好吧我的问题是我动态生成了一些元素,因为链接到一个数组(对于数组中的每个元素,XAML中都有另一个项目)。我使用TreeView控件,albiet跟随一个在线示例(到目前为止一直运行良好)。
在此示例中,这些群组是家庭群体,并且在每个群组中......好吧,它更容易在图像here中显示。 Family是一个包含ObservableCollection of FamilyMembers的类,它们都用于填充TreeView。
这是主要业务:

这一切都很好,但这是我的问题:如果家庭成员是男性,我有男性形象,如果家庭成员是女性,我有男性形象。我不知道如何根据此标准获取元素以设置图像。如您所见,目前图像是静态的。
