Question

我正在使用GridView绑定数据库中的数据。当我执行程序时，数据将绑定在'Gridview'中，但Grid未显示。但是当我得到网格行Count时，它显示3.为什么它不显示。我在Search之前和之后使用同一网格作为商店值。在搜索之前（加载时）所有值都将是Bind，但是在Gird中没有变化之后......

代码：

 gvUserManage.DataSource = dsCandiDeat.Tables[0];
   gvUserManage.PageIndex = PageIndex;
   gvUserManage.DataBind();
   int c= gvUserManage.Rows.Count;

How to: Set Access Keys for Web Server Control

您的代码：

<asp:Label ID="lblGrdLocation" runat="server" 
           Text='<%# Eval("Location")+"  "+ Eval("JobZipCode")%>' 
           ToolTip='<%# Eval("Location")+"  "+ Eval("JobZipCode")%>' AccessKey >   
</asp:Label>

可能它没有解决问题但是这个陈述在您的标记中可能会有问题。

要为Label控件指定Access Key，您必须指定AssociatedControlID。有关详细信息，请参阅上面的MSDN参考。

此外，您必须查看gvUserManage_RowDataBound事件。
