I have an advanced datagrid, with the grouping collection attached to an XMLListCollection.
I tried to perform a SummaryOperation, but always ends up getting 0 (zero) on the SummaryRow as it seems the data is being treated as string, instead of numeric.
Is there a way to force the SummaryField2 object to treat the data as numeric rather than string?
Thanks.
The older SummaryField has a summaryFunction property that does what you need. You could probably also write your own SummaryOperation that takes XML into account.
