这一切都是因为图片而发生的，怎么打呢？

listbox和groupbox - 如果需要我可以提供他们的样式

我使用转换

<GroupBox Header="Сопровождающие" Width="300" HorizontalAlignment="Stretch" x:Name="GroupBox" Background="Transparent" Height="{Binding ElementName=list_category, Converter={StaticResource ConSetHeigthKey}}">

转换器：

public class ConSetHeigthTrainer : IValueConverter
        {
            public object Convert(object value, Type targetType, object parameter,
                                  CultureInfo culture)
            {
                try
                {
                    return (value as System.Windows.Controls.ListBox).ActualHeight-20;
                }
                catch (Exception Exception) { return (value as System.Windows.Controls.ListBox).ActualHeight - 20; }
            }

            public object ConvertBack(object value, Type targetType, object parameter,
                                      CultureInfo culture)
            {
                throw new NotImplementedException();
            }
        }

如何安排元素？
