How to Prevent Node When Clicking a Button in HTML in React Diagram?

In Syncfusion® React Diagram, nodes can contain HTML templates with interactive elements, such as buttons. When clicking these buttons, you may want to prevent the node from being selected. This can be done by handling the selectionChange event, which is triggered whenever a selection attempt is made.

This guide demonstrates how to prevent node selection when clicking a button within the node’s HTML template by checking if the active element is the button and canceling the selection process by setting args.cancel to true.

// Function to handle the selectionChange event
selectionChange={(args) => {
 // Check if the currently focused element is the button inside the node
 if (document.activeElement && document.activeElement.id === 'buttonInsideNode') {
   // Cancel the node selection
   args.cancel = true;
 }
}}
