我以单一形式使用Dropdownlist，Radiobutton，Textbox和Radio Buttons。我使用了RequiredIf个验证器。当我提交表单时，验证器可以工作，但dropdowmlist和单选按钮状态将会改变。我需要在提交后不要更改选定的值。如何执行此操作我的代码是。

提交后，您可以使用ViewData传递数据y并进入“查看”以显示所选值：
<强>控制器
ViewData["Pay_mode] = Pay_mode;
查看
<script type="text/javascript">
$(document).ready(function () { var pay_mode = '@ViewData["Pay_mode"]';
if (pay_mode == "C") {
document.getElementById("Cash").checked = true;
chMd();
} else {
document.getElementById("Cheque").checked = true;
chMd();
}
});
</script>
<强>控制器
ViewData["Cu_Name"] = CustName;
查看
<script type="text/javascript" language="javascript">
$(function () {
$('#Cust_Id').change(function () {
var val = ($(this).find(":selected").text());
document.getElementById("Cust_Name").value = val;
});
});
</script>
