with paging on a datagrid. The first page works fine when I want to get the datakeyfield value. But all subsequent pages I get the value of 0. Anyone know why this happens, and is there anything I can do about it? (I even get a zero when accessing a hidden databound column, so that option is out too)

Could you provide some relevant code samples so we can see what you are doing? (please don't just paste the whole page of code, just what's applicable.)
