Hi,
I am trying to visualize the fact that some dates are unavailable. I first tried to do this in Calendar_DayRender, but I was only able to disable the dates, not colorize them.

I then tried Calendar_PreRender, and added all unavailable dates (with formatting) into the calendars SpecialDays. What happened then was
1. still only disabled, no color.
2. when I go to next month, the backcolor appears. it then stays, and works ok.
3. ForeColor is never set. It seems that <span> overrides the styling. css for span is set by Telerik.

Any suggestions on how to fix this?

Hi Terje ,

In order to change the background color of RadCalendar from code behind please try the following C# code snippet.

C#:
protected void rcalendarDemo_PreRender(object sender, EventArgs e)
{
    rcalendarDemo.CalendarTableStyle.BackColor = System.Drawing.Color.SeaGreen;
}

To change the ForeColor as a workaround please try the below CSS.

CSS:
.RadCalendar .rcRow a
{
    color : Red !important;
}

Thanks,
Shinu.

Hi Shinu,

Thank you for your reply.

My problem is that I want to change the colours on some dates, not the whole calendar.

Here is my code:
01.protected void Calendar_PreRender(object sender, EventArgs e)
02.{
03.    if (_blockings == null && _bookings == null) return;
04.    var cal = (RadCalendar) sender;
05.    cal.CalendarTableStyle.BackColor = Color.SeaGreen;
06.    cal.SpecialDays.Clear();
07.    cal.SpecialDays.AddRange(BlockedDates());
08.    cal.SpecialDays.AddRange(BookedDates());
09.}
10. 
11.private RadCalendarDay[] BlockedDates()
12.{
13.     
14.    var cal = new List<RadCalendarDay>();
15.    foreach (var blocked in _blockings)
16.    {
17.        if (blocked.From_date == null || blocked.To_date == null) continue;
18.        for (var day = blocked.From_date.Value; day < blocked.To_date.Value; day = day.AddDays(1))
19.        {
20.            cal.Add(FormatDate(day, Color.DarkOrange, Color.White));
21.        }
22.    }
23.    var days = cal.ToArray();
24.    return days;
25.         
26.}
27. 
28.private RadCalendarDay[] BookedDates()
29.{
30.    var cal = new List<RadCalendarDay>();
31.    foreach (var booking in _bookings)
32.    {
33.        if (booking.From_date == null || booking.To_date == null) continue;
34.        for (var day = booking.From_date.Value; day < booking.To_date.Value; day = day.AddDays(1))
35.        {
36.            cal.Add(FormatDate(day, Color.DarkRed, Color.White));
37.        }
38.    }
39.    var days = cal.ToArray();
40.    return days;
41.}
42. 
43.private RadCalendarDay FormatDate(DateTime day, Color backColor, Color foreColor)
44.{
45.            var calDay = new RadCalendarDay {Date = day, IsSelectable = false, IsDisabled = true};
46.            calDay.ItemStyle.BackColor = backColor;
47.            calDay.ItemStyle.ForeColor = foreColor;
48.    return calDay;
49.}

Hi Terje,

The best approach for adding days to the SpecialDays collection is on Page_Load event. Please have a look into the below code snippet which works fine at my end.

C#:
public DateTime[] specialDates = { DateTime.Now, DateTime.Now.AddDays(-2), DateTime.Now.AddDays(2) };
protected void Page_Load(object sender, EventArgs e)
{
    List<RadCalendarDay> myDays = new List<RadCalendarDay>();
    foreach (DateTime date in specialDates)
    {
        RadCalendarDay oneDay = new RadCalendarDay();
        oneDay.Date = date;
        oneDay.ItemStyle.CssClass = "special-days";
        myDays.Add(oneDay);
    }
    rcalendarDemo.SpecialDays.AddRange(myDays.ToArray());
}

CSS:
.special-days a
{
    color: Red !important;
    background-color: Black !important;
}

Thanks,
Shinu.

Hi again, and thank you for trying :)

If you try to combine your answers, then you will see my dilemma. I am not able to put colours to a disabled date. I would also like to be able to have different colours for different meanings. Ex (red for occupied, orange for blocked, gray for unavailable).

Thanks,

Terje K.

Hi Terje,

Please have a look into the below code snippet to style the disabled day in a RadCalendar.

ASPX:
<telerik:RadCalendar ID="rcalendarDemo" runat="server">
    <DisabledDayStyle CssClass="blocked" />
</telerik:RadCalendar>

C#:
public DateTime[] blocked = {  DateTime.Now.AddDays(-3), DateTime.Now.AddDays(3) };
protected void Page_Load(object sender, EventArgs e)
{
    List<RadCalendarDay> blockedDates = new List<RadCalendarDay>();
    foreach (DateTime date in blocked)
    {
        RadCalendarDay oneDay = new RadCalendarDay();
        oneDay.Date = date;
        oneDay.IsDisabled = true;
        blockedDates.Add(oneDay);
    }
    rcalendarDemo.SpecialDays.AddRange(blockedDates.ToArray());     
}

CSS:
.blocked a
{
    color: Orange !important;
}

Hope this will helps you.
Thanks,
Shinu.

Hi again Shinu.

