 Hi there,
 
 I need to sort the advanced grid but I want the sort apply only 
 certain nodes of data. For example Group 0 contains 10 items which it 
 makes sense to sort while Group 1 contain items which should always 
 remain in the same sequence. The sequence should not even change if 
 the sort changes from ascending to descending. In other words, the 
 sort should only affect certain groups of data.
 
 From the docs, it looks like the sortCompareFunction cannot 
accomplish 
 this since it does not expose the characteristics of the current sort 
 - it just determines the sequence of two elements.

AdvancedDateGrid casts its dataProvider to HierarchicalCollectionView, 
which means that if you have any node you know what its parent is.  
sortCompare tells you what the node is.

HTH;

Thanks Amy! This is helpful - I will play with this and try to make it 
work.
