如何循环获取radiobutton的值
- C# code
<asp:DataList ID="DataList1" runat="server" Height="241px" Width="775px"> <ItemTemplate> <table> <tr> <td> <%#Container.ItemIndex+1 %> 、<asp:Label ID="timu" runat="server" Text='<%#Eval("question") %>'></asp:Label> </td> </tr> <tr> <td> <asp:RadioButton ID="A" runat="server" GroupName="radion" />A、<asp:Label ID="Label1" runat="server" Text='<%#Eval("A") %>'></asp:Label> <asp:RadioButton ID="B" runat="server" GroupName="radion" />B、<asp:Label ID="Label2" runat="server" Text='<%#Eval("B") %>'></asp:Label> <asp:RadioButton ID="C" runat="server" GroupName="radion" />C、<asp:Label ID="Label3" runat="server" Text='<%#Eval("C") %>'></asp:Label> <asp:RadioButton ID="D" runat="server" GroupName="radion" />D、<asp:Label ID="Label4" runat="server" Text='<%#Eval("D") %>'></asp:Label> </td> </tr> </table> </ItemTemplate> </asp:DataList>[解决办法]
首先在 DataList里面加入一个页眉按钮 代码如下 ，修改按钮的CommandName为submit这个名字
<FooterTemplate>
<asp:Button ID="Button1" runat="server" CommandName="submit"
OnClick="submit_Click" Text="提交" />
</FooterTemplate>
然后在页面在 DataList 控件双击事件 ItemCommand
代码如：
- C# code
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e) { if (e.CommandName == "submit") { for (int i = 0; i <= e.Item.Controls.Count; i++)//根据你一个有多少个选项循环多少次 { RadioButton A = (RadioButton)DataList1.Items[i].FindControl("A");//第i选题第1个选项 if (A.Checked) { Label Label1 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label1"); string value = Label1.Text; } RadioButton B = (RadioButton)DataList1.Items[i].FindControl("B");//第i题第2个选项 if (A.Checked) { Label Label2 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label2"); string value = Label2.Text; } RadioButton C = (RadioButton)DataList1.Items[i].FindControl("C");//第i题第3个选项 if (A.Checked) { Label Label3 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label3"); string value = Label3.Text; } RadioButton D = (RadioButton)DataList1.Items[i].FindControl("D");//第i题第4个选项 if (A.Checked) { Label Label4 = (Label)DataList1.Items[e.Item.ItemIndex].FindControl("Label4"); string value = Label4.Text; } } }
