Answer 1

Please read Displaying grouped data it shows how to manipulate group data
also read Grouping object “a collection of grouped data”

The Grouping class defines the fields in the data provider of the AdvancedDataGrid control used to group data

In pasted code t.currentItem contains group specific collection under Repeater control

Hopes that helps
