Visual Studio.

Prerequisites

System requirements for ASP.NET MVC controls

Create ASP.NET MVC application with HTML helper

Install ASP.NET MVC package in the application

Syncfusion ASP.NET MVC controls are available in nuget.org. Refer to NuGet packages topic to learn more about installing NuGet packages in various OS environments. To add ASP.NET MVC controls in the application, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.EJ2.MVC5 and then install it.

The Syncfusion.EJ2.MVC5 NuGet package has dependencies, Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating Syncfusion license key.

If you create ASP.NET MVC application with MVC4 package, search for Syncfusion.EJ2.MVC4 and then install it.

Add namespace

Add Syncfusion.EJ2 namespace reference in Web.config under Views folder.

<namespaces>
    <add namespace="Syncfusion.EJ2"/>
</namespaces>

Add style sheet

Checkout the Themes topic to learn different ways (CDN, NPM package, and CRG) to refer styles in ASP.NET MVC application, and to have the expected appearance for Syncfusion ASP.NET MVC controls. Here, the theme is referred using CDN inside the <head> of ~/Views/Shared/_Layout.cshtml file as follows,

<head>
    ...
    <!-- Syncfusion ASP.NET MVC controls styles -->
    <link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/20.1.55/fluent.css" />
</head>

Add script reference

In this getting started walk-through, the required scripts are referred using CDN inside the <head> of ~/Views/Shared/_Layout.cshtml file as follows,

<head>
    ...
    <!-- Syncfusion ASP.NET MVC controls scripts -->
    <script src="https://cdn.syncfusion.com/ej2/20.1.55/dist/ej2.min.js"></script>
</head>

Register Syncfusion Script Manager

Open ~/Views/Shared/_Layout.cshtml page and register the script manager EJS().ScriptManager() at the end of <body> in the ASP.NET MVC application as follows.

<body>
...
    <!-- Syncfusion ASP.NET MVC Script Manager -->
    @Html.EJS().ScriptManager()
</body>

Add ASP.NET MVC Tooltip control

Now, add the Syncfusion ASP.NET MVC Tooltip control in ~/Views/Home/Index.cshtml page.

@Html.EJS().Tooltip("Tooltip").Content("Lets go green & Save Earth !!!").ContentTemplate(@<span id='target'>Show Tooltip</span>).Render()

Press Ctrl+F5 (Windows) or +F5 (macOS) to run the app. Then, the Syncfusion ASP.NET MVC Tooltip control will be rendered in the default web browser.

ASP.NET MVC Tooltip Control

Initialize Tooltip within a container

You can create Tooltips on multiple targets within a container. To do so, you have to define specific target elements to the Target property so that the Tooltip is initialized only on matched targets within a container. In this case, the Tooltip content is assigned from the title attribute of the target element.

Refer to the following code example to create a Tooltip on multiple targets within a container.

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Popups
@Html.EJS().Tooltip("Tooltip").Target(".e-info").Position(Syncfusion.EJ2.Popups.Position.RightCenter).ContentTemplate(@<form id="details" role="form">
                        <table>
                            <tr>
                                <td class="info"> User Name:</td>
                                <td> <input type="text" class="e-info" name="firstname" title="Please enter your name"> </td>
                            </tr>
                            <tr>
                                <td class="info"> Email Address:</td>
                                <td> <input type="text" class="e-info" name="email" title="Enter a valid email address"></td>
                            </tr>
                            <tr>
                                <td class="info"> Password:</td>
                                <td> <input type="password" class="e-info" name="password" title="Be at least 8 characters length"></td>
                            </tr>
                            <tr>
                                <td class="info"> Confirm Password:</td>
                                <td> <input type="password" class="e-info" name="Cpwd" title="Re-enter your password"></td>
                            </tr>
                        </table>
                        <input id="sample" type="submit" value="Submit">
                        <input id="clear" type="reset" value="Reset">
                        </form>).Render()

<style>
    #container {
        visibility: hidden;
    }

    #loader {
        color: #008cff;
        height: 40px;
        left: 45%;
        position: absolute;
        top: 45%;
        width: 30%;
    }

    #details table th, #details table td {
        padding: 15px;
        text-align: left;
    }

    #details .info {
        font-weight: bold;
    }
 
</style>

Accessibility in ASP.NET MVC Tooltip

In the above sample, #details refers to the container’s id, and the target .e-info refers to the target elements available within that container.
