Appearance Settings

The loader component provides the following parameters that control its appearance:

• Type
• Size
• ThemeColor

You can use all three together to get the desired appearance. This article will explain their effect one by one.

Type

The Type parameter controls the general shape of the animation. It takes a member of the Telerik.Blazor.Components.LoaderType enum:

• Pulsing
• InfiniteSpinner
• ConvergingSpinner

You can see them in action in the Loader Overview Live Demo.

Loader Types

@foreach (LoaderType type in Enum.GetValues(typeof(Telerik.Blazor.Components.LoaderType)))
{
    <div style="float: left; margin: 20px;">
        @type
        <br /><br />
        <TelerikLoader Type="@type"></TelerikLoader>
    </div>
}

Size

There are three predefined sizes for the loader that you can set through its Size parameter that takes a member of the Telerik.Blazor.Components.LoaderSize enum:

• Small
• Medium - the default value
• Large

You can see them in action in the Loader Overview Live Demo.

Loader Size

@foreach (LoaderSize size in Enum.GetValues(typeof(Telerik.Blazor.Components.LoaderSize)))
{
    <div style="float: left; margin: 20px;">
        @size
        <br /><br />
        <TelerikLoader Size="@size"></TelerikLoader>
    </div>
}

ThemeColor

The color of the animated loading icon is controlled through the ThemeColor parameter. You can set it to a member of the Telerik.Blazor.ThemeColor class:

• Primary
• Secondary
• Tertiary
• Success
• Info
• Warning
• Error
• Dark
• Light
• Inverse

These predefined options match the main Telerik Theme and you can see that in action in the Appearance Live Demo.

Built-in Theme Colors

@{
    var fields = typeof(Telerik.Blazor.ThemeColors)
                    .GetFields(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static |
                       System.Reflection.BindingFlags.FlattenHierarchy)
                    .Where(fi => fi.IsLiteral && !fi.IsInitOnly).ToList();
    foreach (var f in fields)
    {
        string color = f.GetValue(null).ToString();
        <div style="float: left; margin: 20px;">
            @color
            <br /><br />
            <TelerikLoader ThemeColor="@color"></TelerikLoader>
        </div>
    }
}

The ThemeColor parameter renders as the k-loader-<ThemeColor> CSS class on the wrapping element and you can set it to a custom value to cascade through and set the color to a setting of your own without customizing the entire theme.

Custom loader color without customizing the Telerik Theme

<style>
    .k-loader-custom-color .k-loader-segment::after {
        background-color: cyan;
    }
</style>
<TelerikLoader ThemeColor="custom-color"></TelerikLoader>
