At the moment one needs to iterate all controls and set the EnableCodedUITests property individually. It would be nice if there is a way this to be done only once affecting all controls.

To reproduce:
The result of the following line is always null:
var test = ThemeResolutionService.GetTheme(ThemeResolutionService.ApplicationThemeName).FindStyleGroup("Telerik.WinControls.UI.RadLabel");

Workaround:
var test1 = ThemeResolutionService.GetTheme(ThemeResolutionService.ApplicationThemeName).FindStyleGroup(new RadLabel());

When a child form is opened in a new thread, and tooltips are used in the child form, cross thread exception is thrown, due to the fact that RadToolTip internally uses a static control instance.

 public class ManagedThread
    {
        private Thread _thread;
        public ManagedThread()
        {
            _thread = new Thread(new ThreadStart(OpenNew));
        }

        private void OpenNew()
        {
            Child form = new Child();
            form.Text = "my text";
            form.ShowDialog();
        }
}

The second time the child form is opened, when you try to show tooltips of a control e.g. RadDropDownList with ToolTipTextNeeded, the exception is thrown.

Workaround: use screentips instead of tooltips: http://docs.telerik.com/devtools/winforms/treeview/how-to/assign-radscreentip-to-nodes

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>());

After revamping the documentation for the Telerik UI for WinForms product, the following problems occurred:

1. Search for a specific class or method in the search box in the following site: https://docs.telerik.com/devtools/winforms/introduction. Select one of the results referring to the API documentation. As a result you will be navigated to the main page of the API reference instead of to the respective class or method. Refer to the Problem1.gif file. It seems that the search results from the API reference return old links for the previous API link pattern.

2. The search box in https://docs.telerik.com/devtools/winforms/api/ is significantly lagging while typing. We should consider performing the search operation after pressing Enter and not with each keystroke. Please refer to the Problem2.gif file.

3.  When you scroll the navigation view on the left side to a certain position and select an article, the vertical scrollbar sometimes gets reset to the top position and you have to scroll back.  (Note that this problem is not reproduced each time).

Host a Panel in RadHostItem and set the BackColor of the Panel. You will notice that the color set is not applied.
NOTE:   These properties should be set to the RadHostItem
