Looking for best solution to implement AJAX TreeGrid
ajax, dhtml, javascript, treeview
Solution
ExtJS's TreeGrid meets all your criteria except for the last one. Our implementation uses server-side sorting and on-demand loading/creating/deleting/moving of child nodes on the client, and then we push that data back to the server for persistance.
Ext is a huge framework, but you can take advantage of their dynamic loading to keep your page load times short.
You can download it for free to see if it's a good fit and perhaps decide if it's worth licensing.
Problem
I'm looking for a Ajax/TreeGrid (Tree with multiple columns) implementation. It has to: - support server side sorting - support on demand leaf loading - only children of open nodes are loaded - support paging - nodes have to be loaded in chunks, only visible records are requested from server - be free to use in commercial project I tried Dojo (dojox.grid.LazyTreeGrid) and it seems to have problems with pagination.
