Looking for best solution to implement AJAX TreeGrid

I'm looking for a Ajax/TreeGrid (Tree with multiple columns) implementation.

It has to:

  1. support server side sorting
  2. support on demand leaf loading - only children of open nodes are loaded
  3. support paging - nodes have to be loaded in chunks, only visible records are requested from server
  4. be free to use in commercial project

I tried Dojo (dojox.grid.LazyTreeGrid) and it seems to have problems with pagination.

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.
