HeaderWidth and HeaderHeight properties should be made RadProperties and should be declared at RadCalendarElement. This will allow our users to set these properties in theme.
When you click on a Navigation Button with the mouse in RadCalendar and hold the button down, then it scrolls automatically to the next/previous views very fast. Same behavior should be supported by the Fast Navigation Buttons.
To reproduce: - Add RadCalendar to a blank form and set its AllowMultipleSelect property to true. - Select a date and deselect it right after that. You will notice that the background is not changed. - The cell is actually deselected but it appears as selected since it is the focused cell and the styles are equal. Workaround: Change the style for the focused state, which will allow the user to distinguish between focused and selected cells.
Currently, you can use reflection in order to access the properties of the fast navigation popup. Workaround: this.radCalendar1.HeaderNavigationMode = Telerik.WinControls.UI.HeaderNavigationMode.Popup; CalendarNavigationElement a = this.radCalendar1.CalendarElement.CalendarNavigationElement; FieldInfo fi = typeof(CalendarNavigationElement).GetField("dropDown", BindingFlags.NonPublic | BindingFlags.Instance); RadDateTimePickerDropDown dropDown = (RadDateTimePickerDropDown)fi.GetValue(a); dropDown.PopupOpening += new RadPopupOpeningEventHandler(dropDown_PopupOpening);
