update all currently showing records

[webcat]

hi all,

how about this?


I want to allow users to click a check box on a form to 'flag for testing'
thats fine - works great

but
what if there is 100 records and the user wants to flag ALL of them for testing?

how can i have a checkbox that basically 'selects all'

however, the 'all' must only be the currently returned records, there could be lots of filters currently active...

how do i know what the currently showing records are?


thanks for any info.!
