.NET DataGridView Skinning Issue

I'm cannot exactly describe what circumstances cause this issue, which is why I'm posting to the forum and not creating an IssueTrak ticket... but I wanted you to be aware of it nonetheless.  I think it has something to do with setting the column AutoSizeMode to Fill - but you can see that the vertical scrollbar renders ok, but the horizontal is not skinned

this:

 

#region ScrollBar Skin
            if (this.Visible)
            {
                dgvGroups.VirtualMode = false;
                dgvUsers.VirtualMode = false;
                try
                {
                    for (int i = 0; i < 20; i++)
                    {//Vertical ScrollBar
                        dgvGroups.Rows.Add(new object[] { "", "", "", "" });
                        dgvUsers.Rows.Add(new object[] { "", "", "", null, "", "" });
                    }
                }
                catch{}
                tabGroupUser.SelectedTab = tabUsers;
                Common.OnVisibleChanged(tabUsers);
                //Horizontal ScrollBar
                this.Width = 630;
                this.Left = (Owner.Width - this.Width) / 2;
                tabGroupUser.SelectedTab = tabGroups;
                dgvGroups.VirtualMode = true;
                dgvUsers.VirtualMode = true;
            }
            #endregion

 

Common.cs:

 

public static void OnVisibleChanged(Control ctrl)
        {
            //Apply Skin 
            if (ctrl.Visible)
            {
                Common.skinFramework.ApplyWindow(ctrl.Handle.ToInt32());
                ctrl.BackColor = Common.skinFramework.GetColor(XtremeSkinFramework.XTPColorManagerColor.STDCOLOR_BTNFACE);
            }
        }
