Ext's own SetValue function does not trigger the change, as well as the Blur event, the linkage of the multiple controls is a nightmare, such as the age of the birth of the linkage, when the birth date changes, in the Change event to call the age of the control of the SetValue changes in the age of the value, After the age change, automatically inquires some things and so on; because the SetValue function does not trigger the Change event, age changes do not query; This can be invoked to trigger a setvaluewithevent event; (This estimate that we use less, after all, not so many linkage)
