Grid on window form

I am using VS 2008 and I try to create a new window form application. By
default, no grid line is shown on the window form. So I go to
tools->options->window form designer to set property Layout = "Snap to Grid",
ShowGrid= "True" and SnapToGrid="True". Then I go back to the window form and
make sure the property DrawGrid is also set to True. However, no grid is
shown on the form even through I closed and reopen the whole VS 2008.

By the way, I try to drag some new control to the window form and found
there is something strange. For example, I drag a splitcontainer to the form
but the splitter dash line is missing. Is there is anything wrong with my IDE
setting.
