Support the nesting of a RadDocking control in RadPane or other RadDocking control.

Add new control to the suite: Wizard control.

Available in the 2016 R3 Release.

Please take a look at our help article for more information:
http://docs.telerik.com/devtools/wpf/controls/radpasswordbox/overview

We would like to have the ability to merge cells vertically with same content. Consider to do the same horizontally.

Add SelectedItemsSource property which can be bound to a collection in the view model. In this case when the RadListBox is in Multiple/Extender mode, the selection can be manipulate from the ViewModel.

The control should be more customized than normal status bar control for WPF.

The XAML team has recently reviewed this issue and will not be addressing it as with Q1 2014 we introduced theme support for the System.Windows.StatusBar component. This means that you can use the native component within a Telerik powered application and at the same time have a seamless look and feel.  

You can check our Theming SDK demo under MSControls by downloading our SDK browser for WPF on the following page: http://demos.telerik.com/xaml-sdkbrowser/

If you want to share additional requirements about this control please contact us through the support ticketing system with details and a reference to this item.

Allow developers to add their own functions to the list of available functions in the RadExpressionEditor and then pass these functions to the LINQ runtime when the expression tree is built. Add support for custom Categories as well.

Scheduled for: 
The feature will be available in R1 2019, scheduled for the mid of January 2019. 

Add new control to the suite: TimeSpan Picker

Implement support for content controls (a.k.a. Structured document tags), which will allow inserting editing controls in the document:

- Rich Text
- Plain Text
- Check Box
- Combo Box
- Drop-down list
- Date picker

Do not confuse this feature with form fields support (see http://feedback.telerik.com/Project/143/Feedback/Details/146869 ).

In the following scenario:

    Floating Pane's size has been changed.
    The layout has been saved.
    The layout has been loaded.
    The Pane has been docked.
    Making the Pane floating should retain the custom size from point 1.

Ability to grouped the appointments in hierarchical groups.

Implement two-dimensional Radar / Polar series type for WPF / Silverlight.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView.

Implement DragAndDrop in terms of allowing a reordering of the ToolBars in the ToolBarTray and moving toolbars from one tray to another.

Is there a way to get the map to continuously scroll without seeing the gray area? As an example, GoogleMaps, MapQuest, etc.. let you scroll left to right without getting to the "end of the world", it just continues to wrap around. I'm trying to avoid seeing the gray when I scroll too far left or right.

The feature for WPF will be available with R3 2016 in September.

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Note: Do not confuse with Text/Rich Text content controls (https://feedback.telerik.com/Project/143/Feedback/Details/113730 ).

Would it be possible to add a new theme that accurately tracks the Google Material Design guidelines?  (http://www.google.com/design/spec/material-design/introduction.html).

Implement import of documents containing Type 3 fonts.

Coming from RadControls for WinForms I did miss this control.
It didn't take me long to create my own alert controls, but it would be nicer to have them styled and behave like all other telerik controls.

Create an Office2010 theme.

You should be able to prevent the horizontal/vertical overlapping of routed connections . This way the connections should be easier to differentiate.

To better differentiate connections, users might:

            --- use labels on the connections

            --- use bezier connections

            --- use different colors for different connections

            --- use more custom connectors and attach the connections to not used connectors

            -- use AStartRouter instead of the default one (Grid Router)
