All the changed record in webdynpro alv

Hi Experts,

I have a requirement to get all the changed records in alv (on press of an enter), I have used the alv events which gives me only the selected record index But i need to get all the records a user has changed before pressing enter key.

I tried the context log, but it gives me log only of my component's context. It doesnt give the changes done in alv.

Please help

Thanks & Regards,

Tashi
