During the creation of a Windows Phone 7 application for Trix I wanted to give the user the chance to add a reminder for a concert of his choice. With some example code available, the implementation was smooth and easy. Until I ran into this error while testing the app:
ArgumentOutOfRangeException was unhandled Specified argument was out of the range of valid values. Parameter name: Title
Since I selected an item with a very long title, it was quite clear what the problem was. A small search on MSDN learned me that the maximum length for this property is 63 characters.
