Cordova calendar plugin for Windows Phone 8

If you worked with Cordova/Phonegap and came across calendar plugin for Windows Phone 8 you must be knowing that Windows Phone 8 does not support calendar plugin officially and there is no plugin in Cordova plugin registry. As a workaround I wrote native plugin to add appointments to device calendar and thought to share it with my readers in quickie blog. 🙂

Create a new cs file in plugins directory named AddCalendarEvents.cs and add following code-

using Microsoft.Phone.Tasks;
using Microsoft.Phone.UserData;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using WPCordovaClassLib.Cordova;
using WPCordovaClassLib.Cordova.Commands;
using WPCordovaClassLib.Cordova.JSON;

namespace Cordova.Extension.Commands {
	public class AddCalendarEvents: BaseCommand {
		public void addCalendarEvents(String str) {
			string[] calendarValues = str.Split('|');

			SaveAppointmentTask saveAppointmentTask = new SaveAppointmentTask();

			int appointmentYear = Int32.Parse(calendarValues[3]);
			int appointmentMonth = Int32.Parse(calendarValues[4]);
			int appointmentDate = Int32.Parse(calendarValues[5]);
			float appointmentTime = float.Parse(calendarValues[6]);

			DateTime scheduleApptDateStart = (new DateTime(appointmentYear, appointmentMonth, appointmentDate, 7, 0, 0)).AddHours(appointmentTime);
			DateTime scheduleApptDateEnd = (new DateTime(appointmentYear, appointmentMonth, appointmentDate, 7, 30, 0)).AddHours(appointmentTime);
			saveAppointmentTask.StartTime = scheduleApptDateStart;
			saveAppointmentTask.EndTime = scheduleApptDateEnd;
			saveAppointmentTask.Subject = calendarValues[1];
			saveAppointmentTask.Location = calendarValues[2];
			saveAppointmentTask.Details = "";
			saveAppointmentTask.IsAllDayEvent = false;
			saveAppointmentTask.Reminder = Reminder.FifteenMinutes;
			saveAppointmentTask.AppointmentStatus = Microsoft.Phone.UserData.AppointmentStatus.Busy;
			saveAppointmentTask.Show();
		}

		public void getCalendarEventData(String str) {
			ButtonAppointments_Click();
		}

		private void ButtonAppointments_Click() {
			Appointments appts = new Appointments();

			//Identify the method that runs after the asynchronous search completes.
			appts.SearchCompleted += new EventHandler < AppointmentsSearchEventArgs > (Appointments_SearchCompleted);

			DateTime start = DateTime.Now;
			DateTime end = start.AddDays(7);
			int max = 20;

			//Start the asynchronous search.
			appts.SearchAsync(start, end, max, "Appointments Test #1");
		}

		void Appointments_SearchCompleted(object sender, AppointmentsSearchEventArgs e) {
			//Do something with the results.
			//MessageBox.Show(e.Results.Count().ToString());
			try {
				e.Results.ToList();
				MessageBox.Show("Success");
			} catch (System.Exception) {}

		}
	}
}

Refer plugin in config.xml-

<feature name="AddCalendarEvents">
        <param name="wp-package" value="AddCalendarEvents" />
        <param name="onload" value="true" />
    </feature>

 

If you have basic knowledge of Cordova it should not be tough.

You can call it using

var inputCalendarString = notes + '|' + title + '|' + location + '|' + appointmentDate.getFullYear() + '|' + (appointmentDate.getMonth() + 1) + '|' + appointmentDate.getDate() + '|' + '1.0' + '|' + ' ';
cordova.exec(null, null, "AddCalendarEvents", "addCalendarEvents", inputCalendarString);

It works for one event but if you have loop of events it will not work. To support multiple events, you can maintain Localstorage flag & data with current index of events data. Use resume callback to add rest of the events using custom appointment plugin that you wrote. Each time your app resumes you increment index and add events data from next index.

document.addEventListener('resume', this.resumeApp, false)
resumeApp: function () {
if (localStorage.getItem('updatecalendar') == 'false') {
syncUpdatedCalendarWP8();
      }
}

Happy Coding!

Windows 8- Quick look at Metro style design

Before release of Windows 8 expected to launch by November 2012, here’s quick review of its release preview known for its sleek and classic Swiss graphic design named “METRO”.

Social Networking

Metro style gallery for Facebook looks great. The whole user experience is re innovated. Flow is smooth, you will just love social networking experience on Windows 8.

The start menu

Again, the start menu is completely re innovated. The global search can search internet, store, computer, programs. Everything you need to operate your computer.

Store

For now there are no paid apps. Microsoft and other developers have lot of expectations from Metro Style UI Design. A key design principle of Metro is better focus on the content of applications, relying more on typography and less on graphics. I am exploring few good apps. Will come up with metro style apps review in future blogs.Image

The innovation here is the fluidity of experience and focus on the data, without using traditional user interface conventions of windows and frames. Data becomes the visual elements and controls. Simple gestures and transitions guide the user deeper into content. A truly elegant and unique experience.
