Hello, 

I got a custom button on my toolbar , which opens a modal, but , when i tried to open in mobile mode , it stops working

see the code below

    $('#pdfViewer').css('width', '100%');
    var request = new XMLHttpRequest();
    request.responseType = 'blob';
    request.onload = function () {
        var reader = new FileReader();
        reader.readAsDataURL(request.response);
        reader.onload = function (e) {
            $("#pdfViewer").kendoPDFViewer({
                pdfjsProcessing: {
                    file: {
                        data: e.target.result.split(",")[1]
                    }
                },
                toolbar: {
                    items: [ 
                        "zoomInOut",
                        {
                            type: "button",
                            name: 'Description',
                            template: '<button type="button" onclick="openModal()" title="Description" class="k-button k-button-md k-button-flat" id="btn-Description"><span class="k-icon k-i-toc-section-level"></span></button>',
                        }
                    ]
                },
                width: "100%",
                height: 760
            }).getKendoPDFViewer();
        };
    };

on browser desktop modal it works normally

Hello

how can I bind to the Click-Event of zoomIn or zoomOut for the standard zoom toolbar or PdfViewer ?

Somehow similar to 

var pdfViewer = $("#pdfviewer").data("kendoPDFViewer");
pdfViewer.toolbar.zoom.combobox.bind("change", onChangeZoom_Pdf); 

Regards

Christine
