我创建了一个GridView和Contacs的DetailsView。我希望如果用户在GridView中选择一个联系人,它将在GridView中显示完整的详细信息。
这是aspx源代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Contacs.aspx.cs" Inherits="Atid4.Contacs" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID"
DataSourceID="SqlDataSourceMain"
ShowSelectButton="true"
EnableViewState="true"
EnablePersistedSelection="true"
OnSelectedIndexChanged="GridViewMain_SelectedIndexChanged">
<Columns>
<asp:CommandField ShowSelectButton="True" />
<asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="True" SortExpression="ID" />
<asp:BoundField DataField="first_name" HeaderText="first_name" SortExpression="first_name" />
<asp:BoundField DataField="last_name" HeaderText="last_name" SortExpression="last_name" />
</Columns>
</asp:GridView>
<asp:DetailsView ID="DetailsView1" runat="server" DataSourceID="SqlDataSourceMain" Height="50px" Width="125px">
</asp:DetailsView>
<asp:SqlDataSource ID="SqlDataSourceMain" runat="server" ConnectionString="<%$ ConnectionStrings:AtidConnectionString %>" SelectCommand="SELECT * FROM [Contacs]"></asp:SqlDataSource>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
我添加了一个函数GridViewMain_SelectedIndexChanged,当用户在Gridview中选择一行时调用该函数。当用户选择其中一个联系人时,会调用该函数,但联系人在GridView中不会更改。它继续显示第一个联系人。
这是背后的代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Atid4
{
public partial class Contacs : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
DetailsView1.DataBind();
}
}
protected void GridViewMain_SelectedIndexChanged(object sender, EventArgs e)
{
DetailsView1.SetPageIndex(GridView1.SelectedIndex);
}
}
}
感谢。

我在DetialsView中通过EnablePaging解决了它。
