objectdatasource fires automatically...

Hi there,

when you put a objectdatasource control and set the selectmethod in
the page the grid is filled immediatly after page loads.

Is there a way to fill the grid from the code-behind C# with manual
firing the object datasource? I mean I would like assigne object
datasource to a submit button and when I click the submit button that
should fire the objectdatasource and fill the grid iso automatically
when page opens....

any help would be appreciated ?

thanks
