    sales=pd.read_csv ("C:/Users/DELL/Desktop/Info/Topholdings/csv/Master_table.csv")
    sales_article = sales ["Company"] .dropna()
    sales_list = sales_article.values.tolist()
    self.Fundwise = QtWidgets.QComboBox(Dialog)

def setupUi(self, Dialog):
     #....
     self.Fundwise.activated.connect(self._set_fundwise)

def _set_fundwise(self):
    _data = self.Fundwise.currentData()
    if _data:
       #call selected strings
