Hello folks,

Attaching some code from one of my pages... the paging on this page used to
work just fine.... when i click next it doesnt even come anywhere near the
DataGrid1_PageIndexChanged handler... tried step by step debug... just exits
after the page_load when i try to move to the next page...
Any ideas would be appreciated....
