如何使验证控件可见 [英] How to make the validation control to visible true

在我的应用程序中，我使用单选按钮列表，其中两个列表项分别为是"和否".
如果用户单击是"，则我正在启用该文本​​框，对于该文本框，我已将requiredfield验证和comparevalidation控件设置为可见false为默认值.
当用户单击是"单选按钮时，我要启用文本框并使验证控件在Javascript中显示为true.谁能帮我解决这个问题.
这是代码:

Hi,

In my application I am using the radiobutton list with two list item as Yes and No.
If the user clicks on yes I am enabling the textbox, for this text box I have set the requiredfield validation and comparevalidation controls with visible false as default.
When the user clicks the Yes radiobutton I want to enable the textbox and make the validation controls as visible true in Javascript. Can anyone help me to solve this problem.
Here is the code:

function EMD_OnClick(val) 
{
 if (val == 'Y') 
 {
    document.getElementById("<%=drpEMDCurrency.ClientID %>").disabled = false;
    document.getElementById("<%=drpEMDCurrency.ClientID %>").focus();
    document.getElementById("<%=txtEMDValue.ClientID %>").disabled = false;
    document.getElementById("<%=rqdEMD.ClientID %>").style.display = "";
    document.getElementById("<%=cmpEMDValue.ClientID %>").style.display = "";
 }
 else if (val == 'N') 
 {
    document.getElementById("<%=drpEMDCurrency.ClientID %>").disabled = true;
    document.getElementById("<%=txtEMDValue.ClientID %>").disabled = true;
    document.getElementById("<%=rqdEMD.ClientID %>").style.display = "none";
    document.getElementById("<%=cmpEMDValue.ClientID %>").style.display = "none";
 }
}

在此先感谢

Thanks in Advance
