The types of Essential JS 2 Button are as follows:

Basic types
Flat Button
Outline Button
Round Button
Toggle Button

Basic types

The basic Button types are explained below.

Type	Description

In the following sample, type attribute of the Submit button is set using tag helper and Reset button is set using htmlAttribute.

CSHTML
@{IDictionary<string, object> submit = new Dictionary<string, object>();
    submit.Add("type", "submit");
}
@{IDictionary<string, object> reset = new Dictionary<string, object>();
    reset.Add("type", "reset");
}
<ejs-button id="submit" content="Submit" htmlAttributes="submit"></ejs-button>
<ejs-button id="reset" content="Reset" htmlAttributes="reset"></ejs-button>

<style>
  button {
    margin: 25px 5px 20px 20px;
  }
</style>

Flat Button

The Flat Button is styled with no background color. To create a flat Button, set the cssClass property to e-flat.

Outline Button

An outline Button has a border with transparent background. To create an outline Button, set the cssClass property to e-outline.

Round Button

A round Button is shaped like a circle. Usually, it contains an icon representing its action. To create a round Button, set the cssClass property to e-round.

CSHTML
<ejs-button id="flat" cssClass="e-flat" content="Flat"></ejs-button>
<ejs-button id="outline" cssClass="e-outline" content="Outline"></ejs-button>
<ejs-button id="round" cssClass="e-round" iconCss="e-icons e-plus-icon" isPrimary="true"></ejs-button>

<style>

button {
  margin: 25px 5px 20px 20px;
}

.e-plus-icon::before {
  content: '\e823';
}

</style>

Toggle Button

A toggle Button allows you to change between the two states. The Button is active in toggled state and can be recognized through the e-active class. The functionality of the toggle Button is handled by click event. To create a toggle Button, set the isToggle property to true. In the following code snippet, the toggle Button text changes to play/pause based on the state of the Button with the use of click event.

CSHTML
<ejs-button id="togglebtn" onclick=clickHandler() cssClass="e-flat" iconCss="e-btn-sb-icons e-play-icon" content="Play" isToggle="true"></ejs-button>

Button with font icons

The Button can have an icon to provide the visual representation of the action. To place the icon on a Button, set the iconCss property to e-icons with the required icon CSS. By default, the icon is positioned to the left side of the Button. You can customize the icon’s position by using the iconPosition property.

The Essential JS 2 provides a set of icons that can be loaded by applying e-icons class name to the element. You can also use third party icons on the Button using the iconCss property.

SVG image can be added to the Button using iconCss property.

In the following example, SVG image is added using the iconCss class e-search-icon by setting height and width property.

CSHTML
<ejs-button id="iconbutton" iconCss="e-search-icon"></ejs-button>

<style>

button {
  margin: 25px 5px 20px 20px;
}

.e-btn-icon.e-search-icon {
   background: url('search_icon.svg'); 
   height: 25px; 
   width: 25px; 
}

</style>

Button size

The two types of Button sizes are default and small. To change the size of the default Button to small Button, set the cssClass property to e-small.

CSHTML
<ejs-button id="smallbtn" cssClass="e-small" content="SMALL"></ejs-button>
<ejs-button id="normalbtn" content="NORMAL"></ejs-button>

  margin: 25px 5px 20px 20px;
