navigation

问题 Hello, I'm working in a simple Windows 8 application with xaml and c#. I'm using the VS 2012 templates to create pages, with navigation system included. I'm loading a lot of data, so I decided to add a loading page with a ProgressRing and navigate to the first Application page when loading data is finished: //loading page protected async override void OnNavigatedTo(NavigationEventArgs e) { ... await topCookerManager.GetBlogsAsync(); this.Frame.Navigate(typeof(MainPage)); ... } It works well

问题 I have a header bar (kinda like menu) and 4 fragments (MAIN, A, B, C) from which the MAIN should be 'main/root' fragment for backstack. Problem i have is when user via menu goes for example MAIN > A > B > C. If i simply use backstack it will go in reverse order which i don't want. I need back button to go back to MAIN no matter how user navigated to one of those 3. My current code (which is wrong, it quits app when not in MAIN and current fragment is switched from other non-MAIN fragment)

问题 Is it possible with Fancybox 2.0 to always keep the image gallery navigation arrows visible? Rather than just visible on hover. 回答1: For fancybox v2.x you may use these CSS inline declarations (after you have linked to the jquery.fancybox.css file): <style type="text/css"> .fancybox-next span { left: auto; right: 20px; } .fancybox-prev span { left: 20px; } </style> UPDATE (July 12, 2012) : Since Fancybox v2.0.6+ just need to add this css declaration instead .fancybox-nav span { visibility:

问题 Here's what I've got so far: fiddle 2 problems with it though: I've hard-coded the width of each li to 33% , which I'd prefer not to do so that I can easily add more items. I want to put some spacing between each item (a gap in the background color), but as soon as I add a margin, one item will be bumped down a line. How do I get around that? #main-nav { list-style: none; margin: 0; padding: 0; width: 100%; overflow: auto; } #main-nav li { float: left; width: 33%; height: 25px; text-align:

问题 I was working on an application with login and after login there are categories listed. And under each category there are some items listed horizontally. The thing is after login, main page appears and everything is listed great. When you click on an item it goes to detailed screen but when you try to go back it just crashes.

问题 I got a problem trying to find an element declared in DataTemplate, that after was applied like a ContentTemplate to TabItem object. I saw that there is already some solutions in regard of this problem, but no one of them actually works in my case, and I would like to understand why (obviously I make mistake in some place) Here is a sample code: <DataTemplate x:Key="TabItemDataTemplate"> <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Name="templateGrid"> <Grid.RowDefinitions>
