How to Determine Node Selection Programmatically in React Diagram?

This article explains how to determine node selection programmatically in React Diagram. In our Syncfusion® React Diagram, nodes can be selected either through user interaction or programmatically. To select nodes via user interaction, the user can simply click on the nodes. For programmatic selection, you can use the select method.

let node = [
 {
   // Position of the node
   offsetX: 250,
   offsetY: 250,
   // Size of the node
   width: 100,
   height: 100,
 },
]; 

<DiagramComponent
       id="container"
       ref={(diagram) => (diagramInstance = diagram)}
       width={'100%'}
       height={'600px'}
       nodes={node}
     /> 
     
function rendereComplete() {
   diagramInstance.fitToPage();
   diagramInstance.select([diagramInstance.nodes[0]]);
}
