Here's a link displaying the issue: http://imageshack.us/f/844/pa82.png/
Basically, I've created a form that is full screen, set that form to a MDIContainer so that I can add other forms inside of it, and also remove them.
As soon as I set the MDIContainer the form's appearance started giving me issues, such as it changed the background color to gray and added that border. I've fixed the background color by changing the MDIClient background color (found via a foreach statement, shown below), but I can't find any border settings...
foreach (Control control in this.Controls)
{
MdiClient client = control as MdiClient;
if (!(client == null))
{
client.BackColor = Color.Black;
break;
}
}
Any idea what that thing is, and how I can remove/hide it?
