我的代码:MessageDialog在Windows 8 XAML
MessageDialog msg = new MessageDialog("Are you sure to cancel the booking?", "Confirmation");
msg.Commands.Add(new UICommand("Confirm", new UICommandInvokedHandler(CommandHandler)));
msg.Commands.Add(new UICommand("Cancel", new UICommandInvokedHandler(CommandHandler)));
msg.DefaultCommandIndex = 1;
msg.CancelCommandIndex = 1;
await msg.ShowAsync();
private async void CommandHandler(IUICommand command)
{
var commandLabel = command.Label;
switch (commandLabel)
{
case "Confirm":
CancelBookingTickets();
break;
case "Cancel":
break;
}
}
protected async void CancelBookingTickets()
{
MessageDialog msg1 = new MessageDialog("The cancellation process is complete", "Complete");
await msg1.ShowAsync();
}
我想使用嵌套MessageDialog框在我的Windows 8的XAML应用程序,但是当我到达的msg1.ShowAsync()
,它激发一个异常说:“访问被拒绝”。
有人可以帮我解决这个问题吗?
