Examples

The following example creates a form that prompts the user to edit an existing item. If the user submits the form, the example calls CommitEdit to save the changes to the collection. If the user cancels the form, the example calls CancelEdit to discard the changes. For the entire sample, see Changing a Collection by Using IEditableCollectionView Sample.

IEditableCollectionView editableCollectionView =
            itemsControl.Items as IEditableCollectionView;

// Create a window that prompts the user to edit an item.
ChangeItemWindow win = new ChangeItemWindow();
editableCollectionView.EditItem(itemsControl.SelectedItem);
win.DataContext = itemsControl.SelectedItem;

// If the user submits the new item, commit the changes.
// If the user cancels the edits, discard the changes. 
if ((bool)win.ShowDialog())
{
    editableCollectionView.CommitEdit();
}
else
{
    // If the objects in the collection can discard pending 
    // changes, calling IEditableCollectionView.CancelEdit
    // will revert the changes. Otherwise, you must provide
    // your own logic to revert the changes in the object.
    
    if (!editableCollectionView.CanCancelEdit)
    {
        // Provide logic to revert changes.
    }

    editableCollectionView.CancelEdit();
}

Dim editableCollectionView As IEditableCollectionView = TryCast(itemsControl.Items, IEditableCollectionView)

' Create a window that prompts the user to edit an item.
Dim win As New ChangeItemWindow()
editableCollectionView.EditItem(itemsControl.SelectedItem)
win.DataContext = itemsControl.SelectedItem

' If the user submits the new item, commit the changes.
' If the user cancels the edits, discard the changes. 
If CBool(win.ShowDialog()) Then
    editableCollectionView.CommitEdit()
Else
    ' If the objects in the collection can discard pending 
    ' changes, calling IEditableCollectionView.CancelEdit
    ' will revert the changes. Otherwise, you must provide
    ' your own logic to revert the changes in the object.

    If Not editableCollectionView.CanCancelEdit Then
        ' Provide logic to revert changes.
    End If

    editableCollectionView.CancelEdit()
End If
