Hi Vineet, Normal 0 Application State : - We can declare variables, objects in the application state. If we assign any value in the application state it can be globally accessed in any WebPages of the current application. Program First add a Global Application Class to the current application. Global.asax code @ import Namespace ="System.Data" %> @ import Namespace ="System.Data.SqlClient" %> @ Application Language ="VB" %> script runat ="server"> Dim strConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings.Item( "ConnectionString" ).ToString() Dim con As New SqlConnection(strConnString) Dim str As String Dim com As SqlCommand Dim ds As DataSet Dim da As SqlDataAdapter Sub Application_Start( ByVal sender As Object , ByVal e As EventArgs) ' Code that runs on application startup Application( "sqlconstring" ) = str Application( "sqlcon" ) = con Application( "sqlcom" ) = com Application( "sqldataset" ) = ds Application( "sqldataadapter" ) = da End Sub Sub Application_End( ByVal sender As Object , ByVal e As EventArgs) ' Code that runs on application shutdown End Sub Sub Application_Error( ByVal sender As Object , ByVal e As EventArgs) ' Code that runs when an unhandled error occurs End Sub Sub Session_Start( ByVal sender As Object , ByVal e As EventArgs) ' Code that runs when a new session is started End Sub Sub Session_End( ByVal sender As Object , ByVal e As EventArgs) ' Code that runs when a session ends. ' Note: The Session_End event is raised only when the sessionstate mode ' is set to InProc in the Web.config file. If session mode is set to StateServer ' or SQLServer, the event is not raised. End Sub script > Default.aspx code @ Page Language ="VB" AutoEventWireup ="false" CodeFile ="Default.aspx.vb" Inherits ="_Default" %> DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> html xmlns ="http://www.w3.org/1999/xhtml"> head runat ="server"> title > Untitled Page title > head > body > form id ="form1" runat ="server"> div > asp : GridView ID ="GridView1" BackColor ="#FF9999" runat ="server"> HeaderStyle BackColor ="#FFCC99" /> asp : GridView > br /> asp : Button ID ="Button1" runat ="server" Text ="Display Records" /> div > form > body > html > Default.aspx.vb code Imports System.Data Imports System.Data.SqlClient Partial Class _Default Inherits System.Web.UI.Page Protected Sub Button1_Click( ByVal sender As Object , ByVal e As System.EventArgs) Handles Button1.Click Try Application( "sqlcon" ).open() Application( "sqlconstring" ) = "select * from employee" Application( "sqlcom" ) = New SqlCommand(Application( "sqlconstring" ), Application( "sqlcon" )) Application( "sqldataadapter" ) = New SqlDataAdapter(Application( "sqlcom" )) Application( "sqldataset" ) = New DataSet Application( "sqldataadapter" ).fill(Application( "sqldataset" ), "employee" ) GridView1.DataSource = Application( "sqldataset" ) GridView1.DataMember = "employee" GridView1.DataBind() Application( "sqlcon" ).close() Catch ex As Exception Response.Write(ex.Message) End Try End Sub End Class Thanks If this post helps you mark it as answer
