WebGrid from Intersoft Solutions Corporation has always been my favorite datagrid since I found it 5 years ago. I have built over 500 pages that used WebGrid since then, and I must say this tool is really awesome. It makes my life a lot easier with many advanced features it offerred, such as pivot charting, hierarchical custom object support and impressive editing experiences and more. Performance is also great, especially with the new client binding it offerred in its latest version. To sum up, this WebGrid from Intersoft Solutions Corporation is so far the best one I can find in the market. A must-have Grid for every serious developer!
