Hi guys are working on this project for school and have a problem

        

    <asp:LinkButton ID="LinkEdit" runat="server" CssClass="right_bottom" 
        onclick="LinkEdit_Click" Height="16px">edit</asp:LinkButton>
    <asp:LinkButton ID="Linkhide" runat="server" CssClass="right_bottom" 
        onclick="Linkhide_Click" Visible="False" hide</asp:LinkButton>
    <br />
    <hr style="width: 740px; height: -6px; margin-left: 0px; " />
    <asp:Label ID="labelFullname" runat="server" Text="Full Name" CssClass="left_top"></asp:Label>
    <asp:Label ID="labelNameDisplay" runat="server" Text="Put name here" CssClass="right_top"></asp:Label>

    <br />
    <asp:Panel ID="panelName" runat="server" Height="240px" Visible="False" CssClass="panel_top"
        style="text-align: left;">

        <asp:Label ID="Label8" runat="server" CssClass="left" Text="Please allow 24 hours for name changes to take effect."></asp:Label>
    <div align="center"><br />
    <br />
    <table>
       <tr>
       <td class="label_new">
         <asp:Label ID="Label4" runat="server" Text="Full Name:" ToolTip="Name Displayed"></asp:Label>
         </td>
         <td align="left">

          <asp:DropDownList ID="DropDownList1"  runat="server" BorderStyle="Groove" 
                 Font-Names="Segoe UI,Tahoma,Verdana,Arial,Times" Font-Size="100%" Height="25px" 
          valign="middle" Width="250px">
              <asp:ListItem></asp:ListItem>
              <asp:ListItem></asp:ListItem>
              <asp:ListItem></asp:ListItem>
          </asp:DropDownList>
       </td>
  </tr>


   <tr>
       <td class="label_new">
         <asp:Label ID="Label2" runat="server" Text="First Name:"></asp:Label>
         </td>
         <td align="left">
         <asp:TextBox ID="txtFirstName" runat="server" BorderStyle="Groove" Font-Names="Segoe UI,Tahoma,Verdana,Arial,Times" Font-Size="100%" Height="20px" 
          valign="middle" Width="242px"></asp:TextBox>
       </td>
  </tr>

     <tr>
       <td class="label_new">
         <asp:Label ID="Label9" runat="server" Text="Middle Name:"></asp:Label>
         </td>
         <td align="left">
         <asp:TextBox ID="txtMiddleName" runat="server" BorderStyle="Groove" Font-Names="Segoe UI,Tahoma,Verdana,Arial,Times" Font-Size="100%" Height="20px" 
          valign="middle" Width="242px" onfocus="if (this.value == 'optional') {   this.value='';  this.style.color='black';}" />
       </td>
  </tr>

     <tr>
       <td class="label_new">
         <asp:Label ID="Label10" runat="server" Text="Last Name:"></asp:Label>
         </td>
         <td align="left">
         <asp:TextBox ID="txtLastName" runat="server" BorderStyle="Groove" Font-Names="Segoe UI,Tahoma,Verdana,Arial,Times" Font-Size="100%" Height="20px" 
          valign="middle" Width="242px"></asp:TextBox>
       </td>
  </tr>
  <tr>
  <td colspan="2">
      <asp:Button ID="btnSaveChanges" runat="server" Text="Save Changes" 
          onclick="btnSaveChanges_Click" />
  </td>
  </tr>
    </table>
    </div>

    </asp:Panel>

我有4个小组以这种形式就像在Facebook帐户设置。
我在这里的问题是，当我告诉它只是跳转到页面顶部的面板。

I have 4 panels in this format just like ACCOUNT SETTINGS on facebook. My problem here is when i show the panel it just jump to the top of the page.

会喜欢这样做只是为Facebook的方式是。点击并在ü点击在同一个位置上。

Will like to do it just as the way facebook is. click and be on at the same position of where u clicked.

感谢

推荐答案

您可以设置MaintainScrollPositionOnPostback属性页面上：

You can set the MaintainScrollPositionOnPostback property on your page:

Page.MaintainScrollPositionOnPostback = true;

，或把它放在网页声明

or put it in the page declaration

<%@ Page MaintainScrollPositionOnPostback="true" %>
