Adding DataSet columns at runtime

jameskoch

Is it possible to add columns (preferably computed ones) to a regular DataSet at runtime using DataSetEventAdapter?

I'm fairly certain I can accomplish this by using a ScriptedDataSet to add some columns at runtime, but I'd rather leverage an existing ODA DataSet.

If this is possible, are there any samples around? I'm a bit of a newb.

After several hrs of experimentation, I can begin to answer my own question, in case it helps others.

I've had the best luck w/ this by avoiding a DataSetEventAdapter and instead adding a new ComputedColumn using a ReportEventAdapter's beforeFactory method. The code is very simple, it just took me a long time to figure out that it needed to be in this method.

Dynamically adding this item to an existing Table on a report is another requirement of mine, and a bit trickier, but I seem to have it working thanks to a co-worker's diligence. No point in discussing that here unless others have questions.
