<td>
    <asp:LinkButton ID="LinkButton1" runat="server" CommandArgument='<%#Eval("教师号")%>'  OnCommand="LinkButton1_Command"></asp:LinkButton>
</td>

public void LinkButton1_Command(object sender,CommandEventArgs e)

     //获取CommandArgument值
     string tid = e.CommandArguments.ToString();
     Response.Redirect("jiaoshixinxishanchu1.aspx?ID="+tid);
}
