Telerik UI for Winforms

Release History

Q1 2010 SP2 (version 2010.1.10.504)

May 3, 2010


  • FIXED: An issue related to the AutoSize property value which is explicitly set to true in the constructor that causes the value to be serialized since the default value is different. The RadDateTimePicker now redefines the default value of this property and thus it is not serialized.
  • FIXED: An issue which prevented the calendar popup from acquiring its theme in case the RadDateTimePickerElement is used in another control's element hierarchy.


  • ADDED: A DoubleClick event for the RadTitleBarElement when in RadForm
  • FIXED: An issue in the RadFormBehavior which prevented the hover-state of the system buttons to be reset when the user releases the mouse outside the button or the form.
  • FIXED: An issue related with the MDI strip's icon which was displayed for each MDI child even though the MDI child has its ShowIcon property set to false.


  • Breaking change: RadMenuElement’s border has been removed from the Children collection of the FillPrimitive and now is a direct child of the RootElement.


  • ADDED: A SetItemVisibility method which allows the user to programmatically customize which items will be visible in the Quick Access Toolbar in the same way as it can be done over the overflow drop-down menu
  • FIXED: An issue which prevented the Application Menu's popup from being displayed correctly when the Ribbon is in RTL mode.
  • FIXED: An issue which caused keytips to be painted wrongly when Aero is enabled.

  • FIXED: Timeline View - you cannot scroll with the mouse wheel when you have a vertical scrollbar.
  • FIXED: Timeline View - invalid date when you open the Edit Appointment Dialog.

  • FIXED: Timeline View - deleting an appointment through the Edit Appointment Dialog would not hide it.
  • FIXED: Timeline View - Grouping by resources. Cannot navigate with the Right and Left keyboard arrows but this is possible with Next View from the Context Menu.
  • FIXED: Timeline View - right clicking on an appointment will bring an incorrect date in the Edit Appointment Dialog.
  • FIXED: Timeline View - Change the Time Scale through the API will have no effect on the Context Menu Time Scale.
  • FIXED: Timeline View - Next View would not work when the Time Scale is Week, Month or Year.
  • FIXED: Timeline View - Setting HeaderFormat will not apply to the column’s header.
  • FIXED: Timeline View - Setting TimeScale to Year would hide the horizontal scroll bar regardless of the fact that the difference between the RangeStartDate and RangeEndDate is several years.

  • ADDED: Base line support
  • FIXED: A memory leak in some controls which support UI virtualization.

  • ADDED: Brand new Windows7 theme.
  • IMPROVED: ControlDefault, Office 2007 Silver and Office 2007 Black themes (done with the new Visual Style Builder, so that they can be used as templates for creating new custom themes).
