GridView上的編輯按鈕沒有用輸入框數據更新

Question

我知道這是非常基本的，幾乎如此基本，很難找到相關的例子。

我有一個gridview表查詢數據庫，並使用VS17我想添加一個編輯列。我使用設計器佈局生成了以下代碼，但是當我單擊編輯按鈕時，該行變爲可編輯，但更新語句不更新數據庫。一旦我點擊更新，頁面刷新並且表格消失。

我哪裏錯了？另外，我知道前任在列名中使用的拼寫錯誤。

這裏的CS文件：

<br />

非常基本的，我知道，但這不是我的強項，我好像不能找到一個適用的例子或少量文件。任何幫助，將不勝感激！

您可能需要將以下屬性添加到您的網格視圖中，然後在您的代碼中實現它們。如果你使用VS17，它會幫助你做到這一點。在網格視圖內部，首先輸入OnRowEditing,OnRowUpdating。這應該讓你開始。您可能也想要實施OnRowCancelingEdit方法。
