Occurs when a user pulls the CollectionView down to refresh its content.
public event EventHandler PullToRefresh
The PullToRefresh event's data class is EventArgs.
You can configure the DXCollectionView so that it updates its content when a user pulls the view down from the top.
To enable this functionality, set the DXCollectionView.IsPullToRefreshEnabled property to true. Then, either handle the PullToRefresh event, or define a refresh command in a view model and bind it to the PullToRefreshCommand property.
