When using Two-way binding and the RadListBoxSelectedItemsBehavior for RadListBox's SelectedItems, the items are not re-added to the Visual Tree after the theme is changed at runtime. 

when only one data ,the Chart3D Bar drawing will exceed the floor,looking the attachments pls.

I know the Transitioncontrol  have the MotionBlurredZoomTransition, the effect is better for image ,but not UI content,especially when the UI use the simple color,the MotionBlurredZoomTransition effect is weak,I find the RadCalendar control with the cool zoom animation,How to realize?
     the other question:How to realize the book turning animation with the Transitioncontrol  ?

with windows10/2k DPI/14 inch screen ,when show the gridview gridline,the line is different.
     the other things,when the tabitem is selected,the dropdownmenu can't mark the selected item.
   look the attach files!

Basing on the "{StaticResource FilterControlStyle}" would cause an InvalidArgumentException, if the types would mismatch. 
If you are to base on a custom style on the default style of either of those controls, you can do it by type reference - e.g. BasedOn="{StaticResource {x:Type telerik:FilteringControl}}"

I want to have opportunity to disable RadExpander header because I want to programmatically expand or collapse RadExpander control.

You have, for example rectangle which is in ContentControl in XAML, next to FluidC.C.

FluidContentControl is in small state. Ona  button click SmallContent is assigned to the Rectangle.

This leads to the exception stated that rectangle is already a logical child of another element.

User can set AutoCalculateBounds to True by the following way:

 public class CustomClusterGenerator : DefaultClusterGenerator
    {
        public override ClusterData CreateCluster(Location center, object item)
        {
            var clusterData = base.CreateCluster(center, item);
            clusterData.AutoCalculateBounds = true;
            return clusterData;
        }
    }

  this.VisualizationLayer1.ClusterGenerator = new CustomClusterGenerator();

When clustering 4 points:

ObservableCollection<DataItem> items = new ObservableCollection<DataItem>()
            {
                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(20, 30) },
                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(20, 34) },

                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(22, 32) },
                new DataItem() {MapLocation = new Telerik.Windows.Controls.Map.Location(18, 32) },
            };

            this.VisualizationLayer1.ItemsSource = items;

EXPECTED:  ClusterData's Bounds must  be:

WEST: 30 and EAST: 34.

Actual Values are 30 and 30 (29.9999 and 30).

looking the attach file,when resize the second gridview's column moving back and forth when at first run the sample,the after columns flicker and the width grow and lessen.and when resize the third column,the 'unit price' column will become the min width.
but when test the microsoft's datagrid,it is good,the any other column width's change is gentle.

Hello,

I am using DateTimePicker with JAWS.  Here are the issue I ran into:
1. JAWS reads out watermark 3 times
2. JAWS reads out date and time where there is only date populate and dateformat is set for shortdate.  For example, date is "04/12/2018".  JAWS reads "04/12/2018 00:00:00"
3. Once the date is populated and date field got focus, it will read out date and time at least 2 times.

I work on project that required it to compliance with government section 508. This issue will not allow me to use Telerik's datepicker.  Please fix this.

look the attach file.

When both horizontal and vertical ScrollBars are visible in Fluent theme, the "BottomHandle" RepeatButton cannot be pressed as it is overlapped by the horizontal ScrollBar on MouseOver. 

Default behavior will be changed and the scrollbars will be reordered in the ScrollViewer ControlTemplate so on MouseOver the current ScrollBar will have higher Canvas.ZIndex. 

Fix available in R2 2018 SP1 version.

     if the pie chart area's size is auto,when adjust the area's  vertical size,the pie's radius  will change in order to fit the label display,it is ok,but when adjust the area's horizontal size,the pie's radius don't  change,looking the attachment file,the label move above the pie.

I would like to do a Backstage design without writing code, the syntax of XAML is confusing and I do not understand it well, besides being slow, the development of software at design time is always much faster.
