DiagramLink.ControlPoints Property

Gets or sets a collection of the control points of this link.

Namespace: MindFusion.Diagramming
Assembly: MindFusion.Diagramming

 Syntax

C#

public List<Point> ControlPoints { get; set; }

Visual Basic

Public Property ControlPoints As List(Of Point)

 Property Value

A collection of control points that specify the link's shape.

 Remarks

You can specify new positions of a link's points through that property. The number of points in the collection depends on the Shape and SegmentCount of the link. Links made of Bézier-splines has four control points for each segment. Links of the other shapes have two control points per segment. Adjacent segments share a common control point. Check the Count property of the collection to get the number of points. After setting new positions of control points you must call the UpdateFromPoints method.

 Example

The following example demonstrates how to programmatically setup the control points of a link:

C#

DiagramLink link;
Point cpt;link = Diagram.Links[0];// Move the second and the third points
cpt = link.ControlPoints[1];
link.ControlPoints[1] = new Point(cpt.X + 5, cpt.Y);
link.ControlPoints[2] = new Point(22, 33);// Update state and redraw
link.UpdateFromPoints();

Visual Basic

Dim link As DiagramLink
Dim cpt As Pointlink = diagram.Links(0)' Move the second and the third points
cpt = link.ControlPoints(1)
link.ControlPoints(1) = New Point(cpt.X + 5, cpt.Y)
link.ControlPoints(2) = New Point(22, 33)' Update state and redraw
link.UpdateFromPoints()
