在gridview中绑定单选按钮 [英] Binding Radio buttons in gridview

问题描述

嗨专家。



我在gridview中绑定单选按钮时遇到问题。我正在做一个项目在线测试。每个问题都有4/5单选按钮。在这里我写的示例代码

< asp：DataList ID =   dalsurvey runat =   server >  
< ItemTemplate> 
< table> 
< tr> 
< td> 
< span style =   font-size：14px; font-weight：bold;<％＃Eval（ 答案）％ >  < /   span  >  
 < /   td   >  
 < /   tr  >  
< tr> 
< td> 
<输入名称=   MyRadioButton  class  =   radioButton type =    radio id = ' <％ #Eval（Description）％>'  value  = ' <％＃Eval（Description）％>'<％＃Convert.ToString（Eval（ < span class =code-string> Description））！=  ？  ：  hidden ％>  /> 
< asp：Label ID =   Label2 runat =   server Text = ' <％＃Eval（说明）％>' >  < /   asp：标签 >  
  < /   td  >  
 < /   tr  >  
 < /  表格 >  
 
< /   ItemTemplate  >  
 < /   asp：DataList  >  

这里我应该只能选择一个。但我想在每个问题中选择一个单选按钮..我该怎么做...？

解决方案

在网格视图中添加Redio按钮你必须添加templatefield

如下：

 <   asp：GridView     ID  < span class =code-keyword> =  GridView1    runat   =  server >  
 <  列 >  
 <   asp：BoundField     DataF ield   =  PID    HeaderText   =  PID    ReadOnly   =  True    SortExpression   =   ProductID    /  < span class =code-keyword>>  
 <   asp：BoundField     DataField   =  ProductName    HeaderText   =  ProductName    SortExpression   =  PName    /  >  
 <   asp：BoundField     DataField   = 价格    HeaderText   = 价格    SortExpression   = 价格    /  >  
 <  < span class =code-leadattribute> asp：TemplateField     HeaderText   = 选择一个 >  
 <   ItemTemplate  >  
 < span class =code-keyword><   input     name   =  RadioButton    type   =  radio    value   ='  <％ #Eval（   value）％> '    /  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 <   /列 >  
 <   /     asp：GridView    >

                      <ItemTemplate>
                          <table>
                              <tr>

                                          <input name="MyRadioButton" class="radioButton" type="radio" id='<%# Eval("Description") %>' value='<%# Eval("Description") %>'  <%# Convert.ToString(Eval("Description")) != "" ? "" : "hidden"  %>  />
                                           <asp:Label ID="Label2" runat="server" Text='<%#Eval("Description") %>'></asp:Label>
                                  </td>
                              </tr>
                          </table>
                      
                           </ItemTemplate>
                  </asp:DataList>

here i should be able to select only one. but i want to select in each question one radio button.. how can i do this...?

解决方案

to add Redio button inside grid view you have to add templatefield
as given below :

<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:BoundField DataField="PID" HeaderText="PID" ReadOnly="True" SortExpression="ProductID" />
<asp:BoundField DataField="ProductName" HeaderText="ProductName" SortExpression="PName" />
<asp:BoundField DataField="Price" HeaderText="Price" SortExpression="Price" />
<asp:TemplateField HeaderText="Select One">
<ItemTemplate>
<input name="RadioButton" type="radio" value='<%# Eval("value") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</ asp:GridView >
