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

Available in R3 2016 Official Release.

DropDownButton is leaking.

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

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

*  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).

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

Arg_COMException in some cases when used with RoutedUICommand

Should work the same as the RadContextMenu. 
Also add support for setting effect (DropShadow... ) to the Dropdown itself.

Add Closing event.

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

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

NullReferenceException is thrown if you set the IsChecked property of the RadToggleSwitchButton before the button is added to the visual tree. This happens only when the switch animation is disabled.

To work this around, you can set the AnimationManager.IsAnimationEnabled property of the button to True initially. And then set it back to False on Loaded of the button.

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)

Make the image inside the buttons to be aware of the FlowDirection.

When IsThreeState property is true, after each click values of IsChecked property cycle like this: null -> false -> true. I would like to reverse this order to null -> true -> false in some cases and a property controlling that order would be a great help.

A StackOverflowException occurs when you press a RadDropDownButton placed into the DropDownContent of another RadDropButton.

To work this around, subscribe for the LostMouseCapture event of the parent drop down button and handle it.

private void DropDownButton_LostMouseCapture(object sender, MouseEventArgs e)
{
      e.Handled = true;
}

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.

The UI freezes if the DropDownContent of RadDropDownButton has a native Run element and the CloseOnPopupMouseLeftButtonUp property is set to True.

If you have a tooltip on a button and focus the button before hovering it, the tooltip is not shown
