**AbstractDynamicFormPlugIn 全部事件：** 同 AbstractBillPlugIn 事件减去 Bill 专有事件（BeforeSave / BeforeSubmit / AfterSubmit / CopyData / LoadData 等）。核心事件：**OnLoad / AfterBindData / DataChanged / BarItemClick / EntryBarItemClick / ButtonClick / EntryButtonCellClick / BeforeF7Select / BeforeDoOperation / AfterDoOperation / BeforeClosed / EntityRowClick / EntityRowDoubleClick / AfterDeleteRow / BeforeDeleteRow / AfterCreateModelData / AfterCreateNewEntryRow**（完整列表见 FormPlugin.md 的 AbstractDynamicFormPlugIn 继承节）
