私の問題は、ListBox と ItemContainerStyle の両方のスタイルを持つリストボックスを持つ 3 つのタブ コントロールがあり、タブ内のすべてのリストボックスでスタイルが同じであることです。
2 つのタブは、CollectionViewSource を使用してデータバインドされています。
問題は、タブ2に入ろうとするとすぐに例外が発生し、どこから来たのかわからないようです（最初のチャンスの例外を有効にするのにも疲れましたが、何もありません）
それをいじってみると、タブ 2 の ListBox から ItemContainerStyle を削除すると、クラッシュしなくなることがわかりました。クラッシュを防ぐ別の方法は、リストボックスにアイテムを入れないことです。別の方法は、 CollectionViewSource を使用する代わりに、リストで GetDefaultView() を使用してそれにバインドすることです。
リストボックスにバインドするために使用する行は次のとおりです。
this.FListViewSource = (this.FindResource("FirstCollectionViewSource") as AutoRefreshCollectionViewSource);
this.FListViewSource.Source = this.FirstList;
this.FListView = (this.FListViewSource.View as ListCollectionView);
this.SListViewSource = (this.FindResource("SecondCollectionViewSource") as AutoRefreshCollectionViewSource);
this.SListViewSource.Source = testing;
this.SListView = (this.SListViewSource.View as ListCollectionView);
これは、タブ コントロールの XAML です。
