Question

所以我创建了一个带有下拉列表的Web表单，其中包含学校中的不同课程，如果您选择一个，您将在下面的GridView中获得所选课程的所有学生。所以我现在要做的是，如果我点击一个学生，它应该打开一个关于学生的更详细的页面，但我没有线索如何做到这一点。我得到了.mdf数据库文件的所有数据。

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="schueler.aspx.cs" Inherits="ASPXUebung.schueler" %>

Answer 1

将学生姓名列设为超链接列，如下所示：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="S_SCHNR" DataSourceID="SqlDataSource1schueler">
    <Columns>
        <asp:HyperLinkField DataNavigateUrlFields="S_SCHNR"
          DataNavigateUrlFormatString="StudentInfo.aspx?id={0}
          DataTextField="S_Name" "/>
        <asp:BoundField DataField="S_SCHNR" HeaderText="S_SCHNR" ReadOnly="True" SortExpression="S_SCHNR" />
        <asp:BoundField DataField="S_Name" HeaderText="S_Name" SortExpression="S_Name" />
        <asp:BoundField DataField="S_Vorname" HeaderText="S_Vorname" SortExpression="S_Vorname" />
        <asp:BoundField DataField="S_Gebdat" HeaderText="S_Gebdat" SortExpression="S_Gebdat" />
        <asp:BoundField DataField="S_Adresse" HeaderText="S_Adresse" SortExpression="S_Adresse" />
        <asp:BoundField DataField="S_K_Klasse" HeaderText="S_K_Klasse" SortExpression="S_K_Klasse" />
    </Columns>
</asp:GridView>

制作另一个名为StudentInfo.aspx的网页。在该页面上，使用DetailsView控件，SqlDataSource控件和QueryString参数显示数据。以下是如何执行此操作的示例：http://msdn.microsoft.com/en-us/library/xt50s8kz(v=vs.100).aspx

Answer 2

在不创建新页面的情况下，更方便的方法是将数据填充到像this这样的Bootstrap模式中。它使用UpdatePanel，它可能是您想要使用的东西，也可能不是。

将详细事件添加到Gridview。
使用FormView
从后面的C＃代码调用jQuery，使用GridView中的ID填充FormView中的数据。

gridview中每个条目的详细信息
