Overview
Legacy class editing rows in the temporary alias supplied as constructor cTRB. Requires Private aRotina and aHeader; table layout must follow the header and contain the final logical deletion flag. Enable and Disable control interaction; ForceRefresh updates and positions at the first row. Validation callbacks must be accessible functions, not Static. This fragment covers only those three methods and creates neither table nor dialog. (Sources: refs. 1–1.)

Return value
Class instance.
EnableEnables interaction.oGrid:Enable()
DisableDisables interaction.oGrid:Disable()
ForceRefreshRefreshes its data source and moves to the first row.oGrid:ForceRefresh()
Return value
New returns the object; this example does not use the other methods’ returns.
Commented example
#Include "Protheus.ch"
User Function Ed542()
// Requires an object already built in the correct dialog; block not invoked.
Local bRefresh := {|oGrid| oGrid:ForceRefresh()}
ConOut(ValType(bRefresh))
Return NilExpected result
Prints B. When invoked with a valid object, refresh may change the current row. Under review: editorial example neither compiled nor run in Protheus. Check includes, release, RDD and context before testing.
- Check the signature and all optional arguments in the source before construction. Restore work areas and release resources on errors. Refresh does not save data; preserve user selection and validate rows before persistence.
