i am able to do it when i am in that form's code page as follows, but i can not do that when i pass the form as a variable to another class.
namespace WindowsApplication8
{
partial class Form1
{
/// <summary>

{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

now i added one more button and a class file to show what i said, it worked however, i think there is a problem with my application since it is a mobile device application unlike the windows application here.
