How to trigger the event associated with maximize in C#

Question

Consider the following code:

Window myWindow = new MyWindowSubclass();
myWindow.BringIntoView();
myWindow.Show();

// Code which is effective as pressing the maximize button

Also, how to detect if the window is indeed in maximized state.

Do you want to target Windows.Forms or WPF? You code looks like WPF, but your question has both tags. — Frédéric Hamidi, May 04 '11 at 14:31

In WPF, you can use the WindowState property:

myWindow.WindowState = WindowState.Maximized;

You can of course query that property to obtain the current window state:

if (myWindow.WindowState == WindowState.Maximized) {
    // Window is currently maximized.
}

This is what I needed :). BTW, its ok to maximize a maximized window right? – Shamim Hafiz - MSFT May 05 '11 at 06:30

@Gunner, maximizing a already maximized window is okay: it will have no effect. – Frédéric Hamidi May 05 '11 at 06:32

For WinForms, you can use

bool maximized = this.WindowState == System.Windows.Forms.FormWindowState.Maximized;

to test if the window is maximized.

The SizeChanged and Resize events should capture all changes to the window state.

In WinForms, do

// Code which is effective as pressing the maximize button
myWindow.WindowState = FormWindowState.Maximized;

Of course you can test it the same way:

if (myWindow.WindowState == FormWindowState.Maximized) { ... }
