但却无法完成更新（点击更新时，字段无变化）是什么原因？？？ --------------------编程问答-------------------- 自己先顶个
没人回答吗？？？
急急急急急急急急急急急急急急急急急急急急急急急急急急急急急 --------------------编程问答-------------------- 我认为是因为你把每列都换成了模板列的缘故.把自己搞麻烦了,结果反而出问题.
你不用换成模板列,可以直接改列标题,再把DataField属性写成你要帮的字段就行了. --------------------编程问答-------------------- 1。
GridView中更新时难道必须自己添加代码？
－－－－－－－－－－－
你直接使用 xxxDataSource 是不需要自己另外写代码的
2。
xxxDataSource 问题，我无法解释了，基本没用过 :D
按理，对于 xxxDataSource 来说，不应该存在 IsPostBack 的问题 --------------------编程问答-------------------- 3。
哦， 看到问题所在了， 好像是因为你没有指定主键
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" CellPadding="4" ForeColor="#333333" GridLines="None" Width="630px">
》》》 加上 DataKeyNames，这里假设你的主键是 Customer_ID
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" CellPadding="4" ForeColor="#333333" GridLines="None" Width="630px" DataKeyNames="Customer_ID"> --------------------编程问答-------------------- 更新之后要重新以下绑定一下DataView才行 --------------------编程问答-------------------- 还是建议不要用这个功能吧。 呵呵呵呵 --------------------编程问答-------------------- 更新后,要重新刷新下GridView,这样的话,你的数据就是比较新的数据.我经常使用这个.
不明白可以联系:MSN:wzhh598@hotmail.com --------------------编程问答-------------------- 是主键问题。 --------------------编程问答-------------------- 修改数据以后，刷新一下dataview --------------------编程问答-------------------- 让人很不解的是
怎么会有两个id= label1
一定有问题 --------------------编程问答-------------------- 路过··· --------------------编程问答-------------------- 更新后要重新绑定一下....
