我正在尝试以编程方式将UIElements 添加到LongListSelector项目中。我已经为页眉、页脚、项目等创建了模板。
现在我正在做这样的事情（列表项模板）：
<DataTemplate x:Key="listItemTemplate">
<ContentPresenter Content="{Binding ItemContent}"></ContentPresenter>
</DataTemplate>
在模型内部，我将 ItemContent 分配给一个网格，在该网格上添加不同的 UI 元素。我真的不知道这是否是这样做的方法，或者这是否可能在 LongListSelector 上但滚动列表时我得到一个“参数不正确”。异常（起初，一切似乎都很好，添加的所有元素看起来都很好）。我尝试了不同的方法，但都没有奏效，我觉得我只是在没有特定想法的情况下随机尝试解决方案。有没有人设法通过使用 LongListSelector 做到这一点（任何建议将不胜感激）？
