Blazorise Switch component

Switch is used for switching between two opposing states.

The <Switch> component provides users the ability to choose between two distinct values. These are very similar to a toggle, or on/off switch, though aesthetically different than a checkbox.

Switches are the preferred way to adjust settings on mobile. The option that the switch controls, as well as the state it’s in, should be made clear from the corresponding inline label.

Examples

Basic

Remember me

<Switch TValue="bool">Remember me</Switch>

Binding

Two-way binding

Remember Me

<Switch TValue="bool" @bind-Checked="@rememberMe">Remember Me</Switch>

@code{
    bool rememberMe;
}

Manual event binding

Remember Me

<Switch TValue="bool" Checked="@rememberMe" CheckedChanged="@OnRememberMeChanged">Remember Me</Switch>

@code{
    bool rememberMe;

    Task OnRememberMeChanged( bool value )
    {
        rememberMe = value;

        return Task.CompletedTask;
    }
}
