Read from Secondary Data Source Repeating Section

Hi All,

I have a repeating section on an InfoPath form. This is populated via a Secondary Data source (MSSQL) and works well.

I have some fields in the repeating section that I would like the user to be able to edit, and ultimately save back to the MSSQL DB.

I am successfully able to update the DB (the final step), however I am stuck getting the data from the repeating section.

Can anybody assist with how to loop through the controls on the repeating section when it is bound to a Secondary Data Source?

I am using Sharepoint, InfoPath 2013 and C# and the form is web-enabled.

Thanks,

Nathan
