12 Jan 20234 minutes to read

You can also customize the appearance of rating component.

Items count

You can specify the number of rating items using the ItemsCount property.

@using Syncfusion.Blazor.Inputs

<SfRating Value="3" ItemsCount="8"></SfRating>

In this example, the rating component will display 8 rating items. The Value property specifies the number of rating items that should be filled, so in this case 3 of the 8 rating items will be filled.

Disabled

You can disable the Syncfusion Blazor Rating component by using the Disabled property. When the Disabled property is set to true, the rating component will be disabled and the user will not be able to interact with it and a disabled rating component may have a different visual appearance than an enabled one.

@using Syncfusion.Blazor.Inputs

<SfRating Value="3" Disabled=true></SfRating>

Visible

You can use the Visible property of the Blazor Rating component to control the visibility of the component. When the Visible property is set to true, the rating component will be visible on the page. When it is set to false, the component will be hidden.

@using Syncfusion.Blazor.Inputs

<SfRating Value="3" Visible=true></SfRating>

Read only

You can use the ReadOnly property of the Blazor Rating component to make the component non-interactive and prevent the user from changing the rating value.

@using Syncfusion.Blazor.Inputs

<SfRating Value="3" ReadOnly=true></SfRating>

CssClass

You can customize the appearance of the rating component, such as by changing its colors, fonts, sizes, or other visual aspects by using the CssClass property.

Changing rating symbol border color

    .e-rating-container.custom-font .e-rating-item-container .e-rating-icon {
        /* To change rating symbol border color */
        -webkit-text-stroke: 2px #ae9e9d;        
    }

</style>

Changing rated/un-rated symbol fill color

You can customize the fill colors of rated and un-rated icons in the Rating component using the CssClass property and the linear-gradient color-stops in the background CSS property of .e-rating-icon. The first color-stop defines the rated fill color and the second defines the un-rated fill color.

<SfRating Value="3" CssClass="custom-font"></SfRating>

<style>

    .e-rating-container.custom-font .e-rating-item-list:hover .e-rating-item-container .e-rating-icon,
    .e-rating-container.custom-font .e-rating-item-container .e-rating-icon {
        /* To change rated symbol fill color and un-rated symbol fill color */
        background: linear-gradient(to right, #ffe814 var(--rating-value), #d8d7d4 var(--rating-value));
        background-clip: text;
        -webkit-background-clip: text;
    }
