阅读更多关于 Calculate and draw route on Bing Maps control

问题 in my app for WP7(mango) I need to navigate the user from one point to another. I know there is the Map control that lets you draw staff on it, but how do you ask it to draw the path for you? (based on the specified destination & user's current location - but that keeps changing so how do you update the route if he goes of the way?) 回答1: To update the map with the users current location, use the GeoCoordinateWatcher and update the position of a databound Pushpin as it changes. Remember to set

Add a Load More Button at the end of ListBox without losing Virtualization?

阅读更多关于 Add a Load More Button at the end of ListBox without losing Virtualization?

I know by editing the ListBox 's default style like this, I can have a Button at the very end of the ListBox . <ScrollViewer x:Name="ScrollViewer" ...> <StackPanel> <ItemsPresenter /> <Button /> </StackPanel> </ScrollViewer> However, doing this will break the ListBox 's Virtualization and the rendering time becomes really long. All I can think of is, Create a dummy item and add it to the end of my item collection in the viewmodel, and have a Visibility property in the dummy object called ButtonGridVisibility and set it to Visibility.Visible . In my ListBox 's ItemTemplate , have two Grids .

WP7: Is it possible to intercept the backstack before the journal thumbnail is created/stored

阅读更多关于 WP7: Is it possible to intercept the backstack before the journal thumbnail is created/stored

You all know the Windows Phone backstack right. If you go through some apps, tap the Home key after starting each app. Now tap and hold the Backkey to see the Backstack. You can now see some small images of your apps, and can pick which one to go to right. Question: Is it possible to intercept before the backstack image is created? I have tried to blur my page in various events (include OnNavigatingFrom) to no avail. My guess is some other event (probably something we don't have access to) is triggered and a bitmap is created, because when you use the Backstack to navigate you can just see a

What's the best way to determine if the user has set the "24-hour clock" setting to true in Settings-Date+Time on the Windows Phone ? Can I get this information through the CurrentCulture (CultureInfo) ? I had no luck in finding it. user994597 The system clock type can be retrieved using: string clockType = Windows.System.UserProfile.GlobalizationPreferences.Clocks.FirstOrDefault(); This will return the string 24HourClock if the 24 hour setting is on in the device settings or 12HourClock if the setting is off. On the back of Dennis' answer, you should be able to determine 24-hour time using
