Answer 1

Am not sure for you scenario. But here is the thing for adding grid view dynamically without using database.

 protected void Page_Load(object sender, EventArgs e)
{
    if (IsPostBack == false)
    {
        DataTable date = new DataTable();
        date.Columns.Add("Column !", typeof(string));
        date.Columns.Add("Column 2", typeof(string));
        Session["dte"] = date;
     }
 }

protected void addbutton_Click(object sender, ImageClickEventArgs e)
{
    DataTable date = (DataTable)Session["dte"];
    DataRow dr = date.NewRow();
    dr["Column 1"] = TextBox1.Text.Trim();// Your Values
    dr["Column 2"] = TextBox2.Text.Trim();// Your Values
    date.Rows.Add(dr);
    GridView1.DataSource = date;
    GridView1.DataBind();
}

It may help you to over come this hurdle. Please let me know your further queries in this case.

You need to get the previous datatable from session and read it and put rows in it. This should be done at addrow AddButton_Click event.
