Point in Polygon Selection

I have a Polygon Layer and a Point Layer. I would like to know if these tasks are able to be done in the Flex Viewer? and can someone explain to me how to do this, or at least point me in the right direction?

TASK 1
Is there a way when I select a polygon from the Search Widget to have it select all the points that fall inside that polygon?

TASK 2
With the points inside the polygon selected, export these records to an Excel Spreadsheet.

thanks.
