I'm using the Infragistics ultrawebgrid for the hierarchical grids in my ASP.NET 2.0 app, and 99% of my users have no problem viewing the grids. However, 3 users only see the header and footer of the grids even though there's data to be displayed. There's a javsascript error on the pages: "The value of the 'method' attribute may not be 'html'." I can't seem to find the common factor with these users. Can anyone shed some light on this? Thanks.
