Is it possible to lock individual nodes/connectors (instead of the entire layer)?

[Mithun]

Hello Syncfusion Team,

Per the documentation, I know it is possible to lock an entire layer of a diagramComponent.

However I just wanted to check whether individual nodes/connectors could be locked without utilizing layers. 

If not, I plan to create a new layer simply to hold "locked" objects. 

Just wondering if there is a simpler way? 

PS: Something like a diagramComponent.nodes[0].lock() method would have been ideal.

Thanks,

Mithun

Hi Mithun, 

Please set NodeConstraints None to lock an individual node and NodeConstraints Default to unlock an individual  node. Similarly, you can set ConnectorConstraints None and Default to lock and unlock a connector Please refer to a code example, sample and help documentation below. 

Code example: 

  lockObject() { 

     let node: NodeModel = this.diagram.getObject("firstNode"); 

     //disable node interaction 

     node.constraints = NodeConstraints.None; 

   } 

   unlockObject() { 

      let node: NodeModel = this.diagram.getObject("firstNode"); 

      //enable node interaction 

     node.constraints = NodeConstraints.Default; 

   }

ConnectorConstraints documentation: https://ej2.syncfusion.com/angular/documentation/api/diagram/connector/#constraints
