Hello friends, What i am trying here is to pass values to other pages. When i include the following code

private void Button1_Click(object sender, System.EventArgs e)
{
    // Value sent using HttpResponse

    Response.Redirect("WebForm5.aspx?Name="+txtName.Text);
}

if (Request.QueryString["Name"]!= null)

Response.write( Request.QueryString["Name"]);

everything works fine the name gets displayed. Now if use MemberId instead, though i can see the Id in the Url, but while checking for Null in other page, its true. Whats wrong??

Now I tried the same thing using session i.e.

Session["MemberId"] = this.TxtEnterMemberId.Text;

 if (MemberSex.Equals("M"))
                        Response.Redirect("PatientDetailsMale.aspx",false );



Page_load event of the other page
        if (Session["MemberId"] != null)
           mid = Session["MemberId"].ToString();

IT Works..Could u guys explain the behaviour please?

P.S. Can anyone give a breif in layman words about SessionId and its usage.

Thanking you,

Indranil
