You mean something like this
Code: [Select]
DBF1.Filter := 'Field1="SomeValue"';
DBF1.Filtered := True;

thank , but with this, there an "violation error"

i'm found this

Code: [Select]procedure TForm1.MybaseFilter(DataSet: TDataSet;
  var Accept: Boolean);
begin
  Accept:=Mybase.FieldByName('Field1').AsInteger>=2;
end;

and it's work fine !!
