Property Value

Differences in between the network state before and after an edit.

Changes to the networks state for a feature are only reported if the feeder information for a feature has chaged.

Finding loops created by the edit which triggered a feeder changed event.

{
    IEnumerable<string> editingFeedback = GetEditingFeedback(e.Diffs);
            
    if (editingFeedback.Any())

        MessageBox.Show(warnings);
    }

    int deenergizedFeatureCount = diffs.Count(diff => diff.InfoAfter.EnergizedPhases == Phases.None);
            
        if (deenergizedFeatureCount > 0)
    {
        warnings.Add(string.Format("Warning {0} features were de-energized as a result of the previous edit.", deenergizedFeatureCount));
    }
            
    if (diffs.Any(diff => diff.InfoAfter.FeederIDs.Count() > 1))
