Automatically refresh ICollectionView Filter

Question

Is there any way to automatically update a filter on an ICollectionView without having to call Refresh() when a relevant change has been made?

Answer 1

For .Net 4.5: There is a new interface which can help to achieve this feature, called : ICollectionViewLiveShaping.

From MSDN link:

When live sorting, grouping, or filtering is enabled, a CollectionView will rearrange the position of data in the CollectionView when the data is modified. For example, suppose that an application uses a DataGrid to list stocks in a stock market and the stocks are sorted by stock value. If live sorting is enabled on the stocks' CollectionView, a stock's position in the DataGrid moves when the value of the stock becomes greater or less than another stock's value.
