How to increase width of the Vertical ScrollBar in VS 2005 ?

I am using dataGridview of VS 2005 in my application.
My application will be used for Touch screen.

So when user needs to scroll down with his fingers,
then it is difficult to do with the default width.

In VB.NET 2003 , I used datagrid and in that i used

"grid.Controls(1).Width =30"

to increase the width of Verticle scroll bar.

But the same property is not working here...

So, I would like to know that how can I increse the width of scroll bars in DataGridview.

Thanks in advance.
