Tooltip template

You can use the TooltipTemplate tag directive to specify a custom template for the Tooltip of the rating. The current value of the rating will be passed as the context when building the content of the tooltip. This allows you to include dynamic information about the rating in the template.

@using Syncfusion.Blazor.Inputs

<SfRating Value=4 ShowTooltip=true>
        <b>@((context == 1)?"Angry":(context == 2)?"Sad":(context == 3)?"Neutral":(context == 4)?"Good":"Happy")</b>
