Right now I have a calender that only displays one month(what ever month I pass in). I'm trying to let the user pick what month and year from a comboBox and have the calender update. I'm binding using observablecollection which I'm sort of familiar with. I have no clue how INotifyPropertyChanged works though. I've never used it before. Any help or advice is greatly appreciated. This is what I have so far:
public class Schedule : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public void Update(int propertyName)
{
if (propertyName != null)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null)
handler.Invoke(this, new PropertyChangedEventArgs(propertyName.ToString()));
}
}
// public void UpdateCal(PropertyChangedEventArgs e)
// {
// if (PropertyChanged != null)
// PropertyChanged(this, e);
// }
public string MonthWeek { get; set; }
public string Year { get; set; }
public string Month { get; set; }
public string day { get; set; }
public string WeekOfYear { get; set; }
public string dayofweek { get; set; }
// public string month {
// get {return Month; }
// set
// {
// UpdateCal(new PropertyChangedEventArgs("month"));
// }
// }
public int WeekNo { get; set; }
public int WeekDay { get; set; }
public DateTime Date { get; set; }
}
---This is another class that figures out where to place each date on the grid----
public SchedulePage(MainWindow parentForm)
{
InitializeComponent();
pick = Convert.ToInt32(comboMonth.SelectedItem) + 1;
_parentForm = parentForm;
// DateTime date = new DateTime(year, month, day);
var t = new List<Schedule>();
DateTime curr = DateTime.Now;
// comboMonth.Items.Add(curr.Month);
DateTime newcurr = new DateTime(2011, pick, 1);
// pickdate = datePickercal.SelectedDate;
// DateTime newcurr = new DateTime(curr.Year, curr.Month, 1);
var cal = System.Globalization.DateTimeFormatInfo.CurrentInfo.Calendar;
var ms = cal.GetWeekOfYear(new DateTime(newcurr.Year, newcurr.Month, 1), System.Globalization.CalendarWeekRule.FirstDay, System.DayOfWeek.Sunday);
for (var i = 1; newcurr.Month == pick; newcurr = newcurr.AddDays(1))
{
var sched = new Schedule();
var month_week = (newcurr.Day / 7) ;
sched.MonthWeek = newcurr.GetWeekOfMonth().ToString();
sched.Month = newcurr.Month.ToString();
sched.Year = newcurr.Year.ToString();
sched.day = newcurr.Day.ToString();
sched.WeekOfYear = cal.GetWeekOfYear(newcurr, System.Globalization.CalendarWeekRule.FirstDay, DayOfWeek.Sunday).ToString();
sched.dayofweek = newcurr.DayOfWeek.ToString();
t.Add(sched);
_parentForm.bindings.schedule.Add(new Schedule { WeekNo = newcurr.GetWeekOfMonth()-1, WeekDay = (int)newcurr.DayOfWeek, day = newcurr.Day.ToString() });
}
lblDate.Content = (newcurr.Month -1) + "/" + newcurr.Year;
DataContext = _parentForm.Bindings;
---And this class makes the observablecollections-----
public partial class BindingCamper
{ // This class assist in binding campers from listview to the textboxes on the camperspage
public ObservableCollection<Camper> Campers { get; set; }
public ObservableCollection<Staff> StaffMembers { get; set; }
public ObservableCollection<Schedule> schedule { get; set; }
public BindingCamper()
{
Campers = new ObservableCollection<Camper>();
StaffMembers = new ObservableCollection<Staff>();
schedule = new ObservableCollection<Schedule>();
}
