我目前在我的項目中使用Prism WinRT。佈局週期檢測到的錯誤Windows 8.1 Gridview
基於網絡搜索這是我曾嘗試：
-
從數據模板
- 刪除進度條，（這應該已經被固定在Win 8.1雖然）
- 加入固定的寬度和高度圖像
我發現進度欄有這個錯誤，我從我的數據模板中刪除它，但我仍然看到了錯誤。
在初始加載一切似乎很好，但是當我更改視圖模型中的數據收集基於用戶選擇的過濾器，並開始滾動我間歇性地打這個問題。在讓用戶滾動之前，是否有任何事件我應該等待？
如果我使用一個堆棧面板作爲ItemsPanel，那麼我不會看到這個錯誤，但是後來我放棄了虛擬化功能，並且它永遠需要顯示大型數據集。
我已經在應用程序中提供了代碼，我可以簡化它，如果任何人想要。
