Jquery Method to get querystring values

Jquery Method to get querystring values

Reference link :http://stackoverflow.com/questions/901115/get-query-string-values-in-javascript
I like the way of stack overflow user as they help the users :

function getParameterByName(name)
{
  name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
  var regexS = "[\\?&]" + name + "=([^&#]*)";
  var regex = new RegExp(regexS);
  var results = regex.exec(window.location.search);
  if(results == null)
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}

page load event with working example in c#

I have google a lot for working example of page events in C# but i was not able to find code in c# but found in vb. then i decided to write my own example in c# , so that it may help all my .net friends.
Here are two pages code one is .aspx and other one is .aspx.cs :

Default.aspx : 
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
 <asp:PlaceHolder runat="server" ID="LabelPlaceHolder" >
     <%--<asp:Label ID="lblMessage" runat="server" Text="Label"></asp:Label>--%>
 </asp:PlaceHolder>
    <br />
    <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None">

-----------------------------------------------------------------------------------------
I have used this code in vs2010.

Try using breakpoin with every event . and then debug .
By using Debugger . you can check which event fires first and what can we do with each event..

HOPE THIS HELPS  :)

Thanks
