问题描述
大家晚上好...............
我有一个包含5或6个项目的下拉列表，一个复选框列表填充在dropdownlist值上.
我的.aspx页面代码如下..
good evening to all..............
I have one dropdownlist with 5 or 6 item and one checkboxlist populate on dropdownlist value.
my .aspx page code is given below..
<asp:DropDownList ID="ddlstDesignation" AutoPostBack="true" runat="server" Width="193px" onselectedindexchanged="ddlstDesignation_SelectedIndexChanged" Height="25px"> <asp:ListItem Value="--Select--">--Select--</asp:ListItem> <asp:ListItem Value="1">National Sales Manager</asp:ListItem> <asp:ListItem Value="2">Region Manager</asp:ListItem> <asp:ListItem Value="3">Branch Manager</asp:ListItem> <asp:ListItem Value="4">Area Manager</asp:ListItem> <asp:ListItem Value="5">Supervisor</asp:ListItem>
<asp:ListItem Value="6">Salesman</asp:ListItem> </asp:DropDownList>
<cc1:CheckBoxListExCtrl ID="CheckBoxListExCtrl1" RepeatDirection="Horizontal" RepeatColumns="2" runat="server"> </cc1:CheckBoxListExCtrl>
在选择dropdownlist值时，复选框列表会填充其工作良好....但是当我每次提交页面时都选择dropdownlist值时...
我需要针对此selectedindexchange的JavaScript....
我在.aspx.cs文件后面的代码在下面给出

i need javascript for this selectedindexchange....
my code behind .aspx.cs file are given below

推荐答案
我相信您想与页面进行交互，而无需正确地回发刷新页面?
使用更新面板 [ http://msdn.microsoft.com/en-us/magazine /cc163363.aspx [ ^ ]尽管我建议使用 jQuery [ ^ ]
I believe you want to interact with the page without postback refreshing hte page correct?
You can accomplish this easly, and without JavaScript, using Update Panel[^]
With JavaScript you will need to use AJAX, http://msdn.microsoft.com/en-us/magazine/cc163363.aspx[^] though I would suggest using Jquery[^]
