Yes, it doesn't work.
This code returns a DateRangeField instance. This widget is defined in the calendar's sources. You can review them to get a representation how this widget looks.
this.get(0).get(1)
So, I can suggest to handle 'render' event of this field to get what you want.
Here you are.
Example
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

return CompanyX.EventEditWindow1;
},
dayClick : function (cal, dt, allDay, el) {
this.record.show.call(this, cal, { StartDate: dt, IsAllDay: allDay }, el);
},
record : {
show : function (cal, rec, el) {
CompanyX.getWindow().show(rec, el);
}
}
};
</script>

this.get(0).get(1).on('render', function () {

this.endTime.setReadOnly(true);

To get the info why I use .setDisabled() for a checkbox, please follow:
