                                <br />
                                <br />

                                <br />
                                <br />
                                <asp:Label ID="lbpid9" runat="server" Text='<%# Eval("pid") %>' Visible="False">
                            
                        </td>
                    </tr>
                    <tr>
                        <td style="width: 413px; height: 69px;">
                            <asp:Label ID="lbulocation1" runat="server" Text='<%# Eval("ulocation") %>'>
                        </td>
                    </tr>
                </table>
                <br />
            </itemtemplate>
            <SelectedItemStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />

这是逻辑代码：

and this is logical code :

protected void lbpname4_Click(object sender, EventArgs e)
   {
       SqlCommand cmd = new SqlCommand("Select * from AddPost", con);
       con.Open();
       SqlDataReader dr = cmd.ExecuteReader();
       while (dr.Read())
       {

               Session["pname"] = dr["pname"];
               Response.Redirect("Cate.aspx");
       }
       con.Close();
   }

推荐答案

所以，基本上你是从 DataReader 总是如此。你需要改变你的逻辑。

So, basically you are reading the first row value from the DataReader always. You need to change your logic.
