After a project, built with the standard MS controls, is successfully converted to a Telerik WinForms project, the subscriptions to certain events available in the Designer.cs file may disappear if you open the design view and make some changes. A solution for this behavior is described in the How to Deal with Disappearing Event Handlers after Opening the Designer for a Converted WinForms Project KB Article.

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>());

I know it is not an easy task.

I love the new vb.net form conversion to telerik form .

Could you please make one from vb6 to telerik form conversion. I know I am asking for a lot but I am pretty sure your sales is going to skyrocket with this feature.

Please think about it.

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

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.

If you currently install the nuget package "UI.for.WinForms.Themes", all themes are loaded and referenced. If you only use one theme in the application, you have to remove all others manually. It would be nice if there was an extra package for each theme.

Is it possible to add a Hamburger Menu to the Telerik UI for WinForms?
like: https://docs.microsoft.com/en-us/windows/uwp/design/controls-and-patterns/navigationview

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.

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.

Currently the only way to have this work on a windows 10 machine with vs2017 is to install a depreciated version of Build tools 2015. Which causes some conflicts with vs2017 backwards compatibility.

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.

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.

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.
