Hi Guys,

I have one dropdown (id - ddlnoofchild) and one radio button list in my asp.net form.
I want a javaScript function, which will make the radio button list mandatory if user selects any item from the dropdown.

What is the script for that ?

Do you want to inform users that RadioButtonList is to be selected if they select a dropdown or you want that to happen programmatically?

Hi,
You can fire "onchange" event of javascript. Here you go with the examples.

XML

<script type="text/javascript" >
        function myFunc()
        {

         var selectedDdl = $("option:selected", "#ddlnoofchild").text();
           if (selectedDdl == "ddltext")
            {
                $(":radio").each(function ()
                {
                    $(this).removeAttr("disabled");
                });

            }


        }
    </script>

Put your value in place of ddltext

hey shinebudy try this:

HTML

checkedvar=$('input[name=RadioButtonList1]:checked').val();

put your radio button id in place of "RadioButtonList1"
