May be you may think why am I using link buttons as we are provided with some command field buttons by Grid View.

So Grid View will put the appropriate row into the Edit Mode by assigning row number to its Edit Index property. You can follow any responses to this entry through the RSS 2.0 feed.

Then again we have to call that Bind Grid Data () method to bind data for the textboxes. You can leave a response, or trackback from your own site.

If we move our mouse on to the variables, which hold the cell values, we can see the old value instead of new updated value (Refer the debugging Screen Shot at the Top).

There are similar questions on Stackoverflow and other websites, but I seem to miss something.

From this article, you will have a clear view of the Grid View data insert, delete, and update operations.

Make two tables in a database: Contact and Contact Type.By default all the boundfields will be trasferred as Textboxes in Edit Mode.To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.拉一個 Grid View,將 Data Source ID 設定為 Sql Data Source 的 ID 完畢!Grid View的入門就這樣子而已,一整個讓人懷疑到底有沒有學了東西,內容量實在少到無言,不過的確是可以執行的。 如果還需要其它的功能,只要有碰過 Grid View 的人就知道,只要在屬性的地方,滑鼠東點點、西選選,分頁之類的功能全部配備完成。 但是,如果不依靠 Sql Data Source 的話呢?全部用程式碼處理的話呢?我覺得這是個很美妙的事情就是了。 嘛,不是說 Sql Data Source 不好,只是自從會用程式碼做事情之後,就不喜歡它了,就這點來說,或許我有一些喜新厭舊的壞習性?! 就不曉得使用 Sql Data Source 跟 Code Behind 兩種方法,哪一種效能比較好就是了(皺眉)。 以下依序講 Grid View 的功能:利用程式碼塞 Grid View 資料、分頁功能、編輯功能、刪除功能 其中要注意的昰:當 Grid View 沒有指定 Data Source ID 時,是不會執行-ed事件,只執行-ing事件 1. Set Gridview() :這一個 function 可是很重要的!把它單獨寫出來至少就方便一半了,因為之後隨時要呼叫它 3. 編輯功能:雖然這看起來只是一個功能,但我們必須要分幾個步驟來看。 Step 1:按下「編輯」按鈕 Step 2:編輯完成後,按下「更新」按鈕;或者按下「取消」按鈕 從上述文字中不難發現,編輯這個作業流程中,至少會有三種事件會發生: Event 1 :按下「編輯」按鈕,Grid View 進入編輯模式 Event 2 :按下「更新」按鈕,更新資料、Grid View 離開編輯模式 Event 3 :按下「取消」按鈕,單純讓 Grid View 離開編輯模式 因此,對於此編輯功能,會需要寫三個事件: Event 1 :按下「編輯」按鈕,Grid View 進入編輯模式 在這裡唯一沒提到的就是新增資料的功能,目前網路上找我也沒找到就是了,而且在 Grid View 的事件中,也沒有看到什麼 Gridview_Row Inserting 之類的東西,所以都是另外拉 Text Box 、 Button 之類的,另外處理 insert ,只是話說回來,我覺得這樣做也沒有什麼不好啦,不然一排新增的按鈕……感覺很多餘就是了。 最後,做個總結: 要注意的事項有: 1. 沒有使用 Sql Data Source,而 Grid View 在沒有指定 Data Source ID 時,是不會執行-ed事件,只執行-ing事件 3. I had a assignment I need to show only description and not ID. By using Datakeynames property you will get the selected row primary key.
