We have released version 4.3.1 of MindFusion.Diagramming for ASP.NET MVC. It adds the following new features and improvements:

Node constraints
The constraints property lets you apply size and direction constraints to a node. It returns a NodeConstraints object with following properties:

• keepRatio: a bool value indicating whether the initial width/height ratio of a node should be preserved.
• maxHeight: the maximum node height allowed.
• maxWidth: the maximum node width allowed.
• minHeight: the minimum node height allowed.
• minWidth: the minimum node width allowed.
• moveDirection: a member of the DirectionConstraint enumeration. Set it to Horizontal or Vertical to let users move a node only in specified direction.

These constraints are considered when a user modifies the node interactively. They are ignored if node placement is changed programmatically by using API methods and properties.

Tag Helpers
The following tag helpers can now be imported from MindFusion.Diagramming.Mvc namespace:

• <mindfusion-diagramview> creates a DiagramView instance.
• <mindfusion-ruler> creates a Ruler instance.
• <mindfusion-zoomcontrol> creates a ZoomControl instance.
• <mindfusion-overview> creates an Overview instance.
• <mindfusion-nodelistview> creates a NodeListView instance.

@addTagHelper *, MindFusion.Diagramming.Mvc
....
<mindfusion-diagramview
    component=(DiagramView)ViewBag.DiagramView
    style="width:100%; height:100%;">
</mindfusion-diagramview>
 

Distribution for the latest version can be downloaded here, or from the clients area on our site:
