Hello!
I just bought pro version and have first problem:
I need to use both: SmartRendering to dinamic loading grid () and Tree feature to make some grups () but I can’t get it work.
Please, post some example.
SmartRendering mode availalble for plain grids only ( in case of tree-grid the order of row changed by each open-close operation so prediction is not usable )
For TreeGrid you can try to use dynamical loading
samples/pro_treeGrid_dynamic.html
In such mode tree loads content of sub-branches by additional AJAX request - this allows to show unlimited hierarchy.
