在WPF中是否有任何替代选项,此标记的性质是在执行任何特定操作之前启用确认对话框。
这个标签在silverlight支持下,但不幸的是,它似乎在WPF下失踪了。不确定这个Prism团队是否意外地错过了什么。上述标签的最佳替代方案是什么?
你基本上必须创建自己的。但是,有一个例子,我发现之前我找到了一个人。我修改了Prism的交互类很多,所以我的ModalPopupAction可能与你需要的有点不同。所以请查看此链接并下载他的示例。它有WPF的实现!
Prism: InteractionRequest and PopupModalWindowAction for WPF applications
如果你想知道......我的ModalPopupAction看起来像这样(但它需要我的其他一些类)
public class ModalPopupAction : TriggerAction<FrameworkElement>
{
public UserControl InteractionView
{
get { return (UserControl)GetValue(InteractionViewProperty); }
set { SetValue(InteractionViewProperty, value); }
}
// Using a DependencyProperty as the backing store for PopupDialog. This enables animation, styling, binding, etc...
public static readonly DependencyProperty InteractionViewProperty =
DependencyProperty.Register("InteractionView", typeof(UserControl), typeof(ModalPopupAction), new UIPropertyMetadata(null));
protected override void Invoke(object parameter)
{
InteractionRequestedEventArgs args = parameter as InteractionRequestedEventArgs;
if (args == null)
return;
// create the window
ModalPopupDialog dialog = new ModalPopupDialog();
dialog.Content = InteractionView;
// set the data context
dialog.DataContext = args.Interaction;
// handle finished event
EventHandler handler = null;
handler = (o, e) =>
{
dialog.Close();
args.Callback();
};
args.Interaction.Finished += handler;
// center window
DependencyObject current = AssociatedObject;
while (current != null)
{
if (current is Window)
break;
current = LogicalTreeHelper.GetParent(current);
}
if (current != null)
dialog.Owner = (current as Window);
dialog.ShowDialog();
dialog.Content = null;
dialog.DataContext = null;
args.Interaction.Finished -= handler;
}
}
