Detecting a datagrid pageIndexChanged event in page_load

[Guest]

Hi,

I have a web page with a datagrid wich shows a view on miltidimensional data from analysis server. I want to restrict the data access by not repopulating my datasource when changing page. I can't restrict this by not performing the data access on postbacks, as the postback may well be a request to drilldown through the data and require re-populating the grid. Ideally I would like to check for a datagrid pageIndexChanged event in the page_load, but any suggestions will be appreciated.

TIA

Mike
