Documentation: DTS.Viewer.GraphList Models

1. Purpose

This module provides the data model classes for the Graph List component of the DTS Viewer application. It defines hierarchical tree structures for displaying test channels and events in WPF TreeView controls, as well as graph property objects for integration with the Xceed WPF Toolkit PropertyGrid. The models implement INotifyPropertyChanged for data binding and coordinate selection/locking state with parent ViewModels through defined interfaces.

2. Public Interface

GraphPropertyObject

Namespace: DTS.Viewer.GraphList.Model

A POCO class decorated for use with Xceed WPF Toolkit PropertyGrid.

Property	Type	Category	Access	Description
Id	int	Information	Read-only	Graph identifier
Name	string	Information	Read-only	Graph name
Description	string	Information	Read-only	Graph description
Filter	string	Parameters	Read/Write	CFC filter value; uses ItemsSource(typeof(CFCFilterItemSource))
DataFlag	string	Parameters	Read/Write	Data flag identifier
ShiftT0	double	Parameters	Read/Write	Time zero shift in milliseconds
EuMultiplier	double	Parameters	Read/Write	Engineering units multiplier
EuOffset	double	Parameters	Read/Write	Engineering units offset

---

GraphObject

Namespace: DTS.Viewer.GraphList.Model

Implements IBaseClass. Primary graph data container with synchronized property object.

Property	Type	Description
RecordId	int	Record identifier with change notification
Id	int	Graph ID; synchronizes to Property.Id on set
Name	string	Graph name; synchronizes to Property.Name on set
Description	string	Description; synchronizes to Property.Description on set
Filter	CFCFilter	Filter enum; synchronizes to Property.Filter as string
DataFlag	string	Data flag; synchronizes to Property.DataFlag
ShiftT0	double	T0 shift; synchronizes to Property.ShiftT0
EuMultiplier	double	EU multiplier; synchronizes to Property.EuMultiplier
EuOffset	double	EU offset; synchronizes to Property.EuOffset
Data	List<double>	Graph data points
Visable	bool	Visibility toggle (note: typo in property name)
Property	GraphPropertyObject	Nested property grid object

Events:

• PropertyChanged - Standard PropertyChangedEventHandler event

Methods:

• OnPropertyChanged(string propertyName) - Raises PropertyChanged event
• LoadGraphs() (private) - Contains commented-out service controller code

---

TreeViewChannels

Namespace: DTS.Viewer.GraphList

Implements IBaseModel. Root node for channel-based tree view binding.

Property	Type	Description
Name	string	Node name
Groups	ObservableCollection<TestGroup>	Child test groups; updates GroupsCount on set
GroupsCount	int	Count of groups
Path	string	File/system path
IsSaved	bool	Get-only property (always default)
IsExpanded	bool	TreeView expansion state
IsSelected	bool	TreeView selection state

---

TestGroup

Namespace: DTS.Viewer.GraphList

Implements INotifyPropertyChanged. Child node representing a test group with channels.

Property	Type	Description
Path	string	File path
DTSFile	string	Associated DTS file
Parent	IBaseViewModel	Reference to parent ViewModel; cast to IGraphMainViewModel for locking
IsLocked	bool	Lock state; calls Parent.AddLockedGroupChannels() on change
IsGraph	bool	Graph display flag
IsExpanded	bool	Expansion state
CanLock	bool	Controls whether selection is permitted
IsSelected	bool	Selection state; calls Parent.AddSelectedGroupChannels() when selected
TestName	string	Parent test name
Name	string	Group name
DisplayName	string	Display name
Channels	ObservableCollection<ITestChannel>	Child channels; updates ChannelCount on set
ChannelCount	int	Count of channels

---

TreeViewIds

Namespace: DTS.Viewer.GraphList

Implements IBaseModel. Root node for event/ID-based tree view binding.

Property	Type	Description
Parent	IBaseViewModel	Parent ViewModel; cast to IExportGraphMainViewModel
Name	string	Node name
TreeIndex	int	Index for selection range operations
EventCount	int	Count of events
Events	ObservableCollection<ITestEvent>	Child events; updates EventCount on set
Path	string	File path
IsSaved	bool	Get-only property
IsExpanded	bool	Expansion state
IsSelected	bool	Selection state with cascade to children via SetChildNodes()

Methods:

• SetChildNodes(bool isSelected) - Sets IsSelected on all child Events
• SetIsItemSelected(UIElement element, bool value) - Static attached property setter
• GetTreeViewItems(ItemsControl, bool, List<TreeViewItem>) - Static recursive TreeView item collector

Attached Properties:

• IsItemSelectedProperty - DependencyProperty registered for bool type

TestEvent

Namespace: DTS.Viewer.GraphList

Implements ITestEvent. Child node representing a test event with complex multi-select logic.

Property	Type	Description
Path	string	File path
Parent	IBaseViewModel	Parent ViewModel; cast to IExportGraphMainViewModel
IsLocked	bool	Lock state; calls Parent.AddLockedEvents() on change
IsGraph	bool	Graph display flag
IsExpanded	bool	Expansion state
CanLock	bool	Lock permission flag
IsSelected	`bool
