[Solved] Get group total on calculated column sum

[Felice]

I have this Radgrid where I use a calculated column "column" to get the total value per row. I use a calculated column because the two items "Quantity" and "Cost" come from different db tables.

<MasterTableView CommandItemDisplay="Top" DataKeyNames="Id" DataSourceID="SqlDataSource1" PageSize="3000" GroupsDefaultExpanded="false">
                                <GroupByExpressions>

                                <EditFormSettings>
                                    <FormStyle BackColor="Yellow" />
                                    <EditColumn UniqueName="EditCommandColumn1" FilterControlAltText="Filter EditCommandColumn1 column"></EditColumn>
                                </EditFormSettings>

                            </MasterTableView>

I am experiencing problem in getting the total value of each Group aggregated as sum in the group header. I have checked the documentation but still I am unable to get it. I would really appreciate if someone here can support me with an example based on the above grid. Thanks a lot,
Felice
