Hi RakhiS,
Greetings from Syncfusion Support.
We checked with your reported query and in order to assign unique id’s to the panels, you have to specify the id attribute. However, unique id will be generated for panels when id is not specified. In the below sample, you can see that the default id gets generated when not specifying it. And we have specified a custom id while adding the panels.
Refer to the sample.
Please get back to us if you need further assistance.
Regards,
Sharon Sanchez S.
