in page_load if you write down

protected void Page_Load(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    String strConnString = "Data Source=\\SqlExpress;Initial Catalog=HRDB;User ID=sa;";
    SqlConnection con = new SqlConnection(strConnString);
    SqlDataAdapter sda = new SqlDataAdapter();
    SqlCommand cmd = new SqlCommand("tblemployee");
    cmd.CommandType = CommandType.Text;
    cmd.CommandText = sqlquery;

    cmd.Connection = con;
    sda.SelectCommand = cmd;
    sda.Fill(dt);       
    gvProducts.DataSource = dt;
    gvProducts.DataBind();
