Getting Started with the Button

This tutorial explains how to set up a basic Telerik UI for ASP.NET MVC Button and highlights the major steps in the configuration of the component.

You will initialize two buttons, one of them will have an event handler, an icon, and a badge. The other one will be rendered as disabled.

Sample Telerik UI for ASP.NET MVC Button

Prerequisites

To successfully complete the tutorial, you need a project that is already configured to use the Telerik UI for ASP.NET MVC components:

1. Prepare the CSHTML File

The first step is to add the required directives at the top of the .cshtml document:

  • To use the Telerik UI for ASP.NET MVC HtmlHelpers: @using Kendo.Mvc.UI

Optionally, you can structure the document by adding the desired HTML elements like headings, divs, paragraphs, and others.

    @using Kendo.Mvc.UI

    <h4>Button with event handler</h4>
    <p>

    </p>
    <p id="date"></p>

    <h4>Disabled Button</h4>
    <p>

    </p>

2. Initialize the Button

Use the Button HtmlHelper to add the component to a page:

  • The Name() configuration method is mandatory as its value is used for the id and the name attributes of the Button element.
  • The Content() configuration specifies the text that is rendered within the button. This option accepts only string values and no HTML.
  • The Enable() configuration defines if the component is enabled or disabled.
    @using Kendo.Mvc.UI

    <h4>Button with event handler</h4>
    <p>
        @(Html.Kendo().Button()
            .Name("dateButton")
            .Content("What date is it?"))
    </p>
    <p id="date"></p>

    <h4>Disabled Button</h4>
    <p>
        @(Html.Kendo().Button()
            .Name("disabledButton")
            .Content("Disabled button")
            .Enable(false))
    </p>

3. Add an Icon and a Badge

The next step is to display an icon and a badge within the Button. This allows you to enhance its visual representation.

    @using Kendo.Mvc.UI

    <h4>Button with event handler</h4>
    <p>
        @(Html.Kendo().Button()
            .Name("dateButton")
            .Content("What date is it?")
            .Icon("calendar")
            .Badge(b => b
                .Text("new")
                .Shape(BadgeShape.Pill)
                .Size(BadgeSize.Medium)
                .ThemeColor(BadgeColor.Info)))
    </p>
    <p id="date"></p>

    <h4>Disabled Button</h4>
    <p>
        @(Html.Kendo().Button()
            .Name("disabledButton")
            .Content("Disabled button")
            .Enable(false))
    </p>

4. Handle a Button Event

The Button exposes a Click() event that you can handle and assign specific functions to the component. In this tutorial, you will use the Click() event to display the current date and time.

    @using Kendo.Mvc.UI

    <h4>Button with event handler</h4>
    <p>
        @(Html.Kendo().Button()
            .Name("dateButton")
            .Content("What date is it?")
            .Icon("calendar")
            .Badge(b => b
                .Text("new")
                .Shape(BadgeShape.Pill)
                .Size(BadgeSize.Medium)
                .ThemeColor(BadgeColor.Info))
            .Events(ev => ev.Click("onClick")))
    </p>
    <p id="date"></p>

    <h4>Disabled Button</h4>
    <p>
        @(Html.Kendo().Button()
            .Name("disabledButton")
            .Content("Disabled button")
            .Enable(false))
    </p>

    <script>
    function onClick(e) {
    document.getElementById('date').innerHTML=Date(); 
    }
    </script>

For more examples, refer to the demo on using the events of the Button.

5. (Optional) Reference Existing Button Instances

You can reference the Button instances that you have created and build on top of their existing configuration:

  1. Use the id attribute of the component instance to establish a reference.

    <script>
        var buttonReference = $("#dateButton").data("kendoButton"); // buttonReference is a reference to the existing dateButton instance of the helper.
    </script>
    
  2. Use the Button client-side API to control the behavior of the widget. In this example, you will use the enable method to disable the button.

    <script>
        var buttonReference = $("#dateButton").data("kendoButton"); // buttonReference is a reference to the existing dateButton instance of the helper.
        buttonReference.enable(false); // Disable the button.
    </script>
    

For more information on referencing specific helper instances, see the Methods and Events article.
