If you use a linked data source for your fancy page, but need to only show "current items", you need to manually edit the SelectCommand CAML attribute of the SharePoint:SPDataSource node for the relevant list:
<View>
<Query>
<Where>
<Gt>
<FieldRef Name="EventDate" Type="DateTime"/>
<Value Type="DateTime">
<Today OffsetDays="-7"/>
</Value>
</Gt>
</Where>
</Query>
</View>
OffsetDays allows you to specify an offset from Today. In this case it is one week in the past (to show recently "expired" items). Don't forget to htmlencode it!
