                success: function(data){
                    var frameSet = document.getElementById("editFaxFrame");
                    var iframedoc = frameSet.document;

                    if (frameSet.contentDocument)
                        iframedoc = frameSet.contentDocument;
                    else if (frameSet.contentWindow)
                        iframedoc = frameSet.contentWindow.document;

                    if (iframedoc){
                        iframedoc.open();

                },
                error: function () {
                    window.location.href = '@Url.Action("Index","Error")';
                }
            });
        },

I solved This Issue after so much r&d i put Settimeout() function on ajax success

 $('#editFaxdialog').dialog({
        autoOpen: false,
        title: 'Edit PDF',
        height: 'auto',
        width: '80%',
        position: ['top', 50],
        draggable: false,
        show: 'blind',
        hide: 'blind',
        modal: true,
        open: function (event, ui) {
            $.ajax({
                url: '@Url.Action("EditPdf", "Fax")',
                type: 'GET',
                cache:false,
                success: function(data){
                    setTimeout(function () {
                    var frameSet = document.getElementById("editFaxFrame");
                    var iframedoc = frameSet.document;

                    if (frameSet.contentDocument)
                        iframedoc = frameSet.contentDocument;
                    else if (frameSet.contentWindow)
                        iframedoc = frameSet.contentWindow.document;

                    if (iframedoc){
                        iframedoc.open();
                        iframedoc.writeln(data);
                        iframedoc.close();
                    }
},400);
                },
                error: function () {
                    window.location.href = '@Url.Action("Index","Error")';
                }
            });
        },
        close: function (event, ui) {
            $("#editFaxFrame").attr("src", '');
        }

    });
