提高chatBubble_Tap事件時,可以嘗試提高您r這樣的事件:
// make your eventhandler in Parent Page public and static so it will be available thru all the App
public static void chatBubble_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
// your code
}
// then in your UserControl you should be able to call it like this:
private void ChatBubbleControl_Hold_1(object sender, System.Windows.Input.GestureEventArgs e)
{
YourPage.chatBubble_Tap(sender, e);
}
這種情況取決於你在Tap事件中有什麼(並非所有事情都可以在靜態方法中)。 。
您還可以通過你的頁面的處理程序,以你的用戶控件,然後從處理程序調用你的點擊事件(在這種情況下,點擊事件可以是public
(非靜態)簡單的情況下,可以是這樣的:
// your Control in MainPage (or other Page)
<local:myControl x:Name="yourControl" VerticalAlignment="Center" Grid.Row="1"/>
// initializing control and event to be invoked:
public MainPage()
{
InitializeComponent();
yourControl.pageHandler = this;
}
public void second_Click(object sender, RoutedEventArgs e)
{
// something here
}
// and the control code:
public partial class myControl : UserControl
{
public Page pageHandler;
public myControl()
{
InitializeComponent();
myButton.Hold +=myButton_Hold;
}
private void myButton_Hold(object sender, System.Windows.Input.GestureEventArgs e)
{
if (pageHandler is MainPage) (pageHandler as MainPage).second_Click(sender, e);
}
}
第三個選擇是傳遞一個Action
您的控制(在這種情況下,事件可以是私有的):
// code in MainPage (or your Page)
public MainPage()
{
InitializeComponent();
yourControl.myAction = second_Click; // setting an action of Control
}
private void second_Click(object sender, RoutedEventArgs e)
{
// something here
}
// and the Control class
public partial class myControl : UserControl
{
public Action<object, System.Windows.Input.GestureEventArgs> myAction;
public myControl()
{
InitializeComponent();
myButton.Hold +=myButton_Hold;
}
private void myButton_Hold(object sender, System.Windows.Input.GestureEventArgs e)
{
if (myAction != null) myAction.Invoke(sender, e);
}
}
