Answer 1

Try passing DataSet instead of DataTable like this

Session["GridData"] = ds.Tables[0];

All the other code can stay as it is.

Hello you can use like this In bussearch.aspx.cs

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (Session["GridData"] != null)
            {
                DataTable dt = new DataTable();
                dt = Session["GridData"] as DataTable;
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }
        }
    }
