Need help to impliment Splitter in windows form using VS2010

Hi,

I am using splitter in form which contain two different information using group boxes.
Splitter.Pane11 contains groupbox1 and second Panle2 splitter.panel2 contains another groupbox2.
both group box contains other controls like text box, grid and button.etc..

If we maximize or re-size the form or splitter panels I am not able to re size other controls size depending on group or Splitter size.I checked with anchoring property but I am not getting scrolling property in maximize mode.

And also if user double clicks on Splitter then it will expand the Splitter.Pane11 and again double click collapse the Splitter.Pane11.

Please help me to solve this problem.

Thanks in advance.
