Overview
TOTVS marks MsGetDados deprecated and recommends Protheus MVC for new work. The grid uses Private aRotina, aHeader, aCols and lRefresh. aCols follows header fields plus a logical deletion column. Documented properties include aAlter (editable fields), nMax (row limit) and lDeleta (enable deletion). Syntax below lists the constructor; this page’s method catalog is a maintenance subset, not the entire API. (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 Ed541()
// 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.
