CustomCalendar.cs problem

Sarah-WCHM · September 16th, 2004, 01:29 PM

Hey all,

I'm having a problem with the custom calendar ... once I switch from the original calendar to the custom one, no calendar displays! This happens when I use the code included in the complete code download as well. I'm using the C# version of the book.

Any help would be appreciated--Code follows.

// CustomCalendar.cs
//

namespace WroxUnited
{
  using System;
  using System.ComponentModel;
  using System.Web.UI;
  using System.Collections;
  using System.Web.UI.WebControls;

  public class CustomCalendar : Control, INamingContainer
  {
    private Calendar calendar;
    public event EventHandler SelectionChanged;
    private Hashtable _dateList;

    public Hashtable DateList
    {
      get
      {
        return _dateList;
      }
      set
      {
        _dateList = value;
      }
    }

    public DateTime SelectedDate
    {
      get
      {
        return calendar.SelectedDate;
      }
    }

    protected override void CreateChildControls()
    {
      calendar.CssClass = "calendar";
      calendar.DayStyle.CssClass = "normaldate";
      calendar.OtherMonthDayStyle.CssClass = "othermonthdate";
      this.Controls.Add(calendar);
    }

    protected override void OnInit(EventArgs e)
    {
      base.OnInit(e);

      calendar = new Calendar();

      calendar.DayRender += new DayRenderEventHandler(this.EventCalendar_DayRender );
      calendar.SelectionChanged += new EventHandler(this.EventCalendar_SelectionChanged);
    }

    private void EventCalendar_DayRender(object sender, DayRenderEventArgs e)
    {
      if (_dateList != null)
      {
        if (_dateList[e.Day.Date] != null)
        {
          e.Cell.CssClass = "selecteddate";
          e.Day.IsSelectable = true;
        }
        else
        {
          e.Day.IsSelectable = false;
        }
      }
      else
      {
        e.Day.IsSelectable = false;
      }
    }

    private void EventCalendar_SelectionChanged(object sender, EventArgs e)
    {
      if (SelectionChanged != null)
      {
        SelectionChanged(this, e);
      }
    }
  }
}
