Please update your question giving more information on your code and where you are getting issue exactly. Currently, it is telling us nothing.

<script type="text/javascript">
function updateDateKey(value) {
var behavior = $find('dp1');
if (behavior) {
behavior.populate(value);
}
}
Sys.Application.add_load(function () { updateDateKey('Alik Levin'); });
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="ScriptManager1" runat="server">
<div>
<asp:DynamicPopulateExtender ID="DynamicPopulateExtender1" runat="server" BehaviorID="dp1" TargetControlID="form1$Label1" ClearContentsDuringUpdate="true"
ServiceMethod="GetHtml">

<input type="radio"
name="rbFormat"
id="r0"
value='alik'
/>click to set 'alik'<br/>
<input type="radio"
name="rbFormat"
id="Radio1"
/>click to set 'levin'<br />
<asp:Label ID="Label1" runat="server" ForeColor="Red" Text="Label">
</div>
</form>

This is my source code once i run this form it is showing error like "An unhandled exception was generated during the execution of the current web request"

You have to debug and check where exactly it is throwing this exception.
