ASP.NET Tips: Create a Personalized Calendar for Blog

Author：Eve Cole Update Time：2009-06-30 15:27:50

The calendar control is one of the controls that comes with .net. It has powerful functions and is used in many project developments. It is even more essential for blog systems. Even good jade still needs to be carved. In order to make it more beautiful and practical, we also need to carry out secondary development on it.

Create a new user control and bring in the calender control. The first step is to set the appearance. Based on your needs, you only need to make some adjustments to its related properties. The picture below is the interface after I adjusted it

The properties are set as follows:

＜asp:calendar id="Calendar1" CellPadding="2" Width="160px" TitleStyle-BackColor="#000000"
BorderColor="#aaaaaa"
DayHeaderStyle-BackColor="#5e715e"
OtherMonthDayStyle-ForeColor="#cccccc"
DayNameFormat="Full"
runat="server"
TitleStyle-ForeColor="#ffffff"
NextPrevStyle-ForeColor="#ffffff"
CellSpacing="1"
WeekendDayStyle-BackColor="#eeeeee"
DayHeaderStyle-ForeColor="#ffffff"
SelectionMode="None"
TodayDayStyle-BorderColor="#5e715e"
TodayDayStyle-BorderWidth="1"
TodayDayStyle-Font-Bold="true"
TodayDayStyle-ForeColor="#5e715e"
＞

The second step is to adjust the internal functions. This work mainly focuses on the processing of the following two events.

PreRender: Occurs when the server control is about to be rendered to its containing Page object.

DayRender: Occurs when each day is created for the Calendar control in the control hierarchy.

First define three integer variables and integer arrays

private int[] arrCurrentDays, arrPreDays, arrNextDays; //The three variables are the current month, the previous month, and the next month.
private int intCurrentMonth,intPreMonth,intNextMonth; //Three integer arrays store the relative month dates with blogs written on them
protected System.Web.UI.WebControls.Calendar Calendar1; //This is our calendar control

2. Below I will give the source code of these two events respectively, and explain the functions they implement below. If you don’t understand, you can read the explanation below first.

PreRender

private void Calendar1_PreRender(object sender, System.EventArgs e)
{
Thread threadCurrent = Thread.CurrentThread;
CultureInfo ciNew = (CultureInfo)threadCurrent.CurrentCulture.Clone();
ciNew.DateTimeFormat.DayNames = new string[]{"Day","One","Two","Three","Four","Five","Six"};
ciNew.DateTimeFormat.FirstDayOfWeek = DayOfWeek.Sunday;
threadCurrent.CurrentCulture = ciNew;
}

The above code changes the display of week names. You can change the name display simply by changing the value of the character array.

DayRender

private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
//This control occurs every day when it is created.

CalendarDay d = ((DayRenderEventArgs)e).Day;
TableCell c = ((DayRenderEventArgs)e).Cell;
}
