We are using Coqsoft Treegrid component in out web application. Though it has many cool features, it is native code (developed in C++) and a bit difficult to maintain. Could somebody please suggest a better option.
I also need grouping (multilevel) by columns.
Thanks
This is a very good question, though a little subjective. I am still looking for the "best" one myself.
I would say that ExtJS is great, though it is not free for non open source projects (GPL) it has an LGPL branch (of which legitimacy is disputed). ExtJS got a lot of criticizm for changing licenses (LGPL, to GPL)
GWT-EXT library was a good alternative (based on the LGPL branch) but it was discontinued and replaced by Smart GWT (if you like GWT) based on the SmartClient UI framework
I have used ExtJS in the past, it's pretty good and easy to use. I think you can download it for free http://www.extjs.com/
I like the jQuery Grid plugin: http://www.trirand.com/blog/. Quoting this blog post:
Some features of jqGrid:
- paging functions
- add, edit, delete & search records
- accepts XML, JSON, array or user data as input
- multiple selection of rows
- sub grid & grid details (great feature!)
- UI datepicker integration
- & more...
jqGrid is very impressive with the interface, features, usability & documentation.
See the demo page here. Also Check out jQuery Grid Recommendations for other (jQuery) alternatives.
