All of my comments are specifically about Developer Express's XtraGrid for Windows forms. I have built several Windows forms application using Dev. Express, and I like Developer Express's grid for the following reasons. 1. The grid is incredibly fast, I have yet to test a faster grid, when it comes to getting large numbers of rows into the grid. 2. The grid is very stable, if you are a good programmer, you will never see any exceptions thrown. 3. The grid supports all of VS2005's new binding features like BIndingSource. 4. The grid's group-by features are the fastest I have ever tested. 5. The grid's event model is excellent. 6. Dev Express uses enums for grid anatomy instead of having to do String compares in other grid components that I have looked at. If you are using custom business objects (not datasets), then you will really love the Sorting Cababilities, they are built-into the grid: Your custom business objects will automatically get sorting (including multi-column sort), without writing a single line of sorting code. General Support: Their support is adequate. Documentation is good. Source Code: You can buy it. This is very important, as who would build in a dependency of this magnitude (meaning the grid) without source code. What if the vendor were to go out of business? And finally, Developer Express's grid control is very well engineered. I have examined the source code and Dev. Express's is most impressive! You can not go wrong purchasing this Grid Control.
