I figured it out.
I've been using the StrataFlix paradigm to recreate my application interface and functionality. It has been a marvelous learning curve.
What I did to solve the problem was to remove the _MDIClient definition from the parent/container form. I removed the local variable (_MDIClient) and replaced the OnLoad code as follows:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
//-- Set the MDI backcolor to white
//_MDIClient.BackColor = Color.FromName("Control");
//-- Add the MDI
//Controls.Add(_MDIClient);
this.IsMdiContainer = true;
XtraTabbedMdiManager mMDIManager = new XtraTabbedMdiManager();
mMDIManager.MdiParent = this;
mMDIManager.Appearance.BackColor = Color.FromName("Control");
}
This works like a charm! Hope this helps someone else out there.