Very nice, but this will not make it possible to have different colors for different meanings. I did get it to work by using template, but somehow the ToDate_Calendar looses its color when I ​select a date in FromDate_Calendar.

Here is my code.
01.<telerik:RadCalendar ID="FromDate" RangeMinDate="<%# DateTime.Today %>" OnDayRender="Calendar_DayRender" runat="server" SelectedDate="<%# DateTime.Today %>" Enabled="False"

I did use the formatting tool. The problem is probably to do with setting the height parameter...

Im on holiday now, so i dont have access to the code. I Will repost it without height parameter when i get back next week. 

And to telerik: typing on the forum with a mobile phone is typing blind. Cant See what I write. Cant See what others have written while answering...

Hi Terje,

In order to style the disabled dates please try the below CSS which works fine at my end.

CSS:
.rcDisabled
{
    background-color: darkorange;
    color: white;
    font-style: italic;
}

Thanks,
Shinu.

Hi again.

Everything seems to work fine in the first calendar (from-date), but as soon as I click a date on the first calendar, all formatting disappears from the second calendar (to-date). Even the formatting from your suggestion disappears.

I have attached screenshots of how it looks on init (oninit.png) and after dateselection in first calendar (onclick.png)

Hi Terje,

Unfortunately I couldn't replicate the issue at my end. Please have a look into the sample code snippet which works fine at my end.

ASPX:
<telerik:RadCalendar ID="FromDate" OnDayRender="Calendar_DayRender" runat="server"  EnableAriaSupport="True" EnableShadows="True" AutoPostBack="True" EnableMultiSelect="False" ShowOtherMonthsDays="False" RangeMinDate="<%# DateTime.Today %>" SelectedDate="<%# DateTime.Today %>">
    <CalendarDayTemplates>
        <telerik:DayTemplate ID="BlockedTemplate0" runat="server">
            <Content>
                <div>
                    {DayOfMonth}
                </div>
            </Content>
        </telerik:DayTemplate>
    </CalendarDayTemplates>
</telerik:RadCalendar>
<telerik:RadCalendar ID="ToDate"OnDayRender="Calendar_DayRender" runat="server"EnableAriaSupport="True" EnableShadows="True" AutoPostBack="True" EnableMultiSelect="False" ShowOtherMonthsDays="False"  RangeMinDate="<%# DateTime.Today %>"  SelectedDate="<%# DateTime.Today %>"  >
    <CalendarDayTemplates>
        <telerik:DayTemplate ID="BookedTemplate0" runat="server">
            <Content>
                <div>
                    {DayOfMonth}
                </div>
            </Content>
        </telerik:DayTemplate>
    </CalendarDayTemplates>
</telerik:RadCalendar>

C#:
protected void Page_Load(object sender, EventArgs e)
{
    var cal = FromDate;
    cal.SpecialDays.Clear();
    cal.SpecialDays.AddRange(BlockedDates(CalendarType.FromDate));
    var cal1 = ToDate;
    cal1.SpecialDays.Clear();
    cal1.SpecialDays.AddRange(BookedDates(CalendarType.ToDate));
}
private RadCalendarDay[] BlockedDates(CalendarType calendar)
{
    var version = (calendar == CalendarType.FromDate) ? 0 : 1;
    var template = "BlockedTemplate"+version;
    var cal = new List<RadCalendarDay>();
    var i = 0;
    var startDate = (calendar == CalendarType.ToDate) ? DateTime.Now.AddDays(-1) : DateTime.Now.AddDays(-2);
    var endDate = (calendar == CalendarType.FromDate) ? DateTime.Now.AddDays(-3) : DateTime.Now.AddDays(-4);
    for (var day = startDate; i<3; day = day.AddDays(1))
    {
        cal.Add(FormatDate(day, template));
        i++;
    }
    var days = cal.ToArray();
    return days;
}
private RadCalendarDay[] BookedDates(CalendarType calendar)
{
    var version = (calendar == CalendarType.ToDate) ? 0 : 1;
    var template = "BookedTemplate"+version;
    var cal = new List<RadCalendarDay>();
    var i = 0;
    var startDate = (calendar == CalendarType.ToDate) ? DateTime.Now.AddDays(-1) : DateTime.Now.AddDays(-2);
    var endDate = (calendar == CalendarType.FromDate) ? DateTime.Now.AddDays(-3) : DateTime.Now.AddDays(-4);
    for (var day = startDate; i < 3; day = day.AddDays(1))
    {
        cal.Add(FormatDate(day, template));
        i++;
    }
    var days = cal.ToArray();
    return days;
}
private RadCalendarDay FormatDate(DateTime day, string template)
{
    var calDay = new RadCalendarDay { Date = day, IsSelectable = false, IsDisabled = true };
    calDay.TemplateID = template;
    return calDay;
}
protected void Calendar_DayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)
{
   e.Cell.Text = e.Cell.Text.Replace("{DayOfMonth}", e.Day.Date.Day.ToString());
}
enum CalendarType
{
    FromDate, ToDate
}

CSS:
.rcDisabled
{
    background-color: darkorange;
    color: white;
    font-style: italic;
}

Thanks,
Shinu.
