Missing StaticResource error (ScrollBarStyle) is thrown when using implicit styles and merging the Telerik.Windows.Controls.RichTextBoxUI.xaml file.

The tool does not found issues in a Silverlight project

The current workaround is to edit the control template of the control and set the MinWidth of the PART_ListBox element:

                   <Popup x:Name="PART_Popup">
						<Grid x:Name="PopupRoot">
							<telerik:RadListBox x:Name="PART_ListBox"
												 MinWidth="{TemplateBinding MinDropDownWidth}"
												MaxHeight="{TemplateBinding MaxDropDownHeight}"
                            ItemsSource="{TemplateBinding FilteredItems}"
                            ItemTemplate="{TemplateBinding DropDownItemTemplate}"
                            FontFamily="{TemplateBinding FontFamily}"
                            FontSize="{TemplateBinding FontSize}"/>
							<Border
                            Background="{Binding Background, ElementName=PART_ListBox}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="1"
                            Width="{Binding ElementName=PART_ListBox, Path=Width}"
                            Visibility="{Binding ElementName=PART_NoResultsContentPresenter, Path=Visibility}">
								<ContentPresenter x:Name="PART_NoResultsContentPresenter"
                                MinWidth="{TemplateBinding MinDropDownWidth}"
                                MaxHeight="{TemplateBinding MaxDropDownHeight}"
                                Content="{TemplateBinding NoResultsContent}"
                                ContentTemplate="{TemplateBinding NoResultsContentTemplate}"
                                Visibility="Collapsed"
                                Margin="5 4"/>
							</Border>
						</Grid>
                   </Popup>

Available in LIB version 2018.1.205, it will be also available in the R1 2018 SP2 Release.

ExtMap Files (for Application Caching) are missing from NuGet Separate Packages although they are included in the full package.  Please include these.

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.

When RowStyle is applied to RadGridView, AlwaysVisibleRow part disappears after adding a new item.  The problem occurs only when the style is applied explicitly. 

The RibbonWindow Title glow effect is remove when the theme is changed dinamically

The RibbonView TabStrip ScrollViewer is displayed unexpectedly when there are inactive ContextualGroups.

When the groups of a RadRibbonTab are collapsible the scroll is shown just before the groups collapses.

When the RadRibbonView ItemsSource is populated with RadRibbonTabs and one of the tab items IsSelected property is set to True that item no longer can be selected.

With 2016 Q1 version, a static TouchManager class was introduced allowing for handling touch gestures and defining custom gestures.

It will be nice to expose public API to allow custom touch handling.

Completed:
With 2016 Q1 version, a static TouchManager has been introduced allowing handling of touch events, gestures, and adding custom touch gestures.

Will be available in Q1 2016 Release.

This will preserve the exported image quality. Currently the only option to achieve this is through the EncodedImageData class. However, using this approach is not easy because the user have to know the width, height, color space and filters of the image.

Spellchecking specific text throws NullReferenceException. Specific example would be '..)aaa' text.

Since the Q12015 update, if you add a RadCalendar to a project, and try to use the No XAML binaries with the VisualStudio2013 or Office2013 themes, the designer will crash.
