1)要自定义约会表单，请使用onAppointmentFormCreated事件。也可以看到demo。
2)要将计划程序导航到特定日期，请使用currentDate选项。下面的示例显示了如何使用onContentReady选项执行此操作：

$("#scheduler").dxScheduler({
    /*...*/
    // set default current date too old for demo
    currentDate: new Date(2010, 4, 18),
    onContentReady: function(e) {
        // get all loaded appointments
        var appointments = e.component.getDataSource().items();
        // navigate to the first appointment
        e.component.option("currentDate", new Date(appointments[0].startDate));
    }
});

更改排定程序属性对话框的示例：

$("#scheduler").dxScheduler({
    dataSource: ...
    onAppointmentFormOpening(e) {
        var form = e.form;
        form.beginUpdate();

        form.option("colCountByScreen", { lg: 1, xs: 1 });
        form.getEditor("repeat").option("value", true); 
        form.itemOption("mainGroup.allDay", "visible", false); 
        form.itemOption("mainGroup.description", "visible", false);

        form.endUpdate();
   },
});
