NextIsNull
Hi,
One of my tasks is porting Crystal Reports to RBuilder.
In general, rather simple, but the reports contain NextIsNull - reference to the next record.
Currently, the only solution I can imagine - copy the dataset into a ClientDataSet and add info about the next record during copying.
Not very hard performance because the datasets after filtering is rather small.
However, I do not like this solution.
I wonder whether anybody knows something better?
Thank you,
Mahris

ReportBuilder does not have built-in NextIsNull functionality. One option
may be to keep a second dataset, identical to the one connected to the
report traversing along with it. Then when you need to know if the next
record is null, you can skip ahead of the current location and test the
field.
