Button types

The types of Blazor Button are as follows:

• Flat Button
• Outline Button
• Round Button
• Toggle Button

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.

@using Syncfusion.Blazor.Buttons

<SfButton CssClass="e-flat">Flat</SfButton>
<SfButton CssClass="e-outline">Outline</SfButton>
<SfButton CssClass="e-round" IconCss="e-icons e-plus-icon" IsPrimary="true"></SfButton>

        content: '\e823';
    }

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 OnClick 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 OnClick event.

@using Syncfusion.Blazor.Buttons

<SfButton CssClass="e-flat" IsPrimary="true" IconCss="@IconCss" Content="@Content" IsToggle="true" @onclick="OnToggleClick" @ref="ToggleBtnObj"></SfButton>

@code {
    SfButton ToggleBtnObj;
    public string IconCss = "e-icons e-play";
    public string Content = "Play";
    public void OnToggleClick()
    {
        if(ToggleBtnObj.Content == "Play")
        {
            this.Content = "Pause";
            this.IconCss = "e-icons e-pause";
        }
        else
        {
            this.Content = "Play";
            this.IconCss = "e-icons e-play";
        }
    }
}
