Label Biglbl = new Label();//LabelBig
Biglbl = (Label)GridView1.Rows[i].FindControl("LabelBig");
int _LidBig = int.Parse(Biglbl.Text);
string queryBig = "select CategoryBig_Id, CategoryBig_Name from Category_Big where CategoryBig_Id=" + _LidBig;
string connectionString = ConfigurationManager.ConnectionStrings["SuoMaWDataConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(connectionString);
myConnection.Open();
SqlCommand CmdBig = new SqlCommand(queryBig, myConnection);
SqlDataReader Bigmm = CmdBig.ExecuteReader();
