If series datasource is ordered, asc or desc, all actions that serch a subset of data can be ultra speed. At the moment working with large datasets and zoom/trackbals cause occasional chart freeze.

Possible solution:

1) Declarative: The developer declare that the dataset is ordered asc/desc.
2) Automatic: On points add/remove chart verifies if data is ordered.
3) Programming: Chart allow to override serch in database functions.

My suggestion is 1) or/and 3)

When the RadRibbonSplitButton fires the command everything works fine.

When the RadMenuItem inside the RadRibbonSplitButton.DropDownContent fires the same command, the "this.Cursor = Cursors.Wait;" inside the method has no effect.
The Cursor doesn't change.

See the attached sample application

Decline Reason: This behavior is expected and it comes from the WPF native Popup element which hosts the button's DropDownContent. Basically, when the split button is clicked and the Window Cursor is changed, the mouse is over the window before the application freezes and you can see that it is changed. On the other hand due its specifics the Popup is not placed directly in the Window (it is rendered into a separate visual tree) and when the Window's cursor is changed, you won't see it because the mouse is not over the Window. So, the application freezes before the mouse gets over the window. You can resolve this by setting the Popup Cursor property or the static Mouse.OverrideCursor property.

My RadTreeView is bound to VirtualQueryableCollectionView. Changes on Filter and Sort Descriptors works fine but calling to VirtualQueryableCollectionView.Refresh() method throws a NullReferenceException with the following stacktrace:

The document default style properties are not cloned on document.Clone().
There is a workaround by using the following code:

var cloning = this.document.Clone();
ClearPropertiesWithoutValueAndSetLocalValues(this.document.DefaultStyle.CharacterProperties, cloning.DefaultStyle.CharacterProperties);
ClearPropertiesWithoutValueAndSetLocalValues(this.document.DefaultStyle.ParagraphProperties, cloning.DefaultStyle.ParagraphProperties);

private void ClearPropertiesWithoutValueAndSetLocalValues(DocumentElementPropertiesBase propertiesFrom, DocumentElementPropertiesBase propertiesTo)

{
	foreach (var stylePropertyFrom in propertiesFrom.StyleProperties)
	{
		var stylePropertyTo = propertiesTo.GetStyleProperty(stylePropertyFrom.PropertyDefinition);
		stylePropertyTo.ClearValue();
		if (stylePropertyFrom.HasLocalValue)
		{
			object value = stylePropertyTo.GetLocalValueAsObject();
			stylePropertyTo.SetValueAsObject(value);
		}
	}

ParagraphMarkerProperties of a Paragraph element are not cloned and this leads to incorrect list numbering (bullets) rendering after export since the numbering styles (bullets, numbers and etc.) copy the style properties from there.
This affects Clone() method of the Paragraph and ergo RadFlowDocumentEditor.InsertDocument() method and DocumentElementImporter.Import() methods since they're using Clone() method internally.

Hello,
Like a lot of companies we have multiple client side interfaces of a single application and have to create similar UI in multiple platforms.
For example I had to create a chart in both WPF and ASP.NET AJAX today.
The problem I have with the Telerik controls is that there are absolutely no standardization or consistency between platforms.
Why in the name of all-things-good-in-this-world are axes in WPF and ASP.NET AJAX and ASP MVC and Windows Universal Apps not all called the same thing?
It would be very simple to use interfaces to create some consistency between platforms.
Even better would be if Model Views are shared across platforms in a portable library:

https://msdn.microsoft.com/en-us/library/gg597391(v=vs.110).aspx
Regards,
Douw
PS. I could not find a feedback portal for all platforms, so have to log this multiple times.

The themes are great. But it's difficult to create a new one from scratch. It'd be great if there was a Theme Creator/Editor that allowed a designer to start from scratch, or create a new theme based on an existing one. The UI would allow the designer to preview the new theme in real time against live theme-supporting Telerik controls and see the results. 

i would like to change background color when click in (Day,Month,Week,Timeline).
