I would like to ask a 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 f
Form.WindowState Property
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.windowstate%28v=VS.90%29.aspx
public FormWindowState WindowState { get; set; }
For example -
var form = new Form();
form.WindowState = FormWindowState.Maximized;
form.WindowState = FormWindowState.Minimized;
form.WindowState = FormWindowState.Normal;
However, if you are in the code behind on the main form (or any form) just do this -
WindowState = FormWindowState.Maximized;
