Page by page data load in TreeGrid

I have a TreeGrid. I am using 3.0 Pro version.

I want to load data from database one page at a time.

Is there an API on front end side which helps me do it?
Is there any sample backend code. I am using Python/django in backend but sample code in any language will do.

Please point me to right documentation.


Unfortunately the dynamic loading in treegrid works by levels only. … namic.html
nodes of the parent level load at the first. Expanding of the node occurs the loading of the node’s content.
