Huge Performance Boost

The main addition to version 3.0 is the immensely improved performance. The diagram rendering engine can now support thousands upon thousands of diagram elements. This is mostly noticable by the dramatically improved loading time. All other operations such as panning, editing and exporting have also been improved for large diagrams.

Connection Bridges

Another nice improvement to the framework is the ability to render bridges over intersecting connections. Managing the potentially large number of intersecting points has been made possible thanks to performance improvements mentioned above.

The connection intersections are always calculated, but by default the bridges are not rendered – all you need to do is switch them on. This is done by using a CorneredPathBuilder which is responsible for taking the logical connection model and generating the path geometry. To use this, you create a new connection style in the usual way and set the PathBuilder to be a CorneredPathBuilder with the IsIntersectionBridgingEnabled property set to true. Below is a simple example of how to do this:

<ms:CorneredPathBuilder x:Key="PathBuilder" IsIntersectionBridgingEnabled="True" CornerRadius="0" />
 
<Style x:Key="ConnectionPathStyle" TargetType="Path">
  <Setter Property="Stroke" Value="Black" />
  <Setter Property="StrokeThickness" Value="2" />
</Style>
 
<Style x:Key="ConnectionStyle" TargetType="ms:DiagramConnectionElement">
  <Setter Property="PathBuilder" Value="{StaticResource PathBuilder}" />
  <Setter Property="PathStyle" Value="{StaticResource ConnectionPathStyle}" />
</Style>
 
<ms:FixedStyleSelector x:Key="ConnectionStyleSelector" Style="{StaticResource ConnectionStyle}" />
 
<ms:DiagramFormatter x:Key="Formatter"
                     ConnectionStyleSelector="{StaticResource ConnectionStyleSelector}" />

Last of all you would set the Formatter of the DiagramSurface to be the DiagramFormatter in the code above.

Other Changes

Like most major releases, there are a few breaking changes in Diagrams 3.0. These changes are all very minor and you can see how to work around them in the Release Notes section of the help docs. One change that will most likely impact you is that we removed DiagramSurface.ShowConnectionPoints property. To work around this, you simply don’t need to set this property to True anymore so it can be removed.

Also, as always, there’s a bunch of bug fixes and general improvements.
