Scroll bar doesn't stay within client area in Winforms tab control

I have a TabControl, to which I am programmatically adding a Form with a GridView control on it to the Tab Controls Controls collection. The result looks like this:

enter image description here

The GridView in the illustration actually has about 150 columns... When I use the horizontal scroll bar to scroll to the right, I get this:

enter image description here

Notice that the scroll-bar is not staying in the visible client area of the tab. Instead, the scroll bar is assuming the width of the embedded form.

How do I get the scroll bar to assume the width of the visible client area in the tab?

Here is my code. PcmEditorForm is just a blank form, with FormBorderStyle set to none, and there is some code that sets the number of rows and columns in the grid that's not shown here:

    private void LoadEditorTab()
    {
        var editor = new PcmEditorForm();
        var grid = new GridView();
        editor.Width = grid.Width;
        editor.Height = grid.Height;
        editor.Controls.Add(grid);
        editor.AutoScroll = true;
        editor.Anchor = AnchorStyles.Left | AnchorStyles.Top;
        tabEdit.Controls.Clear();
        editor.TopLevel = false;
        editor.Visible = true;
        tabEdit.Controls.Add(editor);
    }

Why don't you just dock the editor in the tabEdit.

private void LoadEditorTab()
    {
        var editor = new PcmEditorForm();
        var grid = new GridView();
        grid.width=editor.width
        grid.Anchor= AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right;
        editor.Controls.Add(grid);
        tabEdit.Controls.Clear();
        editor.TopLevel = false;
        editor.Visible = true;
        editor.dock=DockStyle.Fill;  // Dock the editor
        tabEdit.Controls.Add(editor);
    }
