ALV- making row editable.

Hi all.

In my application, i have an ALV table displayed.

I have a button, say change. When the user selects a particular row and clicks the button, i want the entire row to be editable.

I tried using a seperate attribute and then binding the read only property. But, it seems i am going wrong somewhere.

I am fine with making an entire column or entire table editable, but a single row is a problem.

Please suggest. Sample code , if possible, is welcome.

thanks,

Prati.
