Group on calculated value

rbuser

Hi,

I want to define a group based on a calculated value.

I did the following

Define a group with breakType = btCustomField and
BreakName = periodBreak which is the name of a TppVariable of DataType =
dtString.

Then on the "oncalc" event of the variable, I set its value to something
representing the group identifier.

I put the variable in the detail band and I can see the good values
appearing but the group break does not happen. All the records are listed in
the same group even though the BreakValue changes.


What's wrong with my approach ?

Tks for help

Use the OnGetText event. This is the only time we ever say to use any event
other than OnCalc with a variable:) The reason is that referencing the Text
property triggers the OnGetText event. This is fired when the group asks for
the group break value from the variable. This also happens before the report
engine tells the OnCalcs to fire, because the engine has to know if it is
going to start a new group or not.
