Maximizing a MDI Parent Form???

[kleinma]

maximize it from where?

you could click the maximize button in the upper right, but I image that isn't exactly what you mean right?

If you want to do it via code, then it depends on where the code is running from.

If you want to maximize the MDI Parent from code in the parent itself, its simply

Me.WindowState = FormWindowState.Maximized

From an MDI Child form

Me.MdiParent.WindowState = FormWindowState.Maximized
