grid view - link button click - get primary key

I've got a breakpoint on this method (see code snippet).

Execution stops on the breakpoint at runtime.

I've been looking at values for both sender and e  (passed into the method) and I cannot find the value I am looking for.

What I want is the value for "AgentFormListID" which is the primary key for each row.

I will include below the code snippet a screenshot describing what I want.  I'll also provide markup and code behind.

   protected void gvItems_RowEditing(object sender, GridViewEditEventArgs e)
        {

        }//breakpoint on this line
