Double click functionality in Webdynpro ABAP ALV

Hello!

I have web dynpro application with ALV Table.

I need to reproduce the standard R/3 functionality: after the double clicking on the table row the new window with content of that row's fields should appear in the form layout .

For example, such functionality we have in the RSDMD transaction.

So I have two questions:

1. How to catch double click in the alv table of the Web dynpro application;

2. How to represent information from the alv table row in the form layout?

Could you please help me?

Thanks,

Mariya
