[Tips] [Windows Phone 7 (Beat)] 如何讓硬體的返回鍵不作用

Windows Phone 7上硬體有一個返回按鍵，某些時候我們需要讓它不起作用。

這時候可以先註冊BackKeyPress ，再把它的Cancel設為true就行了。

public Mianpage()
{
    InitializeComponent();
    this.BackKeyPress += new EventHandler<System.ComponentModel.CancelEventArgs>(PhonePage1_BackKeyPress);
}

void PhonePage1_BackKeyPress(object sender, System.ComponentModel.CancelEventArgs e)
{
    e.Cancel = true;
}
