Appearance Settings

You can control the appearance of the Switch button by setting the following attribute:

• Size
• ThumbRounded
• TrackRounded

Size

You can increase or decrease the size of the Switch by setting the Size attribute to a member of the Telerik.Blazor.ThemeConstants.Switch.Size class:

Class members	Manual declarations
Small	sm
Medium	md
Large	lg

The built-in sizes

@{
    var fields = typeof(Telerik.Blazor.ThemeConstants.Switch.Size)
        .GetFields(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static
        | System.Reflection.BindingFlags.FlattenHierarchy)
        .Where(field => field.IsLiteral && !field.IsInitOnly).ToList();


    @foreach (var field in fields)
    {
        string size = field.GetValue(null).ToString();

        <div style="float:left; margin: 20px;">
            <TelerikSwitch @bind-Value="@isSelected" Size="@size"></TelerikSwitch>
        </div>
    }
}

@code{
    private bool isSelected { get; set; }
}

ThumbRounded

The ThumbRounded attribute applies the border-radius CSS rule to the thumb of the switch to achieve curving of the edges. You can set it to a member of the Telerik.Blazor.ThemeConstants.Switch.ThumbRounded class:

Class members	Manual declarations
Small	sm
Medium	md
Large	lg
Full	full

        .Where(field => field.IsLiteral && !field.IsInitOnly).ToList();

    }
}

@code{
    private bool isSelected { get; set; }
}

ThemeBuilder

To take full control over the appearance of the Telerik UI for Blazor components, you can create your own styles by using ThemeBuilder.

ThemeBuilder is a web application that enables you to create new themes and customize existing ones. Every change that you make is visualized almost instantly. Once you are done styling the UI components, you can export a ZIP file with the styles for your theme and use them in your Blazor app.
