我有一個 WPF 頁面，其中有幾個ListViews. 我想在單擊時對列表進行排序headers，這沒有問題，但現在我為每個 ListView 創建一個單獨的函數，我想創建一個通用函數。假設我想替換它：contexte.ListeDesAssemblagesView.SortDescriptions.Clear();contexte.ListeDesAssemblagesView.SortDescriptions.Add(monsort);通過類似的東西：sender.ItemsSource.SortDescriptions.Clear();sender.ItemsSource.SortDescriptions.Add(monsort);編輯：這是由于 mm8 而修改的我的函數代碼。void GridViewColumnHeaderClickedHandler(object sender, RoutedEventArgs e){ GridViewColumnHeader headerClicked = e.OriginalSource as GridViewColumnHeader; ListSortDirection direction; ListView listView = sender as ListView; ICollectionView view = CollectionViewSource.GetDefaultView(listView.ItemsSource); string header = ""; if (headerClicked.Column.DisplayMemberBinding != null) { header = ((System.Windows.Data.Binding)headerClicked.Column.DisplayMemberBinding).Path.Path; } else { try { DataTemplate cellTemplate = headerClicked.Column.CellTemplate; Grid grid = cellTemplate.LoadContent() as Grid; TextBlock textBlock = grid.Children.OfType<TextBlock>().FirstOrDefault(); header = BindingOperations.GetBinding(textBlock, TextBlock.TextProperty).Path.Path; } catch { } } string lastHeaderName = view.SortDescriptions[0].PropertyName; string lastDirection = view.SortDescriptions[0].Direction.ToString(); if (headerClicked != null) { if (headerClicked.Role != GridViewColumnHeaderRole.Padding) { if (header != lastHeaderName) { direction = ListSortDirection.Ascending; } else { if (lastDirection == "Ascending") { direction = ListSortDirection.Descending; } else { direction = ListSortDirection.Ascending; } }

如果您將事件處理程序連接到ListViews您的 XAML 標記中，如下所示：
<ListView GridViewColumnHeader.Click="GridViewColumnHeaderClickedHandler">
...你可以簡單地提出sender論點：
void GridViewColumnHeaderClickedHandler(object sender, RoutedEventArgs e)
{
ListView listView = sender as ListView;
ICollectionView view = CollectionViewSource.GetDefaultView(listView.ItemsSource);
//...
}
