The placeholder disappears if it's in a RadPane and you close another RadPane

Add support for opening media files from client's local machines. At the moment an exception is thrown.

Due to the radically decreased interest in Silverlight the XAML team decided to considerably reduce the efforts invested in any new features or new components in the UI for Silverlight offering. Hence this request will not be addressed and is marked as declined.

When the user navigates in a page displayed in the placeholder and then it is removed and added in the visual tree (when in RadDocking for example) the original SourceUrl is displayed while ideally this should be the page that the user has navigated to.
Update: You can fix this by setting the HTMLPlaceholder's KeepContentInMemory property to True.

When IsTabStop = False the focus is going through :

 *  RadAutoCompleteBox
 *  RadComboBox (when IsEditable is set to True)
 *  RadNumericUpDown
 *  RadMaskedTextInput
 *  RadDatePicker
 *  RadDateTimePicker

Available in the R3 2016 Release.

For RadAutoCompletebox, RadComboBox, RadDateTimePicker and RadNumericUpDown, the TabNavigationExtensions.IsTabStop attached property should be used to indicate whether the control is included in the tab navigation cycle.

For RadMaskedTextInput, MaskedInputExtensions.IsEditorTabStop attached property should be used.

The fix will be available in our official release 2015 Q2.

This only happens in IE8.  IE9, Chrome, FF3 and FF4 all work okay.  As soon as the componenet is set to visible the scrollbar appears because something has been added to the body html.  The suggested workaround to have the body style overflow set to hidden

When using custom DataTemplates for the timeline items, the selection feature does not work,
 
The workaround for this problem is to use a custom control in the DataTemplate that inherits TimelineItemControlBase. You can use the ControlTemplate of this custom control to define the look and feel of the timeline items as well as their visual states. The approach is demonstrated in our First Look demo - http://demos.telerik.com/silverlight/#Timeline/FirstLook .

Fix available in LIB Version 2016.2.516.
