Hello Infragistics-Team,
As I can see, there are currently a lot of problems with the compatibility of the infragistics UltraWebGrid component and the newest version (3.6) of Mozilla Firefox.
One problem I haven't found mentioned yet in this forum is related with the collapse button on the left, which shows up when hierarchical data is bound to the grid. Expanding the rows works fine in FF 3.6, but I'm not able to collapse the rows again. That is, the complete grid is not usable in FF 3.6 and it's very important for our business.
I hope you'll fix it in 2010/1 !
Thanks for your help,
Michael Dafino
