radiobuttonList的做法

js验证：

var sex = document.getElementsByName("rbl_sex");

var flag = true;
for (var i = 1; i < sex.length; i++) {
if (sex[i].checked == true) {
flag = false;
}
}
if (flag) {
alert("请选择性别！");
return false;
}

页面操作：

<asp:RadioButtonList ID="rbl_sex" runat="server" RepeatDirection="Horizontal">
<asp:ListItem Text="男" Value="0" />
<asp:ListItem Text="女" Value="1" />
</asp:RadioButtonList>

后台赋值：

if (LeagueCarOwer.性别 == "男")
{
rbl_sex.SelectedValue = "0";
}
else
{
rbl_sex.SelectedValue = "1";
}

插入数据库：

LeagueCarOwer.Dat_性别 = Convert.ToDecimal(rbl_sex.SelectedValue);

checkbox选中：
car.加盟邀请=0;
if (ckb_carYQEnable.Checked)
{
car.加盟邀请 = 0;
}
else
{
car.加盟邀请 = 1;
}
