We need to produce a pdf copy of an html(aspx) page and stream it to the client. Many of components in your asp.net library uses Javascript to create html. 
When you create the support for pdf we would like to use your library to do this job.
At the moment we are using another third party library to do this since it also supports Javascript.

Hello,
Like a lot of companies we have multiple client side interfaces of a single application and have to create similar UI in multiple platforms.
For example I had to create a chart in both WPF and ASP.NET AJAX today.
The problem I have with the Telerik controls is that there are absolutely no standardization or consistency between platforms.
Why in the name of all-things-good-in-this-world are axes in WPF and ASP.NET AJAX and ASP MVC and Windows Universal Apps not all called the same thing?
It would be very simple to use interfaces to create some consistency between platforms.
Even better would be if Model Views are shared across platforms in a portable library:

Regards,
Douw
PS. I could not find a feedback portal for all platforms, so have to log this multiple times.

Allow customizing provider for sending xmla request and response from/to SSAS. Currently it's can only be done with System.Net.WebClient and msmdpump.dll (IIS)...

My RadTreeView is bound to VirtualQueryableCollectionView. Changes on Filter and Sort Descriptors works fine but calling to VirtualQueryableCollectionView.Refresh() method throws a NullReferenceException with the following stacktrace:

When the RadRibbonSplitButton fires the command everything works fine.

When the RadMenuItem inside the RadRibbonSplitButton.DropDownContent fires the same command, the "this.Cursor = Cursors.Wait;" inside the method has no effect.
The Cursor doesn't change.

See the attached sample application

Decline Reason: This behavior is expected and it comes from the WPF native Popup element which hosts the button's DropDownContent. Basically, when the split button is clicked and the Window Cursor is changed, the mouse is over the window before the application freezes and you can see that it is changed. On the other hand due its specifics the Popup is not placed directly in the Window (it is rendered into a separate visual tree) and when the Window's cursor is changed, you won't see it because the mouse is not over the Window. So, the application freezes before the mouse gets over the window. You can resolve this by setting the Popup Cursor property or the static Mouse.OverrideCursor property.

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.

First column of the pivotgrid has width based on the header (see attached screenshot). It's obvious that the header should span between columns.

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:
http://docs.telerik.com/devtools/wpf/controls/raddiagram/overview.html

The themes are great. But it's difficult to create a new one from scratch. It'd be great if there was a Theme Creator/Editor that allowed a designer to start from scratch, or create a new theme based on an existing one. The UI would allow the designer to preview the new theme in real time against live theme-supporting Telerik controls and see the results. 

i would like to change background color when click in (Day,Month,Week,Timeline).

Based on your new radZIPLibrary it would be great if you could implement a universal, mvvm compatible backup library.

It should provide support for multiple spanning medias, catalogs, discarding old backups after some time, encryption and backup of file ACL and registry data.

This would be a perfect addon for your Diagram, Spredsheet and RichText libraries!

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.
