Syncfusion offers a complete range of components for ASP.NET, Windows Forms, WPF and Silverlight development projects, which is not available in any other competitor including the Microsoft. It includes chart control, GridGroupingControl with options like (customizable filter option, multilevel grouping of columns, column header checkbox) DockingManager with multiple themes, Treeview item with customizable image and lazy loading of nodes. Surly I have to mention about their valuable online support, which is incomparable where team is always reachable for any kind of problem in any of the their products. They will arrange live meeting to understand exact problem and provide solutions on the spot in control modification or separate patch which will save lot of our productivity time. I will truly recommend Syncfusion for powerful products and valuable on time support. Thank you Syncfusion!
