Data Transfer using Session Variables

Storing and retrieving Data to and from
session variables on the page we want
To store a value in session we need to write
protected void btnGo_Click(object sender, EventArgs e)
{
Session["VariableName"] = txtData.Text;
Response.Redirect("Deault2.aspx");
}
To retrieve value from Session on other page
string strData = Session["VariableName"].ToString();
Don't forget to use proper typecasting as session stores data as Object and we need
to change it to desired type
To remove Session Variables use
Session.Contents.Remove("VariableName"); or
Session.Contents.RemoveAll(); or
Session.Abandon();
