我正在尝试从背后的代码中访问数据板内的控件。我正在使用C＃和UWP(通用Windows平台(。DataTemplate用于SyncFusion控件(TileView(。我的XAML代码是：

我需要访问的控件是一个名为" hideendid"的隐藏文本块(位于一个名为" buttonsstack"的stackpanel内部(。
有人知道我如何访问DataTemplate内部的控件吗？我尝试了我能想到的一切：(
预先感谢。
通常可以使用VisualTreeHelper检索数据站板的元素。我创建了一个样本并在此处上传，请告诉我是否有帮助。
注意：我为同步。
这个问题的答案可以在另一个问题上找到。无法访问控件的原因是因为您创建了此数据模板的多个实例，其中控件的名称将相互冲突。
要解决它，您必须使用一种方法来获取所有孩子，然后搜索您尝试访问的控制。完整的解决方案可以在上面发布的链接中找到。
