设置日期范围以显示在日历中

Question

I have this asp.net calendar control:

<asp:Calendar runat="server" ID="calendar" SelectionMode="Day" ondayrender="DateRange" />

and its code behind:

protected void DateRange(object sender, DayRenderEventArgs e)
{
    //do some codes here to set the range of the calendar to display
}

I haven't implemented anything to my DateRange cause I don't know the algorithm of it.

If I want my calendar control to display only specific month and days:

Example: Display only the ranges (July 04, 2015 - March 15, 2016) //Nothing follows

Is it possible to alter the default calendar method to display only the specific months,days above?

Please help, I'm new to calendar event and its built in functions in c#.

You can't change what but only how it is displayed and you can make it unselectable:

protected void DateRange(object sender, DayRenderEventArgs e)
{
    DateTime rangeStart = new DateTime(2015, 7, 4);
    DateTime rangeEnd   = new DateTime(2016, 3, 15);

    if (e.Day.Date < rangeStart || e.Day.Date > rangeEnd)
    {
        e.Day.IsSelectable = false;
        e.Cell.ForeColor = System.Drawing.Color.Gray;
    }
}
