Hi Narvish,
First thing I would like to bring here is you are posting the data so the ajax type should be "POST" with a [HttpPost] attribute on the ActionMethod and also check if the Form identifier is frm1.
Your ajax should look like:-
$.ajax({
url:'THE URL',
type:"POST",
data:$("#frm1").serialize(),
success:function(data){
}
});
Check for the form also
<form id="formPost">
....
....
</form>
I hope you get me here.
Please post back your queries if any.
Thanks.
