                        </td>
              </tr>
         </table>

</asp:Panel>

这是我的服务器代码

Here is my Server Code

protected void ddl_mode_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (ddl_mode.SelectedIndex == 0)
        {
            Pnl_pay_Cheque.Visible = false;
            Pnl_pay_Card.Visible = false;
            txt_enteramt.Text = "0";

        }
        else if (ddl_mode.SelectedIndex == 1)
        {
            Pnl_pay_Cheque.Visible = true;
            Pnl_pay_Card.Visible = false;
            txt_enteramt.Text = "0";

        }
        else if (ddl_mode.SelectedIndex == 2)
        {
            Pnl_pay_Card.Visible = true;
            Pnl_pay_Cheque.Visible = false;
            txt_enteramt.Text = "0";
        }
        txt_enteramt.Text = "";
    }

实际上，当用户更改DropDownlist项目时，我需要隐藏/显示相应的面板.

Actually while user Changing the DropDownlist items, i need to hide/Show the respective Panels.

推荐答案

亲爱的，正如我在代码中看到的那样，看来您正在放置面板在更新面板控件之外
在这种情况下，您将无法在更新面板之外更新/刷新控件.

尝试将面板放在< contenttemplate>之间.并且它将正常工作.

我已经准备好解决任何问题，如果您想通过电子邮件发送我的邮件以快速回答问题，您可以直接与我联系


谢谢.

Dear as i can see in the code it seems your are putting the panel outside the update Panel control
in this case you can''t update/refresh the controls outside the update panel.

try to put the panels between the <contenttemplate> and and it will work fine.

i''m ready for any question and u can communicate with me directly if you want put your email to send mine for fast answer


Thank you.

能否请您解释一下，您能输入您正在使用的aspx代码吗?
