Ratings provide insight regarding other's opinions and experiences with a product.

Collecting user feedback via ratings is a simple analytic that can provide a lot of feedback to your product or application.

Basic Rating

<MudRating SelectedValue="2" />

A disabled component cannot change its state. Use the Disabled parameter to disable a component.

<MudRating Disabled="true" SelectedValue="2" />
Read only

A read-only component doesn't allow interactions. Use the ReadOnly parameter to mark a component as read-only.

<MudRating ReadOnly="true" SelectedValue="2" />

<div class="d-flex flex-column align-center">
    <MudRating SelectedValue="2" Size="Size.Small" />
    <MudRating SelectedValue="2" Size="Size.Medium" />
    <MudRating SelectedValue="2" Size="Size.Large" />
Max value

<div class="d-flex flex-column align-center">
    <MudRating SelectedValue="1" MaxValue="3" />
    <MudRating SelectedValue="2" />
    <MudRating SelectedValue="3" MaxValue="10" />
Icons and color

Icons and colors can be set separately for Empty and Full icons. Icons can be set using FullIcon and EmptyIcon properties, while Color can be set using Color attribute for both icons, or separately for full/empty icons using FullIconColor and EmptyIconColor properties. If one of those is not set, the component will use the value set in Color property for both empty and full.

<div class="d-flex flex-column align-center">
    <MudRating SelectedValue="2" FullIcon="@Icons.Material.Filled.Visibility" EmptyIcon="@Icons.Material.Filled.VisibilityOff" />
    <MudRating SelectedValue="2" FullIcon="@Icons.Material.Filled.Favorite" EmptyIcon="@Icons.Material.Filled.FavoriteBorder" Color="Color.Secondary" />
    <MudRating SelectedValue="2" FullIcon="@Icons.Material.Filled.Square" EmptyIcon="@Icons.Material.Filled.Square" FullIconColor="Color.Primary" EmptyIconColor="Color.Tertiary" />
Events and value binding

The MudRating component provides value binding and events for changed selected value or hover. E.g you can display a label on hover to help users pick the correct rating value, using parameters like HoveredValueChanged, SelectedValueChanged and bind-SelectedValue.
