I have a form with a grid

Also I have a textbox where I add a name

Buffermode is 4 on cursor

When I add a record and then tableupdate (), the name appears on the grid
That's ok

But when I add a name, even if I don't not press tableupdate (),
the name also appears on the GRID

That's bad

I have to close de form and execute it again, so the name will not be on GRID

How can I solve it ?
