  • QueryableCollectionView now responds correctly on CollectionChanged events
  • When clearing the text of a field filter text-box and applying the filters, the EventArgs of the following Filtering and Filtered events should not contain anything in their Added property.
  • Deleting the text from a filtering text-box when the column type is numeric inserts a zero instead of leaving the text-box empty.
  • When RadComboBox is used as edit template null value is set after edit
  • Null reference exception when TAB on grid and there is no current cell
  • When a distinct value is checked/unchecked from the filtering UI and the Filtering event is cancelled, it does not return to its previous state.
