Question

I am working on wicket. I used a checkbox for every row in a table which is generated through Listview. I want to delete a particular row by using checkbox selection.

This table can be generated by using Listview which shows table data. Please tell me at least how I would get the row id by selection of multiple checkboxes. Please tell me how could I do this?
