Pass a Value when delete button is clicked

Question

I have a delete button on a gridview for each row that calls gvSiteInfo_RowDeleting(object sender, EventArgs e) when it is clicked. How do I find out the value of the row number of the clicked delete button? I need to have the row number in the delete method where i specify with << NEED ROW NUMBER HERE!! >>

So far I haven't been able to turn up anything searching the web and when i print out the values of sender and e they don't tell me anything useful.

 protected void gvSiteInfo_RowDeleting(object sender, EventArgs e)
    {

        SiteDB site = new SiteDB();
        site.SelectedConnectionString = "SQLDEV08";
        site.deleteSite(<<<NEED ROW NUMBER HERE!!>>>);
    }

<asp:GridView ID="gvSiteInfo" runat="server" AutoGenerateColumns="False" OnSorting="gvSiteInfo_Sorting" width="100%"
    AllowSorting="True" OnRowDeleting="gvSiteInfo_RowDeleting" >
    <Columns>
        <asp:CommandField ButtonType="Button" ShowDeleteButton="True" ShowCancelButton="True" />
        <asp:BoundField DataField="prodServer" HeaderText="Production Server" 
            SortExpression="prodServer" />
        <asp:BoundField DataField="prodIP" HeaderText="Production IP Address" 
            SortExpression="prodIP" />
        <asp:BoundField DataField="Priority" HeaderText="Priority" 
            SortExpression="Priority" />
        <asp:BoundField DataField="Platform" HeaderText="Platform" 
            SortExpression="Platform" />
    </Columns>
</asp:GridView>

The RowDeleting event actually takes GridViewDeleteEventArgs, not your standard EventArgs. There is a RowIndex property on the former that will give you the index of the row being deleted.
