    NOTE

    Add necessary images to the mentioned directory. <project directory>/Images/rating/yourimage.png

    Set Min and Max Value  

    In a real-time movie Rating scenario, you can extend the range by using the properties MinValue and MaxValue. Only rates ranging between the MinValue and MaxValue appear in the Rating.

    Add the following code example to the corresponding ASPX page to set MinValue and MaxValue to the Rating.

  • html
  • <div class="frame">
    
        <table>
    
            <tr>
    
                <td valign="top">
    
                    Rate:

            </tr>
    
        </table>
    
    </div>

    Execute the above code to render the following output.

    Set Precision

    In a real-time movie Rating scenario, you can rate the Rating between two whole numbers, such as 2.5 or 3.7 by using the Precision property. You can also add additional functionalities such as Orientation and APIs to the Rating.

    Add the following code example to the corresponding view page to set Precision to Rating.
