Persist Server side Object Between PostBacks on ASP.NET

This is handy if you want a collection to persist between postback, good for general prototyping or testing.

Set the Item to static as shown below.

        private static MyData  DAL { get; set; }

        

        protected void Page_Load(object sender, EventArgs e)

        {

            if (IsPostBack)

                return;

            DAL = new MyData();

            grid1.DataSource = DAL.Customers;

            grid1.DataBind();

        }
