A new theme which will follow the look and feel of Windows 10 OS and the subordinate Office 2016 Microsoft products. There should be two versions - a normal layout and touch-optimized one.

Available in the 2016 R3 Release.

Some styles are duplicated in VisualStudio2013 theme. For example:

For example, RadButtonStyle is located in:
-Telerik.Windows.Controls.Data.xaml
-Telerik.Windows.Controls.Navigation.xaml
-Telerik.Windows.Controls.Input.xaml

This creates conflicts when I try to change default style of a RadButton because other styles are applied instead.

Reason for declination: 
We understand that having duplicate styles can be annoying for our customers. However in Silverlight the base style in a resource dictionary cannot be omitted. As for WPF, it is possible but will lead to exceptions if there is a missing resource dictionary or wrong order of the merged dictionaries which would be unwanted change for our customers. 

That is why we suggest our customers to merge their custom styles after Telerik default ones thus maintaining and upgrading is easier. Another option (in WPF) is using a custom build of our themes where all unwanted duplicates are removed. If you choose the second, you will need to remove button's style from all XAML files except the Telerik.Windows.Controls.xaml one and edit it there.

If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.

Currently RadPdfProcessing imports Contents only from stream. In some documents Contents property may be PdfArray.

Since the next version of the Office Microsoft products after Office 2013 is Office 2016, we created a new feature request in our feedback portal:

When encryption is enabled, the streams inside the PDF document are encrypted individually. If the encrypted result contains '{' or '}' symbols, FormatException ("Input string was not in a correct format.") is thrown.

A selection in RadListBox, RadColorPaletteVIew, RadTreeView. RadGridView etc. cannot be made with touch gestures when the control is inside a ScrollViewer.


Reason for declination:
This is not a bug in the touch logic of the controls. The selection does not work because the manipulations of the ScrollViewer are enabled and the scroller captures the touch and marks the touch events as handled, leaving the ScrollViewer the only element to receive touch events. There are at least two possible solutions for this.

1.If you have access to the ScrollViewer, you can set attached TouchManager.ScrollViewerSwipeMode for the ScrollViewer to Self.

<ScrollViewer telerik:TouchManager.ScrollViewerSwipeMode="Self" />

2. If you do not have access to the ScrollViewer, you can use a combination of two attached properties, for the elements inside the scroller. The two properties are two of the attached TouchManager properties - TouchMode and ScrollViewerSwipeMode.

<ScrollViewer>

   ...

      <telerik:RadCartesianChart telerik:TouchManager.TouchMode="Locked" telerik:TouchManager.ScrollViewerSwipeMode="Parent" />

In case table cell doesn't have background directly applied it should inherit the background of its parent table.

At this point only styling through CSS is supported. The below code does not align the paragraph to the center

            string import = "<html><body><p align=\"center\">centered??</p></body></html>";
            RadFlowDocument document = provider.Import(import);

Add API to get the list of ranges to which a defined name refers.

Example:
List<CellRange> ranges = workbook.Names["definedName"].Ranges;
CellSelection selection = worksheet.Cells[ranges];

While eventToCommand works it is verbose and somewhat of a hack.  I would really to see better MVVM support by having a command property on all of the controls for all events

The layout grid in RadDiagram is a little lacking and it would be a lot more powerful if it supported a similar layout grid to Adobe Illustrator. The features of interest are:

Grid Subdivisions - You specify the gridsize as currently, say 8px, but then you can also specify a number of subdivisions, say 2. This will split the 8x8px grid cell into four 4x4px grid cells, and allow snapping to the 4x4px grid cells.

Grid to back/front - allow the grid to be overlaid on top or behind the diagram so that you can optionally see the grid all the time.

See attached diagram.

Thanks

The mentioned cells can be controlled with attached properties of the BackgroundGrid and BackgroundPageGrid.

To move these grids on top of the shapes you need to edit the default template of the RadDiagram and reorder the Grids in XAML.
