It should be possible to specify whether the drop down should stretch to the width of the button or whether it should be left - right aligned. The same should apply for the vertical positioning when the popup appears left or right of the button.

There is a Dispatcher call without checking in the dispatcher call for NULL. This lead to NullReferenceException in huge production code.



Available in R3 2016 SP

MouseLeave event is never fired after we change the Them of the controls from a control located in the DropDownContent. Therefor the controls IsMouseOver property is true and looks like it is hovered.

The issue is not reproducible since R2 2016 SP1 version.

In that way it will be easy to set the popup animation to be slide, fade or scroll without setting a custom template.

Clicking on the RadSplitButton in XAML opens the designer unexpectedly

Available in LIB version: 2015.1.0309

DropDownButton's DropDownContent blinks when its template and its parent's ControlTemplate are changed at runtime

The issue can be reproduced with DatePicker inside of ComboBoxItem ItemTemplate.

Available in LIB Version 2016.3.1010, it will be also available in the 2016 R3 SP1.

Property values are inherited from the logical parent and not visual parent (as in SL). Thus ContentPresenter and ContentControls children doesn't get the new Foreground property. This can not be workarounded with VisualStates, but Triggers only

Reason for declination: WPF limitation

Add a visual representation for the IsDefault property like in Microsoft's button.

The native radio button supports validation. Implement validation for the RadRadioButton

Arg_COMException in some cases when used with RoutedUICommand

SplitButton throws a design time exception with implicit styles if you've included Diagrams.Extensions.xaml

Update the Buttons AutomationPeer to use the AutomationProperties attached properties.

As a workaround you can create a custom button control deriving from RadButton. That would allow you to create a custom AutomationPeer class that can return the AutmationProperties.Name value to a narrator application

An updated button that appears and acts like a hyperlink but is really a button with no borders but respects the enabled / disabled and all the visual states. 

 *  link should be disabled / grayed out if not enabled or if command guard is not enabled 
 *  could manage the 'visited' as a pressed (not interested in that for me, I just like the simple visual).
 *  the samples/demos homeview provides a nice example where the long text is highlighted and presents the hand icon. The re-styling is however 6 pages long and cumbersome to copy as it references other parts of the sample project (I tried)

*  3 Image properties (normal, hover, disabled)
 *  showBorder/flat true/false (Essentially making only the image appear as a button)
 *  if the 3 images are not set then the visual state manager should modify the image to appear disabled or hover with a highlight / mask overlay (or whatever the proper term is).

Close the DropDown popup when clicking on the DropDownContent in DropDownButton.

Available in R3 2016 Official Release.

When a RadMenu/RadContextMenu is used as DropDownContent of a SplitButton/DropDownButton, the DropDownContent  cannot be closed after sub menu items are displayed

DropDownButton is leaking.

Implement functionality similar to http://demos.telerik.com/aspnet-ajax/button/examples/togglebutton/defaultcs.aspx
