Replace the original panel

I have a page like this:

On the far right is my custom panel, I want the data in the original panel to be bidirectionally bound to the data in my own panel.
Excuse me, What method can I use to get all the data of the original panel?
What method can be used to update new data to the original panel?
thanks for your help!

Why do you have two properties panels in the first place? Why not extend the existing properties panel?

In fact, I have implemented the extended property panel, but my manager feels that the original look is not beautiful…

Is there any way to get all the property values of the currently selected node?

The buisinessObject seems to be what you’re looking for.

I know this, just taking the value from the buisinessObject, I think it is too cumbersome, I want to know if there is a more elegant way.

What would be a more elegant way in your opinion? The businessObjectcontains all the information you’re looking for.
