WinForms SplitContainer and its spacing and resizing

Question

I seem to have a lot of trouble getting a SplitContainer adjusted the way I like it. I have the following form called frmMain:

frmMain Screenshot

In the form Load code I have to following code:

With MainContainer
    .IsSplitterFixed = True
    .Dock = DockStyle.Fill
    .SplitterDistance = 200
    .FixedPanel = FixedPanel.Panel1
    .Panel1.BackgroundImage = Resources.My.Resources.ResourceFile._001
    .Panel2.BackColor = Color.White
    .Panel2.AutoScroll = True
End With

When I run the code I get the following:

frmMain (Compiled)

I want to remove the gray splitter since there is no use to it. Is this a common beauty bug and is it possible to remove it?

My second problem with the SplitContainer is if I resize my window, the backgroundImage in Panel1 and the white color in Panel2 don't adjust with the window. I searched high and low to the Resize code but I can't find it. The Panel2 has User Controls, eg. Dashboard and are loaded this way: MainContainer.Panel2.Controls.Add(Dashboard).

Is it also possible that Panel2 automatically adjusts to the weidht of the window so thay you only have a hortizontal scrollbar?

Thank you for reading my question and hopefully you can help me solve my problems with the SplitContainer. Have a nice day.

If you don't want the user to see or move the splitter, why use a split container? As an alternative, consider using a TableLayoutPanel configured with 1 row and 2 columns. The first column would be an absolute 200 px wide while the second column would be set to 100% wide. In each of the two cells, you could place a panel which is docked and set to have a margin of 0,0,0,0.

While I did not mock up your current solution, I was not able to replicate these problems with a quick mock up of the solution I proposed above. With regards to auto-scrolling, the only reason that scroll bars should appear would be if a control is off the edge of the screen or the available screen space is less than the minimum size of the panel.
