简易日期控件制作~~

1。添加几个控件（.aspx）

< asp:TextBox runat = " server "  ID = " txtMyTextBox " >
     </ asp:TextBox >
     < asp:ImageButton runat = " Server "  ID = " ibtnDepartDate "  ImageUrl = " ~/Images/calendar.gif "
                                        OnClick = " calImageButton_Click "   AlternateText = " Click Here " />
     < asp:Calendar runat = " server "  ID = " calMyCalendar "   Visible = " False "
OnDayRender = " myDayRenderMethod "  OnSelectionChanged = " calMyCalendar_SelectionChanged "
BackColor = " White "  BorderColor = " #3366CC "  BorderWidth = " 1px "  CellPadding = " 1 "
DayNameFormat = " Shortest "  Font - Names = " Verdana "  Font - Size = " 8pt "  ForeColor = " #003399 "
 Height = " 200px "  Width = " 220px " >
         < SelectedDayStyle BackColor = " #009999 "  Font - Bold = " True "  ForeColor = " #CCFF99 "   />
         < TodayDayStyle BackColor = " #99CCCC "  ForeColor = " White "   />
         < SelectorStyle BackColor = " #99CCCC "  ForeColor = " #336666 "   />
         < WeekendDayStyle BackColor = " #CCCCFF "   />
         < OtherMonthDayStyle ForeColor = " #999999 "   />
         < NextPrevStyle Font - Size = " 8pt "  ForeColor = " #CCCCFF "   />
         < DayHeaderStyle BackColor = " #99CCCC "  ForeColor = " #336666 "  Height = " 1px "   />
         < TitleStyle BackColor = " #003399 "  BorderColor = " #3366CC "  BorderWidth = " 1px "  Font - Bold = " True "
            Font - Size = " 10pt "  ForeColor = " #CCCCFF "  Height = " 25px "   />
     </ asp:Calendar >

 2。添加事件（.cs）

     protected   void  calImageButton_Click( object  sender, ImageClickEventArgs e)
     ... {
        calMyCalendar.Visible = true;
    }
     protected   void  calMyCalendar_SelectionChanged( object  sender, EventArgs e)
     ... {
        if (calMyCalendar.Visible == true)
        ...{
            txtMyTextBox.Text = calMyCalendar.SelectedDate.ToString("dd/MM/yyyy");
            calMyCalendar.Visible = false;
        }

    }

3.使某些日期不可选择

     private   int  _nDaysToBlock;
     protected   void  Page_Load( object  sender, EventArgs e)
     ... {
        _nDaysToBlock = 7;
    }
   
  protected   void  myDayRenderMethod( object  sener, DayRenderEventArgs e)
     ... {

        if (e.Day.Date < (System.DateTime.Now.AddDays(_nDaysToBlock)))
        ...{
            e.Day.IsSelectable = false;
            e.Cell.Font.Strikeout = true;
        }
    }
