我完全是asp.net中的新特性,我遇到了一些問題。 我爲演示和學習創建了litle web表單,我遇到了一些問題。 Hopefuly你能幫助我:)Asp.net中事件的問題
我想要的是:
- 當我點擊表格中的「殺X」按鈕,我得到了標籤「lblMsg」「你按下按鈕,殺死X」消息。我也希望我有新的數據表。
- 當我點擊「加載」按鈕,我需要在表中獲得額外的行。例如,現在當頁面加載時,表中有10行,當我單擊「加載」時,我需要將最後10行添加到同一個表中。
P.S.: 我將不勝感激一些教程如何處理在asp.net中的事件。

謝謝你的例子和建議。但我仍然想知道如何對我當前的代碼進行覈實,這些代碼將按照需要工作。 – Primoz 2010-11-04 13:04:18
