DATA / calcs expression

rbuser

I am trying to alter the contents of an Data/Calcs expression field within
and am having a spot of trouble..

Is there a way to name the "Field Alias" of an ISQLBuilder.Calcfields
value ??

I am trying to allow the "user" to manually enter a post code, then try
and change my default calcs expression to what they enter by using a
string replace or similar.

Hi Steven,

Looking at the code, it looks like you can get access to the Items property
of the Calcfields list which returns a TdaCalculation object. It does not
however look like this (or the TdaField) class is exposed to RAP so you
would either need to create a pass-thru function or create and register your
own RTTI class exposing the TdaField published properties.

I will add this as a possible enhancement for the next release of
ReportBuilder.

Well, thats good news that you can forward enhancements. The other reason
I needed this was because I wanted the calcs expression field alias to
appear in my CROSSTAB report, as it shows the Alias. Thanks though, I will
have to look at another way of creating my Calcs expression. I will
probably just use a DECLARATION field and my Users can change instead.

Thanks Nico.
Steven
