Hey Guys,

I'm starting a WPF project, and just finished the base of the UI, it seems very convoluted though, so I'm not sure if I've gone around laying it out in the right way. I don't want to get to start developing the back-end and realise that I've done the front wrong, and make life harder for myself.

Coming from a background of <DIV>'s and CSS to style this is a lot different, and really want to get it right from the start.

Essentially it's a one week calendar (7 days, Mon-Sunday, defaulting to the current week.) Which will eventually link up to a DB and if I have an appointment for something on this day it will show it in the relevant day.

I've opted for a Grid rather than ListView because of the way it will work I will not be binding the results to a collection or anything along those lines. Rather I will be filling out a Combo box within the canvas for each day (yet to be placed in the code) for each event and on selection it will show me further details.

XAML:

CS:

    public partial class Window1 : Window {
        private DateTime today = new DateTime();
        private Label[] Dates = new Label[7];
        public Window1() {
            DateTime start = today = DateTime.Now;
            int day = (int)today.DayOfWeek;
            while (day != 1) {
                start = start.Subtract(new TimeSpan(1, 0, 0, 0));
                day--;
            }
            InitializeComponent();
            Dates[0] = lblMondayDate;
            Dates[1] = lblTuesdayDate;
            Dates[2] = lblWednesdayDate;
            Dates[3] = lblThursdayDate;
            Dates[4] = lblFridayDate;
            Dates[5] = lblSaturdayDate;
            Dates[6] = lblSundayDate;
            FillWeek(start);
        }

        private void FillWeek(DateTime start) {
            for (int d = 0; d < Dates.Length; d++) {
                TimeSpan td = new TimeSpan(d, 0, 0, 0);
                DateTime _day = start.Add(td);
                if (_day.Date == today.Date) {
                    Canvas dayCanvas = (Canvas)Dates[d].Parent;
                    dayCanvas.Style = (Style)this.Resources["Today"];
                }
                Dates[d].Content = (int)start.Add(td).Day;
            }
        }
    }
