Hello experts,
When I edit a row in my GridView, the EditIndex always shows -1 in my gvBonuses_RowDataBound event. Can anyone tell me why this is happening? Gridview code is below:

            <asp:GridView ID="gvBonuses" ValidationGroup="Edit" runat="server" AutoGenerateColumns="False" 
                DataKeyNames="id" DataSourceID="sdsBonuses" CssClass="mGrid" 
            OnRowDeleting="gvBonuses_RowDeleting" OnRowUpdated="gvBonuses_RowUpdated" 
            OnRowEditing="gvBonuses_RowEditing" OnRowDeleted="gvBonuses_RowDeleted" 
            OnRowUpdating="gvBonuses_RowUpdating" OnRowDataBound="gvBonuses_RowDataBound"
            >
                <Columns>
                    <asp:CommandField ShowEditButton="True" ValidationGroup="Edit" CausesValidation="true"/>
                    <asp:BoundField DataField="id" ReadOnly="True" Visible="false" />
                    <asp:BoundField DataField="employee_id" HeaderText="Employee ID" ReadOnly="True"

                    <asp:BoundField DataField="name" HeaderText="Payee Name" ReadOnly="True"
