Fixed height / number of rows for subgrid


Is it possible to have the subgrid with a fixed number of rows (or fixed height).
And then have a vertical scroll bar to load data dynamically with smart rendering?


Unfortunately the performance increasing techniques are not supported in subgrid.
You may try to use “sub_row_ajax” excell with the link to the page, containing the grid with smart rendering.
Also you may try to use dhtmlxtreeGrid.
