asp.net中求GridView与DetailView的结合使用方法
asp.net中GridView与DetailView都要是后台绑定数据，且是用带参存储过程去绑定数据的。实现主从表的效果，gridview只显示ID，名称和类别，当选中某行时detailview显示该行的详细信息，求大神帮忙 asp.net gridview 数据 存储 detailview

何必用DetailView呢，直接在TemplateField显示详细信息不就行了，例如

<asp:GridView runat="server" ID="gv" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="EmployeeID" HeaderText="ID" />
        <asp:TemplateField HeaderText="个人信息">
            <ItemTemplate>
                <p>名：<%# Eval("FirstName") %></p>
                <p>姓：<%# Eval("LastName") %></p>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

楼主说的应该是Gridview里只显示2、3列，然后DetailView才显示整张表的内容吧

恩，确实是我理解错了，重新写了demo，比较粗糙，楼主借鉴下

<asp:GridView runat="server" ID="gv" AutoGenerateColumns="false" 
    OnRowCommand="OnSelected" DataKeyNames="EmployeeID">
    <Columns>
        <asp:ButtonField ButtonType="Button" CommandName="select" Text="select" />
        <asp:BoundField DataField="EmployeeID" />
        <asp:BoundField DataField="LastName" />
    </Columns>
</asp:GridView>
<br />
<asp:DetailsView runat="server" ID="dv">
</asp:DetailsView>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        string strConn = WebConfigurationManager.ConnectionStrings["Northwind"].ToString();
        SqlConnection conn = new SqlConnection(strConn);

        SqlCommand comm = new SqlCommand();
        comm.Connection = conn;
        comm.CommandText = "select * from Employees";

        DataTable dt = new DataTable();
        try
        {
            conn.Open();

            SqlDataReader reader = comm.ExecuteReader();
            dt.Load(reader);

            gv.DataSource = dt;
            gv.DataBind();

            reader.Close();
        }
        finally
        {
            conn.Close();
        }
    }
}

protected void OnSelected(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "select")
    {
        int i = int.Parse(e.CommandArgument.ToString());
        string strID = gv.DataKeys[i].Value.ToString();

        string strConn = WebConfigurationManager.ConnectionStrings["Northwind"].ToString();
        SqlConnection conn = new SqlConnection(strConn);

        SqlCommand comm = new SqlCommand();
        comm.Connection = conn; 
 
        comm.CommandText = "select * from Employees where EmployeeID=" + strID;

        DataTable dt = new DataTable();
        try
        {
            conn.Open();

            SqlDataReader reader = comm.ExecuteReader();
            dt.Load(reader);

            dv.DataSource = dt;
            dv.DataBind();

            reader.Close();
        }
        finally
        {
            conn.Close();
        }
    }
}
