WPF 列表视图加载时排序

【中文标题】WPF 列表视图加载时排序【英文标题】：WPF List View Sort on Load 【发布时间】：2009-02-26 18:38:49 【问题描述】：问题来了：
我想在 ListView 首次加载时对其进行排序。 我已经实现了可以在列表视图中排序的功能，如果标题列 在 ListView 中被点击。
我找不到合适的事件来调用我的排序函数。 我尝试使用 UserControl 和 Loaded 事件的 OnInitialized 但似乎列表视图是 当我调用这些函数时没有填充。
我尝试了 ListView 的 GotFocus。它可以工作，但我必须点击窗口才能完成排序。
我希望在加载 ListView 后立即进行排序。
我在列表视图中使用 XML 数据绑定。 ListView 是用户控件的一部分。用户控件托管在 MMC 应用程序中。
如果您需要任何其他信息，请告诉我。
公共类 SortableGridViewColumn : GridViewColumn 公共字符串 SortPropertyName 获取返回（字符串）GetValue（SortPropertyNameProperty）； 设置 SetValue(SortPropertyNameProperty, 值);

【参考方案1】：我终于能够解决它。 我不得不在 ListView ItemSource 上使用转换器。然后在 Convert Function 上对 List 进行排序。
