在Visual Studio for it 2012中使用日历控件,我可以从SQL Server 2012数据库中获取日期(即至今和从日期开始并突出显示日历中的日期)我还可以突出显示到日期和从日期之间的日期。
总之,在我的日历中,我的日期02/10/2013(迄今为止)和04/10/2013(从日期开始)在日历中突出显示日期和这些日期之间的日期。并且还突出显示了2013年10月15日(迄今为止)和2013年10月19日(从日期开始),并突出显示了这些日期之间的日期。
但是我希望能够随机更改日历中每个选定日期块的背景颜色?我该怎么做?
非常感谢
这里有一些代码,用背面颜色突出显示日期并使它们可选择等等。这段代码完全正常,但我希望能够做到以上几点?
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (dsHolidays != null)
{
foreach (DataRow dr in dsHolidays.Tables[0].Rows)
{
DateTime nextDate;
DateTime endDate;
nextDate = (DateTime)dr["date"];
endDate = (DateTime)dr["date1"];
if (nextDate <= e.Day.Date && endDate >= e.Day.Date)
{
e.Cell.BackColor = System.Drawing.Color.Gray;
// dates are unselectable
e.Day.IsSelectable = false;
}
}
}
// makes the all the first dates selectable
foreach (DataRow dr in dsHolidays.Tables[0].Rows)
{
DateTime nextDate1;
nextDate1 = (DateTime)dr["date"];
{
if (e.Day.Date == nextDate1)
{
e.Day.IsSelectable = true;
e.Cell.ForeColor = System.Drawing.Color.Blue;
}
}
}
}

也许这段代码可以提供帮助
Random randomGen = new Random();
KnownColor[] names = (KnownColor[])Enum.GetValues(typeof(KnownColor));
Color newColor = Color.FromKnownColor(names[randomGen.Next(names.Length)]);
