If you delete a RadDiagramShape property using the SettingsPane (e.g. StrokeThickness) and then you try to call RadDiagram.Save() method, the generated string is not in the correct format. The deleted property is set to Auto in the string, while it should be set to 0.
Hence, if you try to load the same string, the RadDiagram throws FormatException.

SettingsPane's StrokeDashArray Combo in the Style tab is not updated correctly after save and load of diagram. 

Use a diagram, use the settings pane to set non-default value of the shape's strokedasharray.

Save the diagram. Open new solution. Load the saved diagram.

Open the settings pane on the shape you have edited before. Notice the ComboBox is not updated with the actual strokedasharray of the selected shape.

The shape positions are not correct in Firefox after HTML export if there are connection caps.

Connectors' activation doesn't work correctly with collapsed items that are on the same position as the visible ones.

Implemented functionality that detects a connection creation being cancelled through the Esc key and notifies the user

In order to take advantage of this functionality you should inherit the ConnectionTool of RadDiagram and override the KeyDown method - if it returns true the tool action has been canceled.
More about how to customize RadDiagram tools you can find in our help topic " Tools Customization": http://www.telerik.com/help/wpf/raddiagram-tools-customization.html

Ability to export a diagram to PDF.

Expose a property to set the DiagramBehaviors.TextWrapping attached property on a diagram level

Should be able to override the AbsolutePosition and the Offset of the connector. Should be able to specify absolute position manually, not only relative.

Should be able to provide template for its visual representation.

An Exception is thrown when a connection is added into a container shape in an MVVM scenario. More specifically, when you create a new LinkViewModelBase<T> and use the AddItem method of the ContainerNodeViewModelBase<T> to add it inside the container.

 Adding RadDiagramConnection in RadDiagramContainerShape doesn't work correctly in some cases:

-The container shape bounds increase each time it is expanded, when the routing of the diagram is enabled (RouteConnections=True) and you have a connected RadDiagramShapes placed in a collapsible RadDiagramContainerShape, 

-When you try to connect shapes placed in a RadDiagramContainerShape the RadDiagramConnection is not added in the container items.

-When you delete a RadDiagramConnection that is placed inside a RadDiagramContainerShape with the Delete key and then undo (Ctrl+Z) the deletion, the shape is added in the diagram items instead of the container items collection.

On graphSouce change the graphSource's collectionChanged event is not detached and because of this the diagram will still create shapes if you add items to it.

Can't paste a connection in a diagram different than the original one - the one in which the copy operation was executed.

The AllowPaste property does not work in MVVM scenario. The DeserializeNode() method in the GraphSource is called.

When user hovers a connector and pastes a connection, the pasted connection should be attached to the hovered connector.

You can check the Diagram SDK sample in GitHub - "PasteOnMousePosition" whic demonstrates this functionality.

https://github.com/telerik/xaml-sdk/tree/master/Diagram/PasteOnMousePosition

We are marking this feature request as declined - the code in the SDK sample is the preferred way to go instead of built-in feature.

XAML connections' Source and Target bindings don't work inside tab control if the diagram is not in the first TabItem.

There's a new attached property in the DiagramBehaviors - NameScopeProvider in WPF. It can be set to the RadDiagram by given element that holds the current NameScope (it's usually the root element - Window or UserControl). 

Example:
<telerik:RadDiagram x:Name="diagram"
telerik:DiagramBehaviors.NameScopeProvider="{Binding ElementName=root}"       ... />

Memory leak when you close a window that holds a RadDiagram. The RadDiagram and its shapes are not cleared.

User sometimes need to use a Static Ruler which does not scale when you zoom the Diagram. Or when you pan. Just line with star 0, ticks, end 1024 for example. This line does not move and does nto scale.

There is no easy way to achieve this. UpdateScale method is private. It could be protected.

====

In Q1 2014 SP DiagamRuler will draw itself and its ticks when its Diagram property is NOT set.

Implement functionality that notifies the user when a shape is dragged out of a container.
