Hi!

I really enjoy the features of your products. However, the update mechanism is a complete pain in the ... behind. There are so many updates. Every time we have to run the update wizard, every time this breaks something, especially when working in teams. Updating via the Telerik Control Panel is tedious and time consuming.

Please make this process better. The simplest thing would be to just use NuGet with a VS plugin that validates if a license is present.

I spend hours and hours debugging stuff like this, and I am doing so right now again. The upgrade wizard broke some dependencies and now I have to check EVERY VIEW IN MY APPLICATION to check if there will be runtime errors with AssemblyNotFound "Telerik.Whatever". 

Please, please, I can't take it anymore!

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.

A data form control that allows the users to rearrange the fields using drag-drop and then save the layout. This control would be used in information systems where the admin users should be able to create custom forms for the regular users.

LayoutControl is now officially available since R3 2016 Release.

A control that allows you to generate complex layouts.

Available since R3 2016 Official Release.

Add new control to the suite: TimeSpan Picker

Available in LIB version: 2016.2.725

When set MinLines and MaxLines to a TextBox styled with and theme different from Expression Dark, entering text in the TextBox results in an unexpected behavior of the TextBox Height.

Fix available in LIB Version 2016.2.627.

CheckBox enters the incorrect state on press and hold in VisualStudio2013 theme. Once it's checked, the check mark disappears on press and hold. 

Available in LIB version 2016.2.525, it will be also available in the 2016 R2 SP1 release.

Features to support:
- Text blocks with basic formatting, preferably draggable, and preferably with customizable borders/backgrounds.
- Basic drawing functionality such as pencil, brush, lines, circles, rectangles etc. Of course with color selection for lines and fill. 
- Line thickness selection. 
- Being able to move the objects around the board would be nice.
- Connecting objects with some sort of connector lines, pretty much like the map structure in SketchFlow, if you are familiar with that. 
- Some basic shapes, such as arrows and icons that can be dragged/dropped on to the board.
- Support for uploading images and dragging them onto the stage. 
- XAML export (necessary for saving a drawing)
- Printing
- Magic marker/highlight functionality
- Collaboration support. This is a big one, and I am not sure how it should be implemented. Full collaboration functionality out of the box would require a service running duplex WCF or something similar. Alternatively, perhaps Telerik could provide us customers with an API and some sample code. Then we could handle the back-end stuff ourselves.

Our XAML team has recently reviewed the status of this feature request. Since most of this requirements are covered by our RadDiagram Control / Framework we are changing the status to Completed.
Please follow RadDiagram documentation:

Is there any way to easily see the comprehensive differences between two versions? We have an application that is still on version 2012.1.326 that we are intending to upgrade to the latest, but there is no simple way to tell what breaking changes might have been made. Our customer is asking us what features may no longer work as expected, but it would be practically impossible to go through every single set of release notes because there are so many between now and then. A simple replacement to "see what happens" isn't really feasible either because the application is so large and some of it was written by a third party.

We’ve introduced the Telerik API Analyzer tool that helps determine the problematic areas when upgrading a WPF, WinForms or ASP.NET Web-Forms application to a newer version of our controls. You can read more about the tool in this blog post: http://www.telerik.com/blogs/api-analyzer-helps-upgrading-telerik-projects.
