I'm comparing the latest versions of Xceed, DevExpress and Infragistics datagrids here. Xceed is by far the nicest to work with, and also the most feature-rich, but unforunately, it is also by far the worst performing.   In my example, I have 100,000 rows and 3 columns based on an in-memory collection of custom objects. For all grids, I've ...

In the past two years, Xceed has worked on the performance of Xceed DataGrid for WPF, and with August's release of v3.0, we feel we've achieved a great level of performance. The best in the industry if you not only count scrolling speed, but loading, sorting and grouping time as well. Despite the new performance increases, ...

Thanks, but how do you know this is the fault of the graphics programmer?  First of all, it could be a graphics card driver issue, I'll talk about that later.

So ...unscientific is all we can provide at the moment. On my Dell Vostro 400, which is a <$1000 business desktop, I just ran the latest nightly build to ...

I saw a post saying you plan ''virtualization'' performance improvements from v2.1.  Can we get some metrics?   Can we get numbers about how well grids scroll large sets (specific grid sizes, 10x100, 15x1000, 25x2000, etc) ?   I.e. frames or rows per second?   I find that the current V2.0 DataGrid is UNUSABLE at ...
