frameworkTemplate.FindName Method (String,frameworkElement)为此，您需要：
private childItem FindVisualChild<childItem>(DependencyObject obj)where childItem : DependencyObject{ for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++) { DependencyObject child = VisualTreeHelper.GetChild(obj, i); if (child != null && child is childItem) return (childItem)child; else { childItem childOfChild = FindVisualChild<childItem>(child); if (childOfChild != null) return childOfChild; } } return null;}然后：
for (int i = 0; i < Game_ScrollViewer_online.Items.Count; i++){ ListBoxItem GameListBoxItem = (ListBoxItem)(Game_ScrollViewer_online.ItemContainerGenerator.ContainerFromIndex(i)); ContentPresenter contentPresenter = FindVisualChild<ContentPresenter>(GameListBoxItem); DataTemplate myDataTemplate = contentPresenter.ContentTemplate; Button tempBut = (Button) myDataTemplate.FindName("Current_game_button", contentPresenter); //Do stuff with button}要解决这样的缺失
FindName用法
FindDescendant：
public T FindDescendant<T>(DependencyObject obj) where T : DependencyObject{ if (obj is T) return obj as T; int childrenCount = VisualTreeHelper.GetChildrenCount(obj); if (childrenCount < 1) return null; for (int i = 0; i < childrenCount; i++) { DependencyObject child = VisualTreeHelper.GetChild(obj, i); if (child is T) return child as T; } for (int i = 0; i < childrenCount; i++) { DependencyObject child = FindDescendant<T>(VisualTreeHelper.GetChild(obj, i)); if (child != null && child is T) return child as T; } return null;}
