How to Create Rating Control in ASP.Net With Bootstrap

Introduction
 
This article will help you to create a rating control in ASP.Net with Bootstrap instead of AJAX rating control.
 
Step 1

Download the CSS and JavaScript files from github.com.

Step 2
 
Open your Visual Studio, then add your downloaded file into your project then add index.aspx page and call your necessary files within the head tag from that downloaded folder.
  1. <head runat="server">  
  2.     <title></title>  
  3.     <link href="Bootstrap/css/bootstrap.min.css" rel="stylesheet" />  
  4.     <link href="Bootstrap/css/star-rating.css" rel="stylesheet" />  
  5.     <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  
  6.     <script src="Bootstrap/js/star-rating.js"></script>  
  7. </head>  
Step 3
 
Now call your rating control. Before calling your rating control please learn how to use Bootstrap from my previous article.
  1. <div class="row">  
  2.   <div class="col-lg-12">  
  3.    
  4.   <input id="input-21a" value="0" type="number" class="rating" data-symbol="*" min=0 max=5 step=0.5 data-size="xl" >  
  5.   <hr>  
  6.   <input id="input-21b" type="number" class="rating" min=0 max=5 step=0.5 data-glyphicon="false" data-star-captions="{}" data-default-caption="{rating} Stars" data-size="lg">  
  7.   <hr>  
  8.   <input id="input-21c" value="0" type="number" class="rating" min=0 max=8 step=0.5 data-size="xl" data-stars="8">  
  9.   <hr>  
  10.   <input id="input-21d" value="2" type="number" class="rating" min=0 max=5 step=0.5 data-size="sm">  
  11.   <hr>  
  12.   <input id="input-21e" value="0" type="number" class="rating" min=0 max=5 step=0.5 data-size="xs" >  
  13.   <hr>  
  14.   </div>  
  15. </div>  
Here, value is your filled start on page load, min is the minimum star value, max is the maximum star or maximum rating, data-size is your rating control size.

Step 4
 
Now we can see how to get the rated value from this rating control using jQuery as in the following:
  1. <script>  
  2.        $(document).ready(function () {  
  3.            $("#input-21b").on("rating.change", function (event, value, caption) {  
  4.                alert("You rated: " + value + " = " + $(caption).text());  
  5.            });  
  6.        });  
  7.    </script>  
Step 5
 
Let's see how to get the rated value from code behind in C#. Add one hidden field in your design page and assign your rated value into your hidden field.
  1. <asp:HiddenField ID="hdfRatingValue" runat="server" />  
Now assign your rated value into your hidden field. Let's see how to do this using jQuery. 
  1. <script>  
  2.        $(document).ready(function () {  
  3.            $("#input-21b").on("rating.change", function (event, value, caption) {  
  4.                  
  5.                var ratingValue = $('#<%=hdfRatingValue.ClientID%>').val();  
  6.                ratingValue = value;  
  7.                alert(ratingValue);  
  8.            });  
  9.        });  
  10.    </script>  
Now you can get the rating value from code behind. Type hdfRating.value and save your value to the database.
