Forbid typing a date earlier or later than a date if SelectableDateStart/SelectableDateEnd are set. Can be achieved by custom parsing.

Available in the 2016 Q1 Release: Implemented IsInputRestrictedToSelectableDates property in order to allow only selecting dates by input in the selectable range (when SelectableDateStart/SelectableDateEnd/BlackoutDates are used).

Create property that allows to open the dropdown on focus or change the implementation of the control so this can be achieved by code.

Added TodayButtonVisibility and TodayButtonContent properties for showing/hiding a button that selects current date and time - available in the 2016 Q1 Release.

Implement two-digit year parsing referred as €œThe 2029 Rule€ in the control like the parsing in Excel.
Examples:
In Excel: typing 1/1/70 returns 1/1/1970
In RadDatePicker: typing 1/1/70 returns 1/1/2070

When you set, for example, DisplayDateStart to 1/1/2011, DisplayDateEnd to 1/1/2012 and DateSelectionMode to Year, the RadDateTimePicker displays 2010 too. You can interact with the years within the range but not with the additional one. The way to avoid this activity is to set DisplayDateStart to 2/1/2011 (according to the given example) but the day corresponding to the 1/1/2011 will not be included.

Used to clear the Input field and set the SelectedValue to null, include dependency properties like ClearButtonVisibility and ClearButtonContent.

This is an issue with both a binding and a hard-set value

RadDateTimePicker ControlTemplate: PopupPlacementTarget in RadDropDownButton is not respected when FlowDirection of RadDateTimePicker is RTL. PopupWrapper issue.

RadDateTimePicker cannot parse datetime string when Windows date format is set to "Chinese (Traditional, Taiwan)".

If the InputMode of the DateTimePicker is set to TimePicker the DateTimeWatermarkContent states €œEnter Date€ and it should state €œEnter Time€.

For example if you have 12:00 selected and input 15:03 in the WatermarkTextbox- 12:00 item of the Clock is still selected

There should be a property like StringFormat, which can be set to something like "dd.MM". This is really common way across all wpf controls, and it's frustrating that currently it can be done only using code-behind. It's not MVVM friendly at all.

Change the time picker to a way that you can 'zoom' in on the time. In the same way as the decade>year>month zoom of the date part.

To be able to select times till minute or second precision

Currenly if you update the Value it will update the text as well preventing further digits to be entered in a meaningful way.

When StartTime = EndTime all hours are visable (12 am - 11pm)
Workaround:
Select EndTime in one hour interval from StartTime (10:00 - >10:01). In this situation only 10:00 will be visible

When FlowDirection is RTL, navigating in Calendar and Clock is inverted- pressing left arrow moves the selection to the right and vice versa.

When set DateSelectionMode="Month" and SelectionMode="CenturyView", the calendar in the dropdown starts from YearView instead of CenturyView
