How to extract QueryString Parameter value from AbsoluteUri in ASP.Net

You have to use QueryString for that

private int MaxEventID
        {
            get
            {
                return (Request.QueryString["maxEventID"] == null ? 0 : int.Parse(Request.QueryString["maxEventID"]));
            }
        }

Now you can use this make use of this value such as to assign to label

lblName.Text = this.MaxEventID.ToString()

Thank You.
