メイン ウィンドウが最大化され、特定のタブが表示され、タブ コントロールの一番上に表示されると、しばしばハングする (完全に応答しなくなる) WPF アプリケーションがあります。ウィンドウが元に戻ると、魅力のように機能します。これを修正するにはどうすればよいですか?
問題のタブには多くのコントロール (テキストボックス、画像、ボタン、コンボボックス、グリッドスプリッター、テキストブロック、データグリッド) があり、これらのさまざまなフィールドからのイベントで点灯しているので、非常に「忙しい」グリッドです。
未解決の次の問題に似ているように聞こえます: ウィンドウが最大化されたときに WPF Datagrids がフリーズする58dc7fdf-b43c-4782-833f-1d90401f1914 )
私は本来あるべきアプリケーションを設計しておらず、メイン ウィンドウに 3000 行以上のコードが表示されていると言って締めくくりたいと思います。おそらく、これらのビジーなフォームをユーザー コントロールとして作成する必要がありました。これは私の問題を引き起こしていますか?
