Requirements:

- Multiple screen RDP-Session with option "Show windowcontents while dragging" turned off.

- RadTabbedwindow with AllowTransparency = false (might not be necessary)

When dragging a maximized TabbedWindow to a different screen into maximized mode, it is allways maximized on the primary screen.
Dragging it on the target screen so that it is not maximized and then clicking maximize works.

The issue only appears when the mentiond setting in the RDP-Session is turned off.

When trying to import a document containing bookmark and BookmarkRangeEnd is after the last paragraph, a StackOverflowException is thrown in IntervalNode while trying to rebuild the document cache. (RadDocumentChildrenCache.RebuildTree()).

The same could be observed if the bookmark end is last in the header/footer, between table cells in the RadDocument body, or when all paragraphs after the bookmark range end are hidden (with vanish property).

Workaround: Detect the problematic annotations and remove them:
foreach (var rangeStart in document.EnumerateChildrenOfType<AnnotationRangeStart>())
{
    if (rangeStart.End == null || rangeStart.End.Parent == null || rangeStart.End.Parent.Parent == null)
    {
        //MessageBox.Show("This indicates a problem.");
        rangeStart.Parent.Children.Remove(rangeStart);
    }
}

Note: Until 2017 R2 SP1 release StackOverflowException is thrown, after this release an ArgumentException should be thrown.

Expose an event that allows you to cancel the navigation to a folder. For example, if you enter an address in the breadcrumb, click the back button, or select a directory in the navigation tree, then you should be able to cancel the navigation.

This can be done via a new event that have a Cancel property in its arguments, for example.

The naming shown here is not mandatory.

When the ItemsSource is not set: ArgumentOutOfRangeException is thrown

When the ItemsSource is set to an empty collection: DivideByZeroException is thrown

RadRibbonDropDownButton DropDownIndicator isn't rotated when the DropDownButtonPosition is Right and the DropDownPlacement is Right

The native radio button supports validation. Implement validation for the RadRadioButton

Currently it's not possible to disable the fill handle feature. Provide API for disabling it.

Workaround: in the attached project.

Steps to reproduce:

1. Place a camera on a window

2. Have no camera plugged in the PC

3. Call the Start or Stop method

Expected behaviour: Nothing 

Actual behaviour: An exception is thrown

If you have an XML attribute with a string value, but the value is not fully rendered into the viewport, its color defaults to black, instead of the expected blue color.

To work this around, you can create a custom XmlTagger and override its GetTags() method. This will allow you to properly catch the string value and return it as a tag span element with its ClassificationType set to "string".

Drag and drop from Visual Studio Toolbox to the designer area doesn't allow you to drop the corresponding control inside the content of the selected tab item. 

To work this around, add a Grid panel with transparent background inside the RadTabItem's in XAML. You can do this also  through the toolbox.

 <telerik:RadTabItem x:Name="RadTabItem1" Header="Tab item 1">
	<Grid Background="Transparent" />
 </telerik:RadTabItem>
