'Declaration
 
Public Function New( _
   ByVal collectionView As DataGridCollectionViewBase, _
   ByVal newItem As Object, _
   ByVal cancel As Boolean _
)

'Usage
 
Dim collectionView As DataGridCollectionViewBase
Dim newItem As Object
Dim cancel As Boolean
 
Dim instance As New DataGridCreatingNewItemEventArgs(collectionView, newItem, cancel)

public DataGridCreatingNewItemEventArgs( 
   DataGridCollectionViewBase collectionView,
   object newItem,
   bool cancel
)

Parameters

collectionView

The DataGridCollectionView to which the item will potentially be added.

newItem

The new item to add to the collectionView. Will be a null reference (Nothing in Visual Basic) by default  (see Remarks).

cancel

true to cancel the creation of the new item; false to let the process continue.

If the insertion of new items is to be handled manually, a new item must be provided and the Handled property set to true to indicate that the process will be handled manually. If a new item is provided but the Handled property was not set or was set to false, the item will be ignored and a new item will be created by the DataGridCollectionView (if possible). An InvalidOperationException will be thrown if the Handled property is set to true but a new item is not provided.

If a new item is not provided and the event is not handled, an attempt will be made by the DataGridCollectionView to create a new item.
