function checkIsIE() {
    var isIE = false;
    if (navigator.userAgent.indexOf('MSIE') !== -1 || navigator.appVersion.indexOf('Trident/') > 0) {
        isIE = true;
    }
    if (isIE)  // If Internet Explorer, return version number
    {
        kendo.ui.Window.fn._keydown = function (originalFn) {
            var KEY_ESC = 27;
            return function (e) {
                if (e.which !== KEY_ESC) {
                    originalFn.call(this, e);
                }
            };
        }(kendo.ui.Window.fn._keydown);

        var windowBrowser = $("#windowBrowser").kendoWindow({
            modal: true,
            id: 'dialogBrowser',
            visible: false,
            width: "40%",
            title: "Thông báo",
            scrollable: false,
            resizable: false,
            deactivate: false,
            position: {
                top: 100,
                left: '30%'
            }
        }).data('kendoWindow');
        var html = '
Please use the browser below to use the tool
';
        html += '';
        html += ' ';
        html += ' ';
        html += '
';
        windowBrowser.content(html);
        windowBrowser.open();

        $("#windowBrowser").parent().find(".k-window-titlebar").remove();
    }
    else  // If another browser, return 0
    {
        return false;
    }
}
