GridView.DataKeys appear not to be filled

[sevilsivle]

Hi,

I've set up the DataKeyNames attribute for my GridView gridBlackList which
is contained on a control. When I request the gridBlackList.DataKeys on the
PageIndexChanged event, the DataKeys array appears to be empty. However, when
I put a breakpoint on the Page_Load of the control the DataKeys array seems
to be filled out correctly.

Does anyone hav ea clue of what is going on?

Thanks in advance,
Greetings,
Casper
