I have AdvancedDataGrid with multi level GroupingCollection2 which shows 1000s of rows.
I am using displayItemsExpanded="true".
Is there a way not to expand it not all the way up, but to the particular level of grouping,
lets say to level 1 programmatically ?
So in that case user will see 100s of 1st level groups (each having 5-10 rows inside).
That makes a lot of sense and convenient to users.
How can I do that?
Using Flex 4.5.1 with Flex3 ADG.
