SelectedItems collection not updated when items are removed

Allow users to resize the tiles. Possibly by dragging a left-mouse cursor on the edges of the tiles. This will give flexiblity beyond the 3 fixed size of minimized, maximized, and restored.

MapPath shape doesn't support data binding on the level of the MapPathFigure and MapPathSegment in WPF.
This feature is implemented in the new visualization engine -Visualization layer and the bindable wrappers - PathView, PathVigureView, PathSegementView , etc.

When the focus gets in RadRichTextBox, AutomationProperties.Name is not pronounced by screen readers (for example by Windows Narrator).

Workaround: the automation name could be set to the caret as demonstrated in the attached project.

Rendering issues occure when using Hierarchical virtualization mode and bring into view.
The issue is hit in both platforms - WPF and Silverlight. 

When you make the window very small in height and then revert it back to normal size the Pie connectors are gone.

When track changes are enabled deleted content is also taken into account when spellchecking.

Steps to reproduce:
- Type in a wrong word (e.g. thos). 

- Turn Track Changes on. 

- Select the o and replace it with i. 

Expected: The word is not considered wrong and underlined by the spellchecker.

Actual:  "thois" is spell checked and evaluated as wrong. 

'Decrement paragraph left indent' command can set negative left indent which makes bullets/numbering of a list clipped. Instead, it shouldn't be executed if the bullets/numbering would become invisible.

Workaround: Cancel the command in CommandExecuting event:

            this.radRichTextBox.CommandExecuting += (sender, e) =>
            {
                if (e.Command == this.radRichTextBox.Commands.DecrementParagraphLeftIndentCommand)
                {
                    if (this.radRichTextBox.Document.Selection.GetSelectedParagraphs().Any(p => p.IsInList && p.LeftIndent <= 24))
                    {
                        e.Cancel = true;
                    }
                }
            };

When a value is selected in the FontSize combo box using the arrows and Enter, the font size of the selected text is not updated. The same scenario is working as expected when using the font size combo box from the ribbon.

Chart - properties are not bound correctly when chart is in DataTemplate.

When inserting text (document fragment) next to a correctly spelled word they get both underlined as incorrect.

Check how the performance can be improved in this scenario. The StyleGallery is taking much time to load, the GetUsedCellRange method is called multiple times.

When hover over the fold of the right(left) page and around the fold, sometimes the opposite -left (right) page is changing its content (the next page is shown)

In a virtualized TreeView, after ExpandAll and scroll operations, there are gaps in the TreeViewPanel.

RadTreeViewItem.AutomationProperties.Name is not read correctly since version 2011.2

If you move an item from one level to another into the tree, the indent of the corresponding row won't get updated. This is reproducible only if the new parent of the moved item is expanded, while the operation is executed.

Usually, this can be reproduced by calling the ExpandHierarchyItem() for the new parent item method just after the moving of the original item.

To resolve this you can delay the expanding of the item. Note that the expanding is executed manually by calling the ExpandHierarchyItem() method. So, you can use a dispatcher with a lower DispatcherPriority to delay this.

Or alternatively, you can collapse the item before expanding it (using the CollapseHierarchyItem() method).

System.Windows.Media.Animation Warning is apparent during DragDrop in the TreeView in WPF.
