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. 

Use attached project to reproduce. 

Workaround:
Use attached theme.

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.

This request is for control similar to RadImageEditor in ASP.NET AJAX suite: http://demos.telerik.com/aspnet-ajax/imageeditor/examples/overview/defaultcs.aspx

Workaround: use a bigger image 
Me.radCheckBox1.ButtonElement.CheckMarkPrimitive.CheckElement.ShouldPaint = False
    Dim dpi As Point = NativeMethods.GetSystemDpi()
    Dim scale As Integer = dpi.X
    If scale >= 300 Then
        Me.radCheckBox1.ButtonElement.CheckMarkPrimitive.Image = Image.FromFile("..\..\check-mark.png")
    ElseIf scale >= 200 Then
        '...
    Else
        '...
    End If

Similar to Material Themes Blending (https://docs.telerik.com/devtools/winforms/tools/visual-style-builder/working-with-visual-style-builder/material-themes-blending) provide an easy way to change the palette for the Fluent themes. 

Hello,
i have a suggestion for WinControls, please add a comfortable language Support
without methode override. Please create a property field Pull-Down Menü in every Control
where Developer can change the language of the control in e.g. englisch, spain, german and so on. The translation could be done very quickly with the help of the Telerik community and their experience.

How to reproduce: check the attached project and compare the font size of the two labels. Also when the form is moved from a screen with HDPI to a standard screen with DPI=96 the font does change.

To reproduce:
- Open Theme Viewer, go ListView and sort it.
- Change the theme to Fluent. 

 Workaround:
- Set the visibility of the item in the theme (see attached). 
 
 

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.

Should be able to generate industry-standard barcode formats.

We load a default theme and modify it in code. This works great and allows for great flexibility.

The problem is that this adds a pretty substantial overhead to the application start.
It would be great to have a way to save the modified theme as a file so if there are no changes to be made since the last start, we could just load this files instead of executing all the customizing code.

Benefits from this approach:
* Multiple developers can change the code at the same time without any conflicts.
* The theme can be updated with every new Telerik version without any work on our side.
* We can use different base themes and apply the same customizing without the hassle of maintaining multiple files and the danger of getting out of sync.

Workaround: 
The vsdiffmerge.exe merge tool in Visual Studio 2017 is usually located here: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer. You will need to create one additional folder named Ide inside the Team Explorer folder Then you can copy the vsdiffmerge.exe file from the Team Explorer folder to the newly created Ide folder. You can check the attached vsdiffmerge-path.png screenshot.

Then you can create the environment variable like this:
Variable name: VS120COMNTOOLS
Path: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\IDE

The ImageList property is visible in the Properties section of VisualStudio for RadTextBox, RadTextBoxControl etc.

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

How to reproduce: set the MinimumSize property of a RadButton in a DPI-aware app
