    I am a newby with RadControls.
    I am trying to use tooltips for the RadCalendar control in a simple Test-Form, the Properties RadCalendar.AllowTooltips and RadCalendar.ShowItemToolTips are true.

    I get tooltips, using one of the following feature: 
    • private void radCalendar1_ElementRender(object sender, Telerik.WinControls.UI.RenderElementEventArgs e) 
      {
        e.Element.TooltipText = "A Tooltip";
      }
      •  
    • private void radCalendar2_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e) 
      { 
        e.TooltipText = "A Tooltip";
      }
      
    
    

    
But I don't get the following  "default" tooltips:

      
    
    • NavigationNextTooltip,...
      • 
    
    • SpecialDay-Tooltips by setting "SpecialDays.ToolTip" in VS Designer
      •

    Hello Friedhelm,
    

    
Thank you for writing.
    

    
To enable tooltips in RadCalendar you should use the ToolTIpTextNeeded event of the control. To allow the tooltips to show, the ShowItemToolTips should be true (which is the default setting). Here is an example how to handle it for the available elements in RadCalendar:
    

    

    void radCalendar1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
    

    {
    

        CalendarNavigationElement navElement = sender as CalendarNavigationElement;
    

        if (navElement != null)
    

        {
    

            e.ToolTipText = navElement.Text;
    

        }
    

     
    

        CalendarCellElement cell = sender as CalendarCellElement;
    

        if (cell != null)
    

        {
    

            if (cell.SpecialDay)
    

            {
    

                e.ToolTipText = "Special day: " + cell.Date.ToString();
    

            }
    

            else
    

            {
    

                e.ToolTipText = cell.Date.ToString();
    

            }
    

        }
    

     
    

        RadButtonElement btn = sender as RadButtonElement;
    

        if (btn != null)
    

        {
    

            switch (btn.Class)
    

            {
    

                case "prevButton":
    

                    e.ToolTipText = "Previous button";
    

                    break;
    

                case "nextButton":
    

                    e.ToolTipText = "Next button";
    

                    break;
    

                case "fastForwardButton":
    

                    e.ToolTipText = "Fast forward button";
    

                    break;
    

                case "fastBackwardButton":
    

                    e.ToolTipText = "Fast backward button";
    

                    break;
    

     
    

                default:
    

                    break;
    

            }
    

        }
    

    }
    

    

    
I hope this helps. Let us know if you have any other questions.

    Ok, I know this.
    
But what's the purpose of the properties RadCalendar.SpecialDays[x].ToolTip, RadCalendar.NavigationNextToolTip, RadCalendar.NavigationPrevToolTip?
    

    
For example the description of NavigationNextToolTip is:
    
Gets or sets the text displayed as a tooltip for the next month navigation control.
    

    
Best regards
    
Friedhelm

    Hello Friedhelm,
    

    
Thank you for writing back.
    

    
The purpose of these proprties is to allow you to set the ToolTipText property for the desired elements and later in the event previously mentioned you can access the value of this property and assign it accordingly. This way you can store custom text as tooltips on per element basis. I will quote for example the source code related to these properties:

    

    this.prevButton.ToolTipText = this.Calendar.NavigationPrevToolTip;
    

    

    I hope this helps.
    
All the best,
