Documentation: DTS.Common.Interface.ISO.ExtraProperties

1. Purpose

This module defines the contract for a Model-View-ViewModel (MVVM) pattern implementation for managing a collection of "extra properties" — arbitrary key-value pairs associated with some parent entity. It provides interfaces for the view (IExtraPropertiesListView), view model (IExtraPropertiesListViewModel), and individual property items (IExtraProperty), enabling UI-agnostic management of property lists with support for selection, filtering, sorting, validation, and clipboard operations. The module appears designed for use within a larger desktop application framework (likely WPF-based) that handles ISO-related data.


2. Public Interface

IExtraPropertiesListView

Signature: public interface IExtraPropertiesListView : IBaseView

A marker interface extending IBaseView with no additional members. Represents the view abstraction for the extra properties list UI.


IExtraPropertiesListViewModel

Signature: public interface IExtraPropertiesListViewModel : IBaseViewModel

Defines the view model contract for managing a collection of extra properties.

Member Signature Description
SetPage void SetPage(IDataPROPage page) Injects a page reference, presumably for navigation or context.
SetParent void SetParent(object parent) Sets the parent object that owns these extra properties.
View IExtraPropertiesListView View { get; set; } Gets or sets the associated view instance.
CopySelected void CopySelected() Copies the currently selected properties to clipboard.
DeleteSelected void DeleteSelected() Deletes the currently selected properties from the collection.
ExtraProperties ObservableCollection<IExtraProperty> ExtraProperties { get; set; } The observable collection of extra properties bound to the UI.
SetExtraProperties void SetExtraProperties(IList<IExtraProperty> properties) Replaces the current collection with the provided list of properties.
Filter void Filter(object tag, string term) Filters the displayed properties based on a tag and search term.
Sort void Sort(object o, bool columnClick) Sorts the properties collection. Parameters suggest column-based sorting.
Validate bool Validate(ref List<string> errors) Validates the properties collection; returns true if valid, false with error messages populated in the errors list.
IsReadOnly bool IsReadOnly { get; set; } Controls whether the UI allows editing of properties.
SelectedProperties IExtraProperty[] SelectedProperties { get; } Returns an array of currently selected property items.
