示例1: AddTracks
private void AddTracks(List<ITrack> tracks, ReadOnlyObservableCollection<object> group)
{
if (group.Any())
if (group[0] is ITrack)
tracks.AddRange(group.Cast<ITrack>());
else
foreach (CollectionViewGroup item in group)
AddTracks(tracks, item.Items);
}示例2: UpdateErrorsAndHasErrors
// this helper sets properties and raises events in the same order as System.Controls.Validation
private static void UpdateErrorsAndHasErrors(
DependencyObject dependencyObject,
IEnumerable<ValidationError> removedErrors,
IEnumerable<ValidationError> addedErrors,
ReadOnlyObservableCollection<ValidationError> errors)
{
if (errors.Any())
{
SetErrors(dependencyObject, errors);
SetHasError(dependencyObject, true);
}
else
{
SetHasError(dependencyObject, false);
SetErrors(dependencyObject, ErrorCollection.EmptyValidationErrors);
}
// ReSharper disable PossibleMultipleEnumeration
var removed = removedErrors.Except(addedErrors).AsReadOnly();
var added = addedErrors.Except(removedErrors).AsReadOnly();
if (added.Count == 0 && removed.Count == 0)
{
return;
}
dependencyObject.UpdateParent(removed, added);
(dependencyObject as UIElement)?.RaiseEvent(new ErrorsChangedEventArgs(removed, added));
(dependencyObject as ContentElement)?.RaiseEvent(new ErrorsChangedEventArgs(removed, added));
foreach (var error in removed)
{
(dependencyObject as UIElement)?.RaiseEvent(new ScopeValidationErrorEventArgs(error, ValidationErrorEventAction.Removed));
(dependencyObject as ContentElement)?.RaiseEvent(new ScopeValidationErrorEventArgs(error, ValidationErrorEventAction.Removed));
}
foreach (var error in added)
{
(dependencyObject as UIElement)?.RaiseEvent(new ScopeValidationErrorEventArgs(error, ValidationErrorEventAction.Added));
(dependencyObject as ContentElement)?.RaiseEvent(new ScopeValidationErrorEventArgs(error, ValidationErrorEventAction.Added));
}
// ReSharper restore PossibleMultipleEnumeration
