多个RadioButtonList在结束时如何查看那个未选
如题~~恩有后台的给后台~~前台的麻烦说详细点~~- -
------解决方案--------------------代码都贴给你了,基础要加强啊,如果直接复制都搞不出来。。。
前台:
<body>
<form id="form1" runat="server">
<div>
<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True">
<asp:ListItem>AAA</asp:ListItem>
<asp:ListItem>BBB</asp:ListItem>
<asp:ListItem>CCC</asp:ListItem>
</asp:RadioButtonList> </div>
<br />
<asp:RadioButtonList ID="RadioButtonList2" runat="server" AutoPostBack="True">
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
<asp:ListItem>3</asp:ListItem>
</asp:RadioButtonList>
</form>
</body>
后台:
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
foreach (Control cl in form1.Controls)
{
if (cl is RadioButtonList)
{
if (((RadioButtonList)cl).SelectedIndex == -1)
{
Response.Write(cl.ID + "未选择<br>");
