Hello,

Thank you for the question.

Please note that before adding the SpecialDays of the second user you should clear the SpecialDays collection of the first user. I am attaching a sample project which behaves correctly on my side. If you continue experiencing the issue even after you clear the SpecialDays collection, please send me a sample project which demonstrates the issue. You can send the project in the support ticket that you have opened. This will allow me to help you further.

Hi ,
tanks for the answer.

Ok, what i am doing is this

foreach (DataRow dr in dt.Rows)

{

//rCal.SpecialDays.Remove(new RadCalendarDay(Convert.ToDateTime(dr["data"]).Date));

var rlbi = new RadListBoxItem(Convert.ToDateTime(dr["data"]).Date.ToShortDateString());

rLBDates.Items.Add(rlbi);

lbl = new RadLabel

{

Text = Convert.ToDateTime(dr["data"]).Day.ToString(),

TextAlignment = ContentAlignment.MiddleCenter,

BackColor = Color.ForestGreen,

ForeColor = Color.DarkViolet

};

lbl.BringToFront();

hostItem = new RadHostItem(lbl)

{

ToolTipText =

dr["idTecnico"] + "-" + dr["tecnicoNome"] + "-" + dr["estado"] + " ",

BackColor = Color.ForestGreen,

ForeColor = Color.DarkViolet

};

hostItem.BringToFront();

rcd = new RadCalendarDay(dc)

{

TemplateItem = hostItem,

Date = Convert.ToDateTime(dr["data"].ToString()),

ToolTip = "dsdsadas",

};

dc.Add(rcd);

}
so when i make rCal.SpecialDays.clear() it does nothing...

Can you help me please.

Tanks in advanced,

Best regards,

Hi Helder,

You can find the answer to your question in the support ticket that you have opened.

In case our community is interested in the topic, here is my response in the ticket:
I am still not able to reproduce the describe issue. Please refer to the updated sample project attached to my current reply. Since I am not able to reproduce the issue in a sample project it seems that there is something special in your project which makes the issue appear. Please send me this project as it will allow me to investigate your case in details and provide you with further assistance.

Hi.
I find that if i have more than 90 special days put into Radcalendar.it takes more than 7 seconds to load the redcalendar.
It is too slow.
Do you have any idea about this?
thanks in advance!

I am using the Telerik controls from Winforms_2013_1_220. No matter what I do I cannot get the special days tooltip to show up or work. I downloaded the 'RadCalSpecialDays' project and the tooltip did not work there either. Is this broken in the version I am using? Or am I doing something wrong.

From the getting started calendar video it looks as though I should be able to add a RadCalender, add a special day, add a tooltip (in the video they used July 4, Independence Day). When I run the project the tooltip should work, but it doesn't. I have AllowTooltips and ShowItemTooltips set to True.

In code I have also tried;

Dim myDay As DateTime = "2013-01-15" calMyEvents.SpecialDays.Add(New RadCalendarDay(New DateTime(myDay.Year, myDay.Month, myDay.Day, 0, 0, 0))) calMyEvents.SpecialDays(myDay).ToolTip = "My Tooltip" calMyEvents.FocusedDate = myDay

Hi Brendan,

Can you please also set the AutoToolTip property of the visual element as follows:

Private Sub RadCalendar1_ElementRender(sender As Object, e As Telerik.WinControls.UI.RenderElementEventArgs) Handles RadCalendar1.ElementRender

e.Element.AutoToolTip = True

End Sub

Let me know how this works for you.

All the best,
Stefan

Hi Stefan. When I set "e.Element.AutoToolTip = True", it shows a tooltip for the day number, not the tooltip I set. For example, if I hover over March 15, the tooltip is "15". In fact every day now has it's own tooltip.

Hi Brendan,

Please excuse me for the introduced confusion. It seems that this is an issue with this and it is already logged in our Public Issue Tracking System. Feel free to add your vote for it here: http://www.telerik.com/support/pits.aspx#/details/Issue=12988.

For the time being you can use the ToolTipText needed event instead:

Private Sub RadCalendar1_ToolTipTextNeeded(sender As Object, e As Telerik.WinControls.ToolTipTextNeededEventArgs) Handles RadCalendar1.ToolTipTextNeeded

    Dim cell As CalendarCellElement = TryCast(sender, CalendarCellElement)

    If cell IsNot Nothing Then

        If cell.SpecialDay = True Then

            e.ToolTipText = "Special day"

        Else

            e.ToolTipText = "Normal day"

        End If

    End If

End Sub

I hope this helps.

Kind regards,
Stefan

Thanks Stefan, but I don't think that is going to work. I need to load several dates from a db for specific users and would have this type of info;
02/15/2012, "Payment Due"
03/22/2012, "Reset Rates"
03/05/2012, "Business Holiday"
etc. for many records.

I need to add the tooltip when I add the date to the calendar as I'm not sure how I could 'know' what the tooltip during the Tooltip_Needed event? I don't want to re-query the database every time I need a tooltip.

If there was a .tag for the special day I could add the Tooltip there and call it later on the Tooltip_needed event, but I don't see anything like that.

Unless there are other suggestions?

Hello Brendan,

I can suggest using a Hashtable to store your tooltips instead of a Tag. When you populate the SpecialDays, populate the hashtable and then use it in the ToolTipTextNeeded event:

Imports Telerik.WinControls.UI

Public Class Form1

    Dim tooltips As Hashtable = New Hashtable

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        Dim myDay As DateTime = "2013-04-15"

        RadCalendar1.SpecialDays.Add(New RadCalendarDay(New DateTime(myDay.Year, myDay.Month, myDay.Day, 0, 0, 0)))

        RadCalendar1.SpecialDays(myDay).ToolTip = "My Tooltip"

        tooltips.Add(myDay, "tooltip for " + myDay.ToString())

        RadCalendar1.FocusedDate = myDay

    End Sub

    Private Sub RadCalendar1_ToolTipTextNeeded(sender As Object, e As Telerik.WinControls.ToolTipTextNeededEventArgs) Handles RadCalendar1.ToolTipTextNeeded

        Dim cell As CalendarCellElement = TryCast(sender, CalendarCellElement)

        If cell IsNot Nothing Then

            If tooltips.Contains(cell.Date) Then

                Dim tooltip As String = CStr(tooltips(cell.Date))

                e.ToolTipText = tooltip

            End If

        End If

    End Sub

End Class

Let me know how this works for you.

All the best,
Stefan
