I'm using the XCeedSoft component suite, including the grid, for nearly 2 years, and I'm highly satisfied. Especially the grid and the chart components are hard to beat. Besides this, XceeSoft is developing in quick cycles, and if your are a subscriber of their 'vanguad priority support' - which is recommendabel because of the complexity of the components - you get all updates automatically and free. Support ist excellent; normally your get an answer within 24 hours. Web based support for developers is also good (the knowledge base could be somewhat more complete, but the product documentation is good). Not to forget that the Xceed grid was chosen by Microsoft as the standard add-on in the new MS-Office to come. And many of the big 'blue chip'-companies in the world are using the XceedSoft components. Maybe this alone should suffice to make your own choice .... (Wolfgang Sohst / Berlin, Germany)
