在Telerik RadGrid中,用戶可以添加一行並編輯現有的行。看起來,網格實際上強制在UI控件呈現在屏幕上之前發生回傳。我注意到從點擊按鈕到控件出現的時間延遲了二到二秒。這似乎大約是一秒到兩秒太長。這裏是我的代碼,我不完全確定這個bug是什麼。Telerik RadGrid添加/編輯行性能問題
我很抱歉提前「whatz wrongz與我codez post」,但這似乎是最簡單的方法去了解這一個。同樣,我有一個性能問題,並想弄清楚如何解決它在什麼的需要進行調整代碼方面.....

我需要查看。我相信功能是空的。 – RSolberg 2009-12-17 15:58:36
謝謝!它實際上似乎可能有一些代碼在回發的Page_Load函數內運行,而不應該。我稍後會給這個測試看看它是如何執行的。我還刪除了諸如NeedDataSource的特定事件,因爲那裏沒有代碼。這是從另一個應用程序複製/粘貼實施:) – RSolberg 2009-12-17 19:57:05
