C# Delegate eventhandler SelectedIndexChanged

Question

I want to pass another value to the method LeCmb_Statut_SelectedIndexChanged, how can I proceed?

I have the code:

SqlDataReader reader = comm.ExecuteReader(); 
while (reader.Read())
{
   ...
   DropDownList LeCmb_Statut = new DropDownList();
   string tempLabel = reader["LIBELLE"].ToString();
   string templabelVeh = reader["LIBVEH"].ToString()
}

How can I pass these temp variables into LeCmb_Statut_SelectedIndexChanged?

LeCmb_Statut.SelectedIndexChanged += new EventHandler(LeCmb_Statut_SelectedIndexChanged);
