Question

I want to minimize and maximize manually in C#.net.
I changed form’s BorderStyle into none.
So there are no maximize,minimize and close button from bar.
I want to manually create with button like those functions.
I want to do three functions in button click events.

Answer 1

You have to set the forms WindowState property something like this:

In Windows Forms:

private void button1_Click(object sender, EventArgs e)
{
    this.WindowState = FormWindowState.Minimized;
}

In WPF:

private void button1_Click(object sender, RoutedEventArgs e)
{
    this.WindowState = WindowState.Minimized;
}
