How to change the group of a card when a property in an object has been changed.
To achieve this requirement you can use a QueryableCollectionView as the ItemsSource of RadCardView. Then on data item property changed, reset the GroupDescriptors of the collection view.
{{region cs-kb-cardview-fix-group-changes}} private void UpdateItem() { var qcv = (QueryableCollectionView)this.cardView.ItemsSource; var dataItem = (Person)qcv[0]; dataItem.GroupKeyProperty = "new group value"; qcv.GroupDescriptors.Reset(); } {{endregion}}
