Hi,

I've got a page with one Placeholder on it and nothing else. I've added the RadScriptManager and the RadGrid using the code below and the Paging works ok but the sorting doesn't?  No error is thrown. It shows the sorting icons in the column heading but does not actually do the sorting.

If I do exaclty the same using the Designer pages it all works fine. It's trying to do things programmatically that I can't get it to work.
