'Declaration Public ReadOnly Property Rows As RowsCollection
public RowsCollection Rows {get;}
There are two row filtering modes: SiblingRowsOnly and AllRowsInBand. When it's AllRowsInBand all the rows in a band are being filtered and thus there is no particular rows collection that's being filtered. As a result this property returns null. However if the row filter mode is SiblingRowsOnly where rows of a particular rows collection are being filtered, then this property will return that rows collection.
