The ability of treegrid is that it displays tabular information organized into nodes, so you can quickly navigate through your data without having to manually sort or filter rows. It's simple enough for new users but allows advanced features such as drag-and-drop reordering and filtering options if needed. I dislike how difficult it is to create custom filters and sorting rules; however, they do offer an API service (TreeGrid Web Service) which offers easier access. We use this tool extensively with our customers and have been very happy with its performance and ease of use. Customers love being able to easily share their project plans with us and keep track of progress throughout each stage of the construction process. This has helped ensure we are meeting our deadlines while keeping costs down!
