Hi Tim
Thanks for the update.
We suggest you to use “SelectionChange” client side event in order to achieve your requirement. Please refer the below code snippet and sample for your references.
Code snippet:
//define selectionchange event
DiagramWebControl1.OnClientSelectionChange = "selectionchange";
function selectionchange(args) {
var diagram = $("#DiagramWebControl1").ejDiagram("instance");
if (args.element) {
var node = diagram.selectionList[0];
if (node) {
if (args.changeType == "insert") {
diagram.updateNode(node.name, { borderColor: "red", width: 150 });
}
if (args.changeType == "remove") {
diagram.updateNode(node.name, { borderColor: "black", width: 100 });
}
}
}
}

Please let me know if any concerns.
