问题描述

我有一个网页表单，上面有一个网格视图。网格查看器只显示我选择显示的几列。当我想在网格视图中更新一列时，单击左侧的编辑链接，这些字段将打开以进行编辑。然后我将一个列数据从True更改为False。然后我点击左侧的更新链接，所有数字数据都消失了，但不是我改变了。为什么会这样？我做错了什么？它适用于我的其他项目，但这不是。



这是我的Gridview代码：



I have a web form that has a Grid view on it. The Grid viewer shows just a couple of columns I chose to show. When I want to update one column in the Grid view I click on the Edit link to the left and the fields are open to be edited. Then I change one column data from True to False. I then click on the Update link to the left and all of the number data is gone but not what I changed. Why does this happen? What did I do wrong? It works on my other projects but this one it is not.

Here is my Gridview code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
