Hello,

 You can define your own custom footer similar to this demo.

My Case Is Different.
my Total field is calculated through IValueConverter and i want its sum in the footer. but here no such case is discussed.

<telerik:GridViewDataColumn IsReadOnly="True" Width="120" DataMemberBinding="{Binding Path=., Converter={StaticResource TotalConverter}}" Header="Total">

thisis my Xaml. so  can u help to how to calc its grand total ?

Hi,

 In your converter you can sum the result of all calculations and put this in desired column footer directly.

<telerik:GridViewDataColumn Width="120" DataMemberBinding="{Binding Path=., Converter={StaticResource ResourceKey=TotalConverter}, Mode=TwoWay}" Header="Total">
                            <telerik:GridViewDataColumn.Footer>
                                <StackPanel>
                                    <TextBlock VerticalAlignment="Center" Text="{Binding Path=.,Converter={StaticResource ResourceKey=GrandTotalConverter}, Mode=TwoWay}" />
                                </StackPanel>
                            </telerik:GridViewDataColumn.Footer>
                        </telerik:GridViewDataColumn>

here above mentioned is my code. my TotalConverter is called every time. but not the GrandTotalConverter. grandTotalConverter called only once the page get Loaded. not when i assign DataContext.
