问题描述

我有一个RadioButtonList控件。

如何更改列表中只有一个raido按钮的选择？在选择上述以外的单选按钮时，不应发生任何变化。



我只想在下面的代码中检查最后一个单选按钮（无津贴）时进行更改。

 <   asp：RadioButtonList     ID   =  RadioButtonList1     runat   = < span class =code-keyword> server    
   
              < span class =code-attribute>                          < span class =code-attribute>           RepeatDirection   = 水平 >  
 <   asp：ListItem  > 已修复<   / asp：ListItem  >  
 <   asp：ListItem  > 变量<   / asp： ListItem  >  
 <   asp：ListItem  > 费用涵盖<   / asp：ListItem  >  
 <   asp：ListItem    > 无津贴<   / asp：ListItem  >  
 < SP class =code-keyword><   / asp：RadioButtonList  >  

解决方案

更改此类代码

 <   asp：RadioButtonList     ID   =  RadioButtonList1    AutoPostBack   =  true    runat   =  server  
    < span class =code-attribute>            < span class =code-attribute>                                 RepeatDirection   =  水平    OnSelectedIndexChanged  < span class =code-keyword> =  RadioButtonList1_SelectedIndexChanged >  
 <   asp：ListItem  > 已修复<   / asp：ListItem  >  
 <   asp：ListItem  > 变量<   / asp：ListItem  >  
 <   asp：ListItem  > 费用涵盖< ;   / asp：ListItem  >  
 <   asp：ListItem    >  No Stipend <   / asp：ListItem  < span class =code-keyword>>  
 <   / asp：RadioButtonList  >  
 

$ c $ b在cs页面添加以下



<前lang =cs> 受保护 void RadioButtonList1_SelectedIndexChanged（ object sender，EventArgs e）
{
if （RadioButtonList1.SelectedItem.Text == No Stipend）
{
// 您的代码
}
}

使用OnSelectedIndexChanged < a href =http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listcontrol.selectedindexchanged(v=vs.110).aspx>活动 [ ^ ]



在这种情况下，您可以检查所选项目是否无津贴是否有文本或数据库中的值。



如果你能做的话

 RadioButtonList rdbl =（RadioButtonList）sender; 
  var  selectedValue = rdbl.SelectedItem.Value; 
  var  selectedText = rdbl.SelectedItem.Text; 

I have one RadioButtonList control.
How to make changes on selection of just one raido button of the list ? While selection of radio button other than this mentioned above, no change should occur.

I want to make change only when last radio button(No stipend) from below code is checked.

<asp:RadioButtonList ID="RadioButtonList1" runat="server" 

                        RepeatDirection="Horizontal">
                        <asp:ListItem>Fixed</asp:ListItem>
                        <asp:ListItem>Variable</asp:ListItem>
                        <asp:ListItem>Expenses Covered</asp:ListItem>
                        <asp:ListItem >No Stipend</asp:ListItem>
                    </asp:RadioButtonList>

解决方案

change code like this

<asp:RadioButtonList ID="RadioButtonList1" AutoPostBack="true" runat="server"
                       RepeatDirection="Horizontal" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
                       <asp:ListItem>Fixed</asp:ListItem>
                       <asp:ListItem>Variable</asp:ListItem>
                       <asp:ListItem>Expenses Covered</asp:ListItem>
                       <asp:ListItem >No Stipend</asp:ListItem>
                   </asp:RadioButtonList>

in cs page add following

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (RadioButtonList1.SelectedItem.Text == "No Stipend")
        {
            //your code
        }
    }

Use the OnSelectedIndexChanged event[^]

In that event you can check if the selected item ha No Stipend has text or the value from the database.

In the event you can do

RadioButtonList rdbl = (RadioButtonList)sender;
var selectedValue = rdbl.SelectedItem.Value;
var selectedText = rdbl.SelectedItem.Text;
