DataGridSortCommandEventArgs Issue

[Ron]

I'm trying to sort a DataGrid and for some reason I keep
getting an error message that says the type or namespace
DataGridSortCommandEventArgs doesn't exist in system.data.
Well, news flash, it's support to according to this
http://msdn.microsoft.com/library/default.asp?
url=/library/en-
us/cpref/html/frlrfSystemWebUIWebControlsDataGridColumnClas
sSortExpressionTopic.asp. Any idea why I might be getting
this error, on this page? I can get the example listed on
that page to work, but not on the page I need it to.

Thanks!
