Dear Experts

There is a grid on form with allowaddnew=.t.
I have following codes to populate

select table1
index on sno to table11

thisform.grid1.recordsource="Table1"
thisform.grid1.column1.controlsource="Table1.sno"
thisform.grid1.column2.controlsource="Table1.name"
thisform.grid1.column1.setfocus
thisform.refresh

I want to stop dnarrow in grid.
I want to use only Enter key to go to next row.

Please help
