What I have tried:

i have been change into routeconfig as well as action parameters (int? id) but still not resolved issue.. and did ajax jquery code for fetch id ..


view code:

<input type="submit" id="btnapprove" onclick="holidayapprove(@data.Id);"> 

function holidayapprove(Id) {
$.ajax({
type: "POST",
url: '@Url.Action("Holiday_approve", "holiday_schedule")',
cache: false,
data: { Id:Id},
success: function (result) {

},
failure: function (result) {
alert("Server Error");
}
});
}
