Join Query Multiple Tables Order by descending Order

var year = (from ep in _adminContext.table1

                    join e in _adminContext.table2 on ep.idequals e.id

                    join t in _adminContext.table3 on e.idequals t.id

                    orderby t.Date descending

                    where t.status == "A"

                    select new

                    {

                        id= ep.id

asynchronous option to be false

the asynchronous choice to be false to induce a synchronous Ajax request. Then your asking will set some information before your Main perform return.
Here's what your code would seem like if modified as suggested:

beforecreate: function (node, targetNode, type, to) {

    jQuery.ajax({

            url: 'http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value),

            success: function (result) {

            if (result.isOk == false) 

                 alert(result.message);

            },

            async: false

         });

}

<script>

    // ...

    $.ajax(... async: false ...); // Hey browser! first complete this request,

                                  // then go for other codes

    $.ajax(...); // Executed after the completion of the previous async:false request.

</script>

Difference between Managed and unmanaged code

Difference between Managed and unmanaged code

Managed code - Executed by the CLR instead of being executed by the operating system.

Unmanaged code - Executed directly by the operating system(OS) and not by the CLR
