Description

TNavigateBtn defines values identifying different possible buttons on a TDBNavigator object.

Each TNavigateBtn value identifies a different button that can appear on a TDBNavigator object. The following table lists all the button types, their corresponding TNavigateBtn values, and the action associated with each button:

Value	Button	Purpose
nbFirst	First	Sets the current record to the first record in the dataset, disables the First and Prior buttons, and enables the Next and Last buttons if they are disabled.
nbPrior	Prior	Sets the current record to the previous record and enables the Last and Next buttons if they are disabled.
nbNext	Next	Sets the current record to the next record and enables the First and Prior buttons if they are disabled.
nbLast	Last	Sets the current record to the last record in the dataset, disables the Last and Next buttons, and enables the First and Prior buttons if they are disabled.
nbInsert	Insert	Inserts a new record before the current record and sets the dataset into Insert and Edit states.
nbDelete	Delete	Deletes the current record and makes the next record the current record.
nbEdit	Edit	Puts the dataset into Edit state so that the current record can be modified.
nbPost	Post	Writes changes in the current record to the database.
nbCancel	Cancel	Cancels edits to the current record, restores the record display to its condition prior to editing, and turns off Insert and Edit states if they are active.
nbRefresh	Refresh	Refreshes the buffered data in the associated dataset.
nbApplyUpdates	ApplyUpdates	Writes changes for all the changed records (inserted, deleted or edited) to the database.
nbCancelUpdates	CancelUpdates	Cancels edits for all edited records, restores the record display to its condition prior to editing, and turns off Insert and Edit.
