Hi,
I'm upgrading from UltraWebGrid to the new WebDataGrid and I've been dealing with significant performance issues in IE8. The grid has about 45 columns and 100 rows. In UltraWebGrid, this was not an issue. However, the new grid takes 2-3 times as long to load (~10 seconds), and selecting a cell literally takes ~5 seconds compared to ~.5 seconds in the old grid. The grid performs poorly in Firefox as well - only Chrome seems to provide good performance. However, I need it to work in IE8. The exact version of IE is 8.0.7601.17514.
Also, paging isn't really an option based on the business requirements, but shouldn't the new grid perform better anyway?
Thanks,
Mike

a/b) I'm using version 12.1 of NetAdvantage, and I'm using the 3.5 version of the assembly (Infragistics35.Web.v12.1.dll), with runtime version v2.0.50727
c) Yes. Virtual scrolling does improve the performance slightly, but it's still nowhere near the old UltraWebGrid.
