Hi all,
how could we be able to expand/collapse a treeview without passing by the needdatasource event ?
I mean:
we have a page with a treelist control.
The first load (!page.ispostback) we need to load it empty. The second load (page.ispostback) we load the treelist control with the results of a filter options.
If we click on expand/collapse button it doesn't work (expand/collapse)
Every time we start an event, treelist goes on needdatasource event to load the object.
How could we be able to expand/collapse a treeview without passing by the needdatasource event , load it and click on expan/collapse button to expand or collapse nodes?
Hope you undestand.
Thank you
BR
