ASYNC and selection

I've created a grid with a checkbox type in the first column.  I then added a button elsewhere on the form that has an ASYNC event.  In that ASYNC event, I report back the selected rows. However, the selections do not register (there appear to be no selections) unless I change pages first.  If I do the same process with a full postback, there is no problem.

 
thoughts?
 
Thanks,

I have not been able to reproduce this issue.

Are you using grid.RowSelect[RowIndex] to retrieve the selected rows?

If the problem persists, please provide a ready to run sample project (through mailto:info@tmssoftware.com) that demonstrates the issue so I can further investigate this issue.
