updateState

Procedure passes along update-related messages (to its Navigation–Source, for example.) and adjusts the DataModified property.

Location: data.p

Parameters:

INPUT pcState AS CHARACTER

An indicator of the state of an updatable record. Valid values are:

UpdateBegin — The user has indicated that an update can take place, either by pressing the Update button in a panel or by entering an updatable field in a browser.
Update — An update is in progress in another object (a viewer or browser).
UpdateEnd — A save has completed (the same as UpdateComplete.)
UpdateComplete — Any changes to the RowObject temp-table have been either committed or backed out.
Notes: The SmartDataObject also saves its own copy of the DataModified property, set TRUE when updateState is Update and FALSE when updateState is UpdateComplete, so that it can be queried by other objects (such as other Data–Targets).
