This theme is available in WPF suite. We have the Light and Dark variations as well. 

Poor support for custom DPI scaling in Windows 7 - Windows 10.
There no null checking, and there is dirty hacks:

CASE 1: RadPageViewElement
 public override void DpiScaleChanged(SizeF scaleFactor)
        {
            base.DpiScaleChanged(scaleFactor);

            if (this.Owner != null && this.Owner.Pages.Count > 1)
            {
                this.Owner.SuspendEvents();

                if (this.Owner.SelectedPage == this.Owner.Pages[0])
                {
                    this.Owner.SelectedPage = this.Owner.Pages[1]; // NO NULL CHECKING
                    this.Owner.SelectedPage = this.Owner.Pages[0]; // DIRTY HACK: users can have their own processing OnSelectedPage, which is unexpected here!
                }
                else
                {
                    RadPageViewPage page = this.Owner.SelectedPage;
                    this.Owner.SelectedPage = this.Owner.Pages[0];
                    this.Owner.SelectedPage = page;
                }

CASE 2:
 public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        public RadForm1()
        {
            InitializeComponent();
            radWizard1.Pages.Add(new WizardPage()); // when user has 100% Dpi, this code works normally. But if user has custom scale DPI (e.g. 101%), user received System.NullReferenceException: 'Object reference not set to an instance of an object.' (because because again there is no verification for ContentArea = null)...
        }
    }

Please improve the work with custom DPI scaling!

I have a winforms controls product with specific license of 2017.1.221.40 and I need to know what themes are available for this specific version and how to implement it, since I need to know if I can apply the them "VisualStudio2012DarkTheme" and how do it.

I'd like to represent, update and delete WinForms Scheduler events in a Kendo MVC Web application and visa versa. Some kind of data converter would be appreciated.

I have literally for weeks now, tried to find a single theme that works properly with High Dpi scaling, including the new material themes.  None of them work, I mean not even to the point that, it's just a few quirks.  I can't deploy applications, without extensive code to modify the way the controls look. 

My request, is take something like material (preferably with a professional color scheme), or telerik touch, make the need adjustments to make them HiDpi, and then EXTENSIVELY test it, to insure it works. 

Implement a facility to convert a RadDocument to a RadPrintDocument (or something that can be handed to a RadPrintPreview) to avoid having to load up a RadRichTextEditor just to print a code-generated document.

Do you have a version which can support Microsoft .NET Framework 2.0? I run a sample application TelerikUIforWinFormsDemoAppsHub\BugTracker asking for Microsoft .NET Framework 4.0.

We had some PC still running Microsoft .NET Framework 2.0.

ADD. New control which allows the users to play videos with different formats

Bitdefender moved a threat to quarantine. File name: c:\program files (x86)\progress\telerik ui for winforms r3 2017\examples\medicalapp\medicalappcs\bin\medicalappcs.exe. It is recommended that you run a System Scan to make sure your system is clean.

Add image editor.

For the time being one can use the WPF component with ElementHost: http://www.telerik.com/help/wpf/radimageeditor-overview.html

how to add like dislike button column for each row in radgrid

Add the ability to have multiple columns in a TreeView

Our customers are located in Russian and CIS. So, the most common language is Russian. Telerik WinForms controls doesn't provide official Russian localization. Yeah, we can translate it, but it's too hard to contact with translators and support them in translation questions. And, of course, it takes money resources. We'd rather pay more monay for Telerik WinForms UI with official Russian localization than we spend money to translators.

Thanks!

If you are using span tag in cooperation with style attribute, the following html concat "Training Room B" string:

<html><p><i><span style="font-family: Microsoft Sans Serif;font-size: 13.3px;color: #C57300;">Welcome to RoBase</span></i><i><span style="font-family: Microsoft Sans Serif;font-size: 10.7px;color: #C57300;">,</span></i><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;"> Please be aware that </span><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #C50000;">Training Room A</span><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;"> will be off limits for the rest of the week for a much needed paint job. </span><b><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #008116;">Training Room B</span></b><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;"> is still available and the Conference Room can be used if needed.</span><span style="font-family: Calibri;font-size: 16px;color: #000000;"><br /></span></p><p><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;">See Linda to reserve it. Thanks.</span></p></html>

This causes multiple controls updates which reduces the application performance. Having 3 labels will fire the event 45 times which will update the rest of the bound controls 45 times.

add more functions in rad diagram like labels for links, conditional formatting of links and nodes like shape size, color, thickness etc also try to add some analysis alogs like sna like degree, betweenness, closeness shortest path  etc. also a facility to use png icons 2d and 3d for more better representations. 

Also try to add more chart layout like tree, organic, organizational, circular, and time line to represent sequence of events related to nodes.

Why the telerik more and more ugly now? Look at the DevExpress, very beautiful and it has so many skin for change.

I hope telerik must be paid great attention  for UI. win8 it's a good example. ugly! now you also too. especially the Demo. just like a ugly collections!

Setup:
Had radchartview with showtrackball = false, and a form checkbox to enable disable the trackball

So startup showtrackball = false, the start appl, all ok, mouse over chart, all ok,   then use checkbox to set showtrackball=true, then mouse over chart all ok, then use checkbox to set showtrackball = false (again) then mouse over - and get this crash!
