How popular is a Grid with a list of users using LiveBindings?
Having created a type:
TPessoa = class
private
FId: integer;
FNome: string;
FDataNascimento: TDate;
public
property Id: integer read FId write FId;
property Nome: string read FNome write FNome;
property DataNascimento: TDate read FDataNascimento write FDataNascimento;
end;
I've added some components to the form:
TStringGrid TDataGeneratorAdapter TAdapterBindSource TBindNavigator
BindingListwasautomaticallycreated.
TofeedtheAdapterBindSourceIcreatedaTObjectBindSourceAdaptertypevariableinmyform:
TMainForm = class(TForm)
strgList: TStringGrid;
DataGeneratorAdapter: TDataGeneratorAdapter;
AdapterBindSource: TAdapterBindSource;
bindNav: TBindNavigator;
BindingsList: TBindingsList;
LinkGridToDataSourceAdapterBindSource: TLinkGridToDataSource;
procedure FormCreate(Sender: TObject);
procedure FormClose(Sender: TObject; var Action: TCloseAction);
procedure AdapterBindSourceCreateAdapter(Sender: TObject;
var ABindSourceAdapter: TBindSourceAdapter);
private
FPessoas: TObjectBindSourceAdapter<TPessoa>;
end;
...
procedure TMainForm.AdapterBindSourceCreateAdapter(Sender: TObject;
var ABindSourceAdapter: TBindSourceAdapter);
begin
ABindSourceAdapter := FPessoas;
end;
My difficulty is this list is popular.
For this I thought:
procedure TMainForm.FormCreate(Sender: TObject);
var
index: integer;
pessoa: TPessoa;
begin
FPessoas := TObjectBindSourceAdapter<TPessoa>.Create(self);
for index := 1 to 100 do
begin
FPessoas.Append;
pessoa := TPessoa.Create;
pessoa.Id := index;
pessoa.Nome := 'Nome ' + index.ToString();
pessoa.DataNascimento := StrToDate('01/01/2000') + index;
FPessoas.SetDataObject(pessoa);
end;
end;
