if (CheckBoxList1.Items[i].Selected == true)            {                
if (checkid != string.Empty)                    
checkid += "," + CheckBoxList1.Items[i].Value;                else

                foreach (string strinfo in str)
                {
                    ListItem NewItem = (ListItem)CheckBoxList1.Items.FindByValue(strinfo);
                    if (NewItem != null)
                        NewItem.Selected = true;
                }
            }
