Is there a quick way to SumFunction?

e.g. I can use SumCount like so:
<telerikGridView:GridViewDataColumn Header="Qty" Width="40" DataMemberBinding="{Binding quantity}"
                                            <telerikGridView:GridViewDataColumn.AggregateFunctions> 
                                                <telerikData:CountFunction Caption="Count: " /> 
                                            </telerikGridView:GridViewDataColumn.AggregateFunctions> 
                                        </telerikGridView:GridViewDataColumn> 



But, for a SumFunction, it seems to crash unless I explicitly define the Sourcefield like so
                                        <telerikGridView:GridViewDataColumn Header="Amount" Width="75" DataMemberBinding="{Binding totalinc}" 
                                                                            DataFormatString="{}{0:c}"
                                            <telerikGridView:GridViewDataColumn.AggregateFunctions> 
                                                <telerikData:SumFunction SourceField="totalinc" /> 
                                            </telerikGridView:GridViewDataColumn.AggregateFunctions> 
                                        </telerikGridView:GridViewDataColumn> 



Is there a way to make the SumFunction, automatically use the source from the parent column?

Hello Alexander Sun,

I am afraid that the source field for the SumFunction is obligatory . The parent column and the source field are not dependant in any way.

Hi Alexander Sun,

A quick update :
I have talked to the team about your requirement and all found your request quite reasonable. We have decided to add some logic to the grid to automatically  set the source field to the owning column when no source field is sissified.

I believe this behavior will be available with the next internal build ( Friday ) . Internal builds are available for download in your Client.NET account.

One more time thanks for the suggestion . I have updated your Telerik points.
Sincerely yours,
Pavel Pavlov
