是这样的,我用vs.net2005实现了邦定，能显示数据．

但是我现在要实现从Gridview HyperLinkField的链接

<asp:HyperLinkField DataTextField="name"
HeaderText="姓名" SortExpression="id" Target="_blank" DataNavigateUrlFormatString="showdetails.aspx?id={0}" DataNavigateUrlFields="id" />

有什么问题？

[QQMagicer]

<asp:HyperLinkField DataTextField="name"
HeaderText="姓名" SortExpression="id" Target="_blank" DataNavigateUrlFormatString="showdetails.aspx?id={0}" DataNavigateUrlFields="<%Eval("id")%>" /> //这里绑定一下

在datalist 的页面怎么用 Request.QueryString 接收hyperlinkfield的值,

我这样写报错

if(!this.IsPostBack)
{
string id=Request.QueryString["id"].ToString();
String strConnection=ConfigurationSettings.AppSettings["ConnectionString"];
SqlConnection myConnection=new SqlConnection(strConnection);
myConnection.Open();
SqlCommand cmd=new SqlCommand("select name from login",myConnection);
this.Label1.Text=Convert.ToString(cmd.ExecuteScalar());
cmd.CommandText="select * from login";
SqlDataReader sdr=cmd.ExecuteReader();
this.DataList1.DataSour

报以下错误

行 26: SqlCommand cmd=new SqlCommand("select name from login where id=+'"+id+"'",myConnection);

改成这样

SqlCommand cmd=new SqlCommand("select name from login where id=+'"+Request.QueryString["id"]+"'",myConnection);

或者也可以把这样把id定义为全局变量，并把
id=Request.QueryString["id"].ToString();
拿到
if(!this.IsPostBack)
的上面。

代码：

string id;

protected void Page_Load(object sender, EventArgs e)
{
id=Request.QueryString["id"].ToString();

if(!this.IsPostBack)
{

String strConnection=ConfigurationSettings.AppSettings["ConnectionString"];
SqlConnection myConnection=new SqlConnection(strConnection);
myConnection.Open();
SqlCommand cmd=new SqlCommand("select name from login",myConnection);
this.Label1.Text=Convert.ToString(cmd.ExecuteScalar());
cmd.CommandText="select * from login";
SqlDataReader sdr=cmd.ExecuteReader();
this.DataList1.DataSour
