Hi Panayan Sessions can be used to store even complex data for the user just like cookies. Actually sessions will use cookies to store the data unless you explicitly tell it not to. Sessions can be used easily in ASP.NET with the Session object. We will re-use the cookie example and use sessions instead. Keep in mind though that sessions will expire after a certain amount of minutes as configured in the web.config file. Markup code: Sessions Select color... Red Green Blue And here is the CodeBehind: using System; using System.Data; using System.Web; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender EventArgs e) { if(Session[BackgroundColor] != null) { ColorSelector.SelectedValue = Session[BackgroundColor].ToString(); BodyTag.Style[background-color] = ColorSelector.SelectedValue; } } protected void ColorSelector_IndexChanged(object sender EventArgs e) { BodyTag.Style[background-color] = ColorSelector.SelectedValue; Session[BackgroundColor] = ColorSelector.SelectedValue; } } Session Management can be achieved in two ways 1)InProc 2)OutProc An inproc is one which runs in the same process area as that of the client giving the advantage of speed but the disadvantage of stability because if it crashes it takes the client application also with it. Outproc is one which works outside the client's memory thus giving stability to the client but we have to compromise a bit on speed. Thanks
