I am modifying an ASPX page and it needs a bit of AJAX to improve the user experience. I'm trying to add a couple calendar extenders and move a datagrid into an update panel.
But without those components even being added, the presence of the ScriptManager causes IE to show the "Done, but with errors on page" icon. Double-clicking it shows:
Error: 'Sys' is undefined
If I do include the AJAX controls, they don't work.
Any ideas on this?
