Render a range of rows

I’m using smart rendering and I would like to render rows 100-200, is that possible? From what I’ve seen, the rendering will only let you set a buffer size but that buffer size starts from row 1 and the api does not allow for setting a position or range or rows to render.


The logic of smart rendering built in such way, that it will always start rendering from the 0 position.
While it possible to set view to necessary position , grid still will make request for data at 0 position.

    grid = new …
    grid.loadXML(data,function(){ // loading data for rows 100-200
       grid.showRow(grid.getRowID(100)); // this  command will scroll view to necessary position
