MdiClient in a SplitPanel

[gilbert]

Hello.

I am using .Net 2.0, C#. and am trying to put a MdiClient control into
a SplitPanel of a SplitContainer.

First, I put a SplitContainer called splitContainer1 into the form.

In the Form_Load handler, I use the following,

MdiClient mdiClient = new MdiClient();
mdiClient.BackC olor = Color.White;

Form mdiForm = new Form();
mdiForm.Control s.Add(mdiClient );
ChildForm childForm1 = new ChildForm();
childForm1.MdiP arent = mdiForm;
childForm1.Show ();

Form childForm2 = new Form();
childForm2.MdiP arent = mdiForm;
childForm2.Show ();

splitContainer1 .Panel1.Control s.Add(mdiClient );

It seems good at the beginning, however, when I click on a child form,
its titlebar does not highlight. I can still move the child forms, but
their titlebars are not highlighting. Do you know how to solve this
problem? Thank you very much!
