function selectRadioButton()
{

var y=document.getElementById("ctl00_ContentPlaceHolder1_rbyes");
var n=document.getElementById("ctl00_ContentPlaceHolder1_rbno");


if(y.checked==false && n.checked==false)
{
alert(Please select Yes/No");
return false;
}
return true;
}

<asp:RadioButton  runat="server" ID="rbyes" Text="Yes"  visible="true" GroupName="a"  />
 <asp:RadioButton  runat="server" ID="rbno" Text="No" visible="true" GroupName="a" />
 <asp:Button  ID="btnOk" runat="server" Text="OK" OnClick="btnOk_Click"  OnClientClick="return selectRadioButton();"/>
