Virtual mode for UltraTree
posted

Is it possible to implement virtual mode for multicolumn UltraTree similar to virtual mode in UltraGrid?

I need to load potentially very large set of data (100k rows or more) with up to a 100 columns in each row but I already see performance degradations when I try to load 1000 rows. Can you please advice on best strategy to handle large amounts of data in UltraTree.

Thanks

    Are you binding the tree or adding data to it manually?

    Forgot to mention I'm using UltraTree in a FreeForm mode. I saw some posts about using AddRange instead adding node by node to speed things up but how do I set cell values on a node that hasn't been added to node collection yet and doesn't know about node collection's columns? Virtual mode would still be the best approach though.
