Select all rows in TFMXGrid

How do you select all rows in a TFMXGrid ?

In these test cases, all rows get selected except for the first row

1) FilesGrid.SelectRows (-1,ClientDataSet1.RecordCount);

2) FilesGrid.SelectRows (0,ClientDataSet1.RecordCount);

3) FilesGrid.SelectRows (1,ClientDataSet1.RecordCount);

If I do this ...
only rows 5 and 6 get selected

So - how can I select all rows including the first row ?

Than you
