asynchronous loading

Hey,
I have the professional version of treegrid, and I was wondering if there was a way so that I could load the grid using multiple ajax calls. I want either something similar to distributed parsing where each call goes back to the server, or similar to smart rendering where I can specify what size chunks of data to send back (not just the total number of rows).

Is anything like this possible? If not, is there a way to override your ajax calls so I can do the above?

Thanks

The TreeGrid component supports only one way of dynamical loading - executing separate ajax calls for each branch, please check

There is no way to use smartRendering in case of TreeGrid

The grid.loadXML() can be used for dynamically adding data , this command by default add xml to existing TreeGrid structure without breaking existing one. So you can, for example, just call loadXML for different parts of TreeGrid hierarchy with time delay.
