Session

Here, we will see how to Storing and Retrieving values from Session. A session is defined as the period of time that a unique user interacts with a Web application. HTTP is a stateless protocol, it can't hold the client information on page. If user inserts some information, and move to the next page, that data will be lost and user would not able to retrieve the information. So what we need? we need to store information. Session provides that facility to store information on server memory.

Now creating a web application with two form. one for storing value of session and other for retrieving session value.

Storing a value to session

Now drag and drop a TextBox and a button control on the form.

.ASPX code

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

        <br />

        <br />

 <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

Now double click on the Button control and add the following code.

.cs code

Public Class sessionstore

    Inherits System.Web.UI.Page

 

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Session("UserName") = TextBox1.Text

 

    End Sub

 

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click

        Response.Redirect("sessionretrive.aspx")

    End Sub

End Class

 

Retrieve session value

Now Taking another form to retrieve session value. Drag a label control on the form and add the following code on the page load event.

Public Class sessionretrive

    Inherits System.Web.UI.Page

 

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Session("UserName") IsNot Nothing Then

 

            Label1.Text = "Welcome : " + Session("UserName")

        Else

        End If

    End Sub

End Class

Now run the application and test it.
