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!

How to reproduce: store an image on the file and try to use it this way string path = @"D:\img.png"; this.radLabel1.Text = "<html><img src=" + path + "><b>Test</b></html>"; Workaround: if possible embed the image in the assembly and use it as a resource this.radLabel1.Text = "<html><img src=res:_1133506_RadLabelLinkHtmlLike.img.png><b>Test</b></html>";

The RadRibbon when running under VisualStudio2012 dark theme is not able to properly display the buttons such as edit etc. The dark background with dark image causes this. Your WPF example outlook application lists a theme that is very similar but with a lighter color on the buttons. Would it be possible to get access to this theme? Thanks, Ronny

To reproduce add RadGroupBoxElement in another control (for example in a ribbon group) and use the VisualStudio2012 theme.
Workaround: either open the theme and set the GroupBoxElement theming to be reused in other controls or use the following snippet to do the same:
private void FixTheme()
{
string controlType = "Telerik.WinControls.UI.RadGroupBox";
StyleGroup styleGroup = ThemeResolutionService.GetTheme("VisualStudio2012Light").FindStyleGroup(controlType);
styleGroup.Registrations.Add(new StyleRegistration("ElementTypeDefault", "Telerik.WinControls.UI.RadGroupBoxElement", controlType, string.Empty, string.Empty));
}

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.

Release R1 2021 SP2

Feature Request
When a RadSvgImage document is modified the cache of raster images needs to be cleared, so the modifications can be visualized.
For example we want to change the following SVG
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 16 16">
<defs>
<style>.cls-1{fill:none;stroke:#228bcb;stroke-miterlimit:5;stroke-width:1.2px;} </style>
</defs>
<g id="undoModern16">
<g id="icon">
<path class="cls-1" d="M5.61,10.36.82,5.51,5.61.63M9.5,14.5h1.28A4.51,4.51,0,0,0,15.38,10h0a4.52,4.52,0,0,0-4.6-4.5H.82" />
</g>
</g>
</svg>
Here is how it looks 
To change the color of this SVG we need to change the stroke color of the path that represents the arrow. First, we need to find the element of type SvgPath and then set its stroke to the desired color.
RadSvgImage svg = this.buttonUndo.SvgImage;
Svg.SvgPath path = svg.Document.Children.FindSvgElementOf<Svg.SvgPath>();
// set arrow color to gray(51,51,51)
path.Stroke = new Svg.SvgColourServer(System.Drawing.Color.FromArgb(51, 51, 51));
// no API to reset the cache
As a workaround we need to reassign the image of button:
// clear the cache of RadSvgImage
this.buttonUndo.SvgImage = null;
this.buttonUndo.SvgImage = svg;Another possible workaround when working with LightVisualElement and its derivatives is to clear the cache with reflection:
var fi = svg.GetType().GetField("cachedSizesToImages", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
fi.SetValue(svg, new Dictionary<Size, Bitmap>());
