DiagramNode.EnabledHandles Property

Gets or sets the kinds of modifications that end-users are permitted to perform on the node.

Namespace: MindFusion.Diagramming
Assembly: MindFusion.Diagramming

 Syntax

C#

public AdjustmentHandles EnabledHandles { get; set; }

Visual Basic

Public Property EnabledHandles As AdjustmentHandles

 Property Value

A combination of the AdjustmentHandles enumeration members. The default is AdjustmentHandles.All.

 Remarks

Disabling some selection handles allows restricting the types of modifications that users can perform on a node. Each manipulation handle can be enabled or disabled by setting or clearing the respective flag in the combination.

For example, to make a node resizable only horizontally, set this property to a combination of the Move, ResizeMiddleLeft and ResizeMiddleRight flags. That will disable all manipulation handles, except the left and right ones, which allow horizontal resizing, and the central one allowing movement of the node.

 Example

The following code disables the rotation handle of a shape node:

C#

node.EnabledHandles = AdjustmentHandles.All & ~ AdjustmentHandles.Rotate;

Visual Basic

node.EnabledHandles = AdjustmentHandles.All And Not AdjustmentHandles.Rotate
