We have a requirement where we drag custom nodes on canvas say for example 4 custom node.
When we try to connect the two nodes we need to change the node border color of all the nodes which are available on canvas as per business logic.
But we didn't found any event other than mentioned below.
All the above event gets fired when two nodes are connected.
Is there any event which will get raised as soon as we start to connect the two nodes.
For eg when we will try to connect head node with tail node as soon as connector line is being dragged then the border color of all the node has to be changed.
