If you define a single WizardPage in the WizardPages collection and set its AllowFinish property to False, the Finish button is enabled.

To work this around, set the AllowFinish property in the Loaded event handler of the WizardPage control.

private void WizardPage_Loaded(object sender, RoutedEventArgs e)
	var page = (WizardPage)sender;
	page.AllowFinish = false;

Importing padding CSS style property with shorthand value produces an incorrect result. 
Importing padding: 5px; style is imported as padding-top: 5px, padding-right: 0px, padding-bottom: 0px, padding-left: 0px

Padding syntax can be seen in the specification.

Workaround: Apply padding values for all four sides.

Selecting a large number of items through the UI or programatically with the Select method when in Extended SelectionMode leads to a degraded performance. As a workaround the Multiple SelectionMode can be used instead.

To reproduce; 

- Set the language to Korean

- Type "r" in one of the cells

- Use the AutoFill functionality

At this point, FatalExecutionEngineError occurs (see attached).

Unsupported annotations are rendered on top of other content. When there is a form field that appears inside the annotation, it cannot be clicked or interacted with as the annotation is capturing the mouse gestures.

WPF controls are used to visualize the form fields in PdfViewer. However, these controls inherit the background defined in the PdfViewer's theme instead of a background of the form field control. This leads to wrong visualization mostly in the dark themes as the content inside the form field might get unreadable.

The WPF .NET Core 3 packages reference assemblies from SharpDX project. For one, these assemblies only work with .NET Framework 4.x. In addition, the project will not be developed further and there will not be a version compatible with .NET Core 3.x or later versions. I consider this as a serious bug and Telerik should think about removing the SharpDX assemblies and swapping it for another. Even if my project compiles without errors, you always have the warning signs on the dependencies.

To reproduce: 

- Select some cells within the same column using Ctrl+Click

- Use the context menu to copy the cells

This works in Excel when the cells are within the same column.

- Click the "Go To endPosition" button. The Caret remains on the same line.

If you change the DataContext property of WizardPage at run-time, the context in the content presenter that shows the footer is not updated accordingly. 

To work this around you can create a custom WizardPage and manually set the data context of the footer presenter.

public class CustomWizardPage : WizardPage
	private ContentControl footerContentControl;

	public override void OnApplyTemplate()
		this.footerContentControl = this.GetTemplateChild("PART_FooterContentControl") as ContentControl;            
		this.DataContextChanged += CustomWizardPage_DataContextChanged;            

	private void CustomWizardPage_DataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
		this.footerContentControl.Content = e.NewValue;

	<local:CustomWizardPage />

The style name "+-" is a valid one, but the StyleGallery crashes because it tries to set the name as a value of a cell and it is not a valid cell value.

1. Open RadRichTextBox
2. Click to Home tab -> Paragraph group-> Multilevel list button
4. Click to "Define New List Style"
5. In "Apply formatting to" select 4th level. Don't select '1','2','3' beforehand, select '4' right after '1'st level.

Observed result: All text except the 4th level is bold.

Expected result: Only 4th level text is bold.

When using OpenStreetMaps with APIKey (required for Cycle and Transport variations)

the key is not automatically passed to the builtin minimap and it shows 'Api Key Required' in some tiles.
