How to dock datagrid in a form?

[DBC User]

I am trying to dock a datagrid in a form and it does dock to fill but
I want to extend all the columns I have to fit on the whole screen.
But it is showing the columns and then leaving bunch of space empty
and it look bad. Could someone help me?

Thanks and autosize mode parameters set to fill fixed the problem.
Thanks again for the suggestion.
