Session End on Browser Close or Tab Close or Moving out of the site


I have seen lots of post in the forum asking about kill session on close of browser or tab or moving out of the site.

We can kill session on any of the following case mentioned above using Ajax Callback with Javascript.
Here are the steps to follow:

Step 1: Add ScriptManager in the aspx page
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
Step 2: Add onuload in body tag which will call BrowserClose method in Javascript.
<body onunload="BrowserClose()">
Step 3: Now add javascript method of BrowserClose which will call KillSession method of code behind
<script language="javascript" type="text/javascript">
function BrowserClose()
{
   PageMethods.KillSession();
}
<script>
Step 4: In code behind file, KillSession method will contain the Session.Abandon which will abandon the session.
KillSession method has to be signatured with WebMethod.
Make the KillSession method static
[System.Web.Services.WebMethod()]
public static void KillSession()
{
   HttpContext.Current.Session.Abandon();
}
Step 5 : The code which needs to be executed on should be placed in Session_End method of Global.asax.cs
protected void Session_End(object sender, EventArgs e)
{
   //Code to execute on Session End
}

GRIDVIEW GROUPING

When displaying data, we sometimes would like to group data for better user experience or when displaying long list of hierarchal data, we would want to display them in a tree view kind of structure. There is more than way of doing this, but I am going to explain achieving this functionality using  AJAX Collapsible Panel Extender Control . Overview: I am going to use  Adventure Works  as datasource. Every product in  Production.Product  table belongs to a product sub category. We fetch handful of products and the sub categories they belong to from the database. Our objective is to list all the available sub categories and allow user to  expand/collapse  to look/hide the list of products belonging to each subcategory. Database Connection Added following entry under  connectionStrings  element in  web.config . < add   name = "Sql"   connectionString="Data Source=(local); Initial  Catalog = AdventureWorks ...

ADO.NET Concepts With example

COMMAND OBJECT  Command object is the biggest object in ADO.NET  It is the only object which can perform actions with database  It  can be created directly using Command class or can be created using Connection.Create command (factory classes also contain creation of Command). Ex:  SqlConnection sqlCon = new SqlConnection("......");    SqlCommand sqlCmd = sqlCon.CreateCommand();  Commands that we run depend upon the kind of query that we want to execute with database. All databases support two types of queries. i. Action Queries ii. Non-action Queries Action queries are those which change the state of database and which don‟t return any query results(though they return the number of records affected). Ex: Insert, Delete and Update statements Non-action queries are those which don‟t affect the database but return the results to the user. Ex: Select statement Method of execution of queries: Command object provides the following methods to execute queries: 1. Ex...
