You can validate the same using the JQuery code.


if($('.dropDownName > option[value!=""]').length == 0) {

Hi,

Check the code,same code u can use for Silverlight also.

$(document).ready(function(){
$('#BtnSubmit').click(){
var value = $('#combobox').val();
if (value == -1)
{
alert('select combo value');
return false;
}
else
{
return true;
}
});

});

Note: "BtnSubmit" is the id of Submit buttom and "City" is the id of Combobox

and use code behind like this:
<select name="title" id="combobox">
<option value="0">Select one...</option>
<option value="-1">Select one...</option></select>

Note: you can give index 0 or -1 to the select option of combo box

hope its helpful for you..

Thanks,
