Windows User control form

Windows User control form

I am creating one user control in windows form. It is some data entry
form. The application opens in minimize mode initially. And the from looks
good in minimization mode. But when i maximize the form is not getting
filled up. I mean the there is lot of room in maximize mode. The form
should grow size according to minimize or maximize. The form has tab
control, group box and grid view. thanks.
