23 Jan 20232 minutes to read

The ASP.NET Core rating control supports tooltip to show additional information in rating items by setting the showTooltip property. If enabled, the tooltip appears when the user hovers over a rating item.

@using Syncfusion.EJ2.Inputs

<ejs-rating id="rating" value=3 showTooltip=true></ejs-rating>

ASP.NET Core Rating Control with Tooltip

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 value property in the template context when building the content of the tooltip. This allows you to include dynamic information about the rating in the template.

@using Syncfusion.EJ2.Inputs

<ejs-rating id="rating" value=4 tooltipTemplate="#template"></ejs-rating>

<script id="template" type="text/x-jsrender">
    ${if(value==1)}
    <b>Angry</b>${else if(value==2)}
    <b>Sad</b>${else if(value==3)}
    <b>Neutral</b>${else if(value==4)}
    <b>Good</b>${else}
    <b>Happy</b>
    ${/if}
</script>
