get RadioButtonList selected value.

You can use jQuery / JavaScript to get the selected value of a RadioButtonList . jQuery provides much more simpler approach as shown below.

jQuery
var selectedVal = $('#<%= RadioButtonList.ClientID %> input:checked').val();

JavaScript

var radioList= document.getElementById("<%= RadioButtonList.ClientID %>");
var options= radioList.getElementsByTagName("input");
var selected;
for (var i = 0; i < options.length; i++) {
if (options[i].checked) {
selected = options[i];
break;
}
}
if (selected) {
alert(selected.value);
}

retrieve RadioButtonList selected value from jQuery

You can use jQery to get RadioButtonList selected value as shown below.

var selectedVal = $('#<%= RadioButtonList.ClientID %> input:checked').val();

If you inspect the HTML DOM for a radiobutton list, you can observe that it is a set of <input type="radio"> with the same name attribute. So you can use getElementsByName to access the collection of radio buttons their index as shown below.

alert(document.getElementsByName('RadioButtonListName') [0].checked);

Adding Web Optimization framework to ASP.Net Web forms

The ASP.Net Web Optimization Framework is used to optimize the ASP.NET web application performance by reducing the number of server requests and the size of the requested resources.

Following article explains how to integrate the ASP.Net Web Optimization Framework to to ASP.Net Web forms project.

When the scripts are rendered in the master page a place holder is used to wrap the rendered scripts as shown below.

<asp:PlaceHolder runat="server">

<%: Scripts.Render("~/bundles/jquery") %>

<%: Styles.Render("~/Content/bootstrap") %>

</asp:PlaceHolder>

</head>

This ensures that bundles are rendered properly.

check connenction from javascript

We can use javascript to check the current connection and determine if we run in local host. Here I have included the checking of custom domain name as well,

if (window.location.hostname === "localhost" || location.hostname === "127.0.0.1" || window.location.hostname.indexOf('.local') >= 0) {
alert("Running Locally");
}

Cheers,
