Multiple CheckBoxList

 Hello to Everyone,

The problem i have is that i can  add various CheckBoxList Controls to a placeholder but i can't after the page previewed retrieve the controls.

 

With this i add the Controls to a placeholder :

foreach (TermData name in SupplierParrent) {
                        CheckBoxList checkBoxList = new CheckBoxList();
                        IList<TermData> SupplierChild = new List<TermData>();
                        SupplierChild = tdDao.listSchools(vocabulary, name.TermId);
           &n ...
