Добрый день!
Столкнулся с такой проблемой.
Есть UserControl в котором находилась круговая диаграмма. Все работало хорошо, пока не потребовалось менять GUI для этого UserControl.
Я выделил все это в ControlTemplate и диаграмма перестала показываться. ToolTip над ней показывается но самой нет. И при изменении значений в ItemsSource вылетает исключение KeyNotFoundException.

Здравствуйте, Аноним, Вы писали:
А>Вот диаграмма.
А>А> ...
А> ItemsSource="{Binding TimeCollection}"
А> DependentValueBinding="{Binding Lines}"
А> IndependentValueBinding="{Binding DisplayName}"/>
А>
Почему-то мне кажется, что дело именно в этих 3-х строках. нельзя ли посмотреть на TimeCollection?

Не думаю, что в этом дело. Раньше этот код работал без проблем.
Вот
private readonly ObservableCollection<TimeElement> _timeCollection = new ObservableCollection<TimeElement>();
public ObservableCollection<TimeElement> TimeCollection
{
get { return _timeCollection; }
}
public class TimeElement: INotifyPropertyChanged
{
private string _displayName;
public string DisplayName
{
get { return _displayName; }
set
{
_displayName = value;
var handler = PropertyChanged;
if (null != handler)
handler.Invoke(this, new PropertyChangedEventArgs("DisplayName"));
}
}
public int Lines
{
get { return _lines; }
set
{
_lines = value;
var handler = PropertyChanged;
if (null != handler)
handler.Invoke(this, new PropertyChangedEventArgs("Lines"));
}
}
private int _lines;
public event PropertyChangedEventHandler PropertyChanged;
}

Спасибо, но судя по всему проблема не в этом.
Сейчас запустил проект на другом компе — все работает нормально.
Буду смотреть чего не так на моем)))
