私の場合、DropDownList Items ディクショナリの複数の項目で選択が true だったためです。

 if (DropDown.Items.FindByText(value) != null) {
      //important note:  
      //below line will reset selected true if previously this field is set and  caused the exception and must be removed
      //DropDown.SelectedIndex = -1;
      DropDown.Items.FindByText(value).Selected = true;
   }
