I’ve blogged before that in solutions that share xaml between DLLs the XAML UI Designer can cause problems by locking files and blocking builds. The fastest solution is usually to kill off the designer process. Here is a bit of powershell to do just that;
Get-Process -Name XDesProc | Stop-Process
The ListPicker in Wp7 Toolkit allowed you to specify how many items could be shown before it went into full-screen mode. Quite correctly that has been removed and is now hardcoded to 5. Well, rules are there to be broken, and if you *really* need to workaround the problem then you can try the following (it works at the moment, may not work in the future)
Type type = MyListPicker.GetType();
PropertyInfo itemCountThreshold = type.GetProperty("ItemCountThreshold");
itemCountThreshold.SetValue(MyListPicker, 20);
Looking at the reflection code I released that I hadn’t actually done anything sneaky. So I replaced it with the following…more graceful code;
MyListPicker.SetValue(Microsoft.Phone.Controls.ListPicker.ItemCountThresholdProperty, 20);
