Regarding Interactive list in alv

Question

Hi Experts,
I want to know how to do a inteactive report in alv.
For example: First i will display a alv list. Then when i double click on a field of a line or click on button (Details) by selecting  a line ,  then it will navigate me to the alv list with corresponding records where i clicked previously.
How to use buttons in this case as we r using in simple interactive report.
Can anyone pls help me in creating a simple example for the above???
Thanks
