I am primarily lloking at their Grid (For data entry) but see that there seem to be a lot of nice other formatting controls also

They seem to have ano. of different options and am not sure whcih one to select. (Windows Forms, Web Forms, Asp, WPF....all a little confusing) They also now seem to have a lot of stuff on WPF. To use the WPF stuff and Stratframe, I presume I will need to wait until the next version of SF ?

In the past I purchased a few Web Controls (Telerik Grid) and found that it was quite slow.

Thanks in advance
