IDO Extension Class Events - PreLoadCollection and PostLoadCollection?

Legacy Contributor

Looking to see if anyone has any experience using the IDO Extension Class Events, PreLoadCollection or PostLoadCollection, to alter the IDO Collection sent back to the client? Code examples would be awesome.

These are .NET event handlers you implement in the IDO Class Extension code, and when you run code in the client that causes a LoadCollection action against the IDO the IDO Extension Class is attached to, it is supposed to fire these events and allow you to return a custom result set. I spent all day trying to follow the documentation to test out how it works, but haven't had any success.

Thanks in advance,

Tim

So... I finally go this to work. As usual, the Infor documentation was wrong. You use the PostLoadCollection event to update the data returned to the client. A sample of the code I created for the SLOrderInvoicingCreditMemoReport report is attached. Basically this updates an IDO Property added to an extended version of the standard report IDO with the Product Code from the SLItems IDO for the item on each invoice line. In a nutshell, the steps are:

1. Create an extended version of the report IDO
2. Add new unbound IDO Properties for the new fields you want to add to the report
3. Copy the IDO Method for the standard report to new IDO Method
4. Add the new IDO Properties to the output property list of the new IDO Method
5. Develop your IDO Extension Class with code that iterates through the data and updates the new IDO properties with the values you want them to have
6. Add the IDO Extension Class to your extended IDO
7. Modify (or copy and modify) the report form and point it to the new IDO and IDO Method
8. Add the new IDO properties to the report

The code attached is just the IDO Extension Class which shows how to do step #5.

It's a pretty cumbersome process to just add a couple fields, but necessary when you have a report procedure like the Order Invoice that you can't EXTGEN.

Infor could make this a whole lot easier by making it so you can just use a DataView for the basis of a Form Report.
