Answer 1

Handle the RowDataBound event.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
           //Presume that the buttonField is at 1st cell
            LinkButton link = e.Row.Cells[0].Controls[0] as LinkButton;

            if (link != null)
            {
                link.Attributes.Add("onclick", "alert('Hello');");
            }
        }
    }

Answer 2

You cannot work with ButtonField for this scenario, better check Javascript before asp:ButtonField click answered by Steve.
