In RadGanttView, the drag reorder visual element position indicators ('Before', 'After', and 'Inside') are not translated according to the application's UI culture settings (e.g., German), remaining displayed in English because they are hardcoded in the element's template.

To work this around, create a custom DragReorderTemplate and apply it via the CueTemplateSelector of GanttDragResizeVisualCue. This can be applied via an implicit style defined in App.xaml.

 <Style TargetType="telerik:GanttDragResizeVisualCue">
     <Setter Property="CueTemplateSelector">
         <Setter.Value>
             <telerik:GanttDragVisualCueContentTemplateSelector DragTemplate="{StaticResource GanttDragResizeVisualCueTemplate}"
                                                         ResizeTemplate="{StaticResource GanttDragResizeVisualCueTemplate}"
                                                         CreateDependencyTemplate="{StaticResource GanttCreateDependencyTemplate}"
                                                         DragReorderTemplate="{StaticResource CustomGanttDragReorderTemplate}" />
         </Setter.Value>
     </Setter>
 </Style>

When adding new tasks the control does not update his ExtentHeight and ExtentWidth.

Available in LIB version 2015.3.1123, it will be also available in the 2016 Q1 release.

Make the default behavior of the auto scrolling which is trigger by selection of a task in the GridView part of the control customizable. 

The current default built-in behavior is:
* If you select a row (task) in the GridView part which has its event container currently not visible is auto scrolled into to the view to the default (left) position in the TimeRuler

When the Window OS DPI setting is set above 100% resizing the grid portion's columns with their resizer controls leads to unresponsive UI and possible application crash.

Add the possibility of TimeRuler's TickIntervals to respect the CurrentUICulture's time format.

The selection shown in the exported image is wrong in some cases. This is reproducible when you select multiple items (more than 2).

To work this around you can clear the selection before the export and then re-select the items. To do this you can use the SelectedItems collection of the RadGanttView control.

This reproduces with recurring tasks.
