Please try it
without the
dataType and
contentType on Ajax method. :)
function ddlChange() {
var check = @Html.Raw(val);
$.ajax({
async: false,
url: '/Main/LoadddlView',
data: '{model:' + JSON.stringify(check) + '}',
type: 'POST',
success: function (objOperations) {
$("#myPartialViewDiv").html(objOperations);
}
});
}
