Appearance Settings

You can control the appearance of the toggle button by setting the following attributes:

• FillMode
• Rounded
• Size
• ThemeColor

You can use all of them together to achieve the desired appearance. This article will explain their effect one by one.

    var fields = typeof(Telerik.Blazor.ThemeConstants.Button.FillMode)
        .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 fillmode = field.GetValue(null).ToString();

        <div style="float:left; margin: 20px;">
            <TelerikToggleButton FillMode="@fillmode">@fillmode</TelerikToggleButton>
        </div>
    }
}

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

    foreach (var field in fields)

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

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

        <div style="float:left; margin: 20px;">
            <TelerikToggleButton Size="@size">@size</TelerikToggleButton>
        </div>
    }
}

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.
