ADO DataSet not being linked

I have a report "CustomReport" that has several sub-reports that choose their records based on an ADO.NET Xml data set ("UserInformationSet").

 

There is a data table ("UserTable") on the main level report with a uniqueidentifier UserGuid and a string UserID, both properly populated.

In the same DetailSection, I import a subreport "UserInformationSectionReport", which has a the "UserTable" and "RecordTable" tables from the "UserInformationSet" table and select the records from the subreport based on the UserGuid item.

 

However, the subreport displays no data. This method of data handling worked for a prior iteration of the application that used CR. Are there certain hoops

 

Before the "CustomReport" is shown in the ReportViewer object, the data set is programmatically set to "UserInformationSet". Does a similar step have to be taken for the "UserInformationSectionReport" sub-report?

 

Guidance appreciated.
