为什么程序无法检测是否选择了该选项？ [英] Why the program cant detect if the option is selected?

问题描述

我有2个文件，file.aspx和file.aspx.cs.在.aspx我有

 <   asp：RadioButtonList     ID   = < span class =code-keyword> inputOKToEmailDispatchService    runat   =  server >  
 <   asp：ListItem    值  = 是   文字  = 是 >  <   / asp：ListItem  >  
 <   asp：ListItem    值  = 无   文字  = 否 > ;  <   / asp：ListItem  > ;  
 <   / asp：RadioButtonList  >  
 

和aspx.cs我有

  string  selectedValue = inputOKToEmailDispatchService.SelectedItem.Text; 

或

  string  selectedValueSomething = inputOKToEmailDispatchService.SelectedValue.ToString（）; 

其中是问题？如果选择（检查）radiobuttonlist中的任何项目，则代码不会检测到。

谢谢：）

解决方案

所以，你已经创建了一个名为 inputOKToEmailDispatchService 的控件，在postpack上，未设置 inputOKToEmailSupplier 。不知道为什么？

我的解决方案是：



file.aspx

 <   tr  >  
 <   td    < span class =code-attribute> width   =  25％    align   =  right    valign   =  middle > 联系供应商：<   / td  >  
 <   td     width   =  75％    align   =  left     valign   = < span class =code-keyword> middle >  
 <   asp：radiobutton     id   =  inputOKToEmailSupplierYes    runat   =  server    groupname   =  inputOKToEmailSupplier    text   = 是   已选中  =  true    xmlns：asp   = ＃unknown >  <   / asp：radiobutton  >  
 <   asp：radiobutton     id   =  inputOKToEmailSupplierNo    runat   = 服务器    groupname   =  inputOKToEmailSupplier    text   = 无    xmlns：asp   = ＃unknown >  <   / asp：radiobutton  >  
 <   label     visible   =  false    id   =  suppWar    style   =  color：red    runat   = 服务器 >  <   / label  >  
 <   / td  >  
 <   / tr  >  

和file.aspx.cs

   #region OKToEmailSupplier 
   if （inputOKToEmailSupplierYes.Checked）
 {
 ContactSupplier =  1 ; 
} 
  else   if （inputOKToEmailSupplierNo.Checked）
 {
 ContactSupplier =  0 ; 
} 
   #endregion 
  

在Page_Load中，我调用了

 setFieldsToDefault（）; 

，其中我将所有属性设置为null值。我认为这是问题所在： ）

Hi, i have 2 files, file.aspx and file.aspx.cs. In .aspx i have

<asp:RadioButtonList ID="inputOKToEmailDispatchService" runat="server">
    <asp:ListItem Value="Yes" Text="Yes"></asp:ListItem>
    <asp:ListItem Value="No" Text="No"></asp:ListItem>
</asp:RadioButtonList>

and in aspx.cs i have

string selectedValue = inputOKToEmailDispatchService.SelectedItem.Text;

or

string selectedValueSomething = inputOKToEmailDispatchService.SelectedValue.ToString();

Where is the problem? The code dont detect, if the any item in radiobuttonlist is selected (checked).
Thanks :)

解决方案

So, you've created a control called inputOKToEmailDispatchService and on postpack, the inputOKToEmailSupplier is not set. Wonder why?

My solution is:

file.aspx

<tr>
                    <td width="25%" align="right" valign="middle">Contact supplier:</td>
                    <td width="75%" align="left" valign="middle">
                        <asp:radiobutton id="inputOKToEmailSupplierYes" runat="server" groupname="inputOKToEmailSupplier" text="Yes" checked="true" xmlns:asp="#unknown"></asp:radiobutton>  
						<asp:radiobutton id="inputOKToEmailSupplierNo" runat="server" groupname="inputOKToEmailSupplier" text="No" xmlns:asp="#unknown"></asp:radiobutton>
                        <label visible="false" id="suppWar" style="color:red" runat="server"></label>
                    </td>
                  </tr>

and file.aspx.cs

#region OKToEmailSupplier
if (inputOKToEmailSupplierYes.Checked)
{
    ContactSupplier = 1;
}
else if(inputOKToEmailSupplierNo.Checked)
{
    ContactSupplier = 0;
}
#endregion

In Page_Load i called the

setFieldsToDefault();

, where i put all attributes to "null" value.. I think that was the problem :)
