Declaration
procedure AppendBlank;
Description
Places a new, empty record buffer in Edit mode. After replacing field data, either through visual data controls or through code, calling the Commit method (or Post method) will physically add the new record to the end of the table and update all open indexes. Calling the Cancel method will abort the append process.
This method is identical in behavior to the Append method and TDataSet's Insert method.
Under TApolloTable, this method is simply mapped to Delphi / C++Builder's own TDataSet.Insert method, and is simply included for compatibility purposes.
Delphi Example
// NOTE: Place 3 buttons (ADD, SAVE, & CANCEL) and some bound text controls on a form.
// Begin Edit Process with a form full of TDBEdit controls
procedure TForm1.bAddClick(Sender: TObject);
begin
ApTbl.AppendBlank; { Could also use ApTbl.Insert }
end;
// Save new record from data in ghost record
procedure TForm1.bSaveClick(Sender: TObject);
begin
ApTbl.Commit; { Could also use ApTbl.Post }
end;
// If user clicks 'Cancel' button, bail out without saving record data
procedure TForm1.bCancelAddClick(Sender: TObject);
begin
ApTbl.Cancel;
end;
C++Builder Example
/* NOTE: Place 3 buttons (ADD, SAVE, & CANCEL) and some bound text controls on a form. */
// Begin Edit Process with a form full of TDBEdit controls
void __fastcall TForm1::bAddClick(TObject *Sender)
{
ApTbl->AppendBlank(); // Could also use ApTbl->Insert()
}
// Save new record from data in ghost record
void __fastcall TForm1::bSaveClick(TObject *Sender)
{
ApTbl->Commit(); // Could also use ApTbl->Post()
}
// If user clicks 'Cancel' button, bail out without saving record data
void __fastcall TForm1::bCancelAddClick(TObject *Sender)
{
ApTbl->Cancel();
}
