View

Purpose

This module provides WPF view components for graph list functionality, specifically for displaying and exporting graphs. Both views implement a pattern of suppressing the ApplicationCommands.Undo command by adding a CommandBinding that marks the command as handled. This prevents undo operations from propagating in these views.

Public Interface

ExportGraphMainView (implements IExportGraphMainView)

• ExportGraphMainView() - Constructor that calls InitializeComponent() and adds a CommandBinding for ApplicationCommands.Undo. Both the Execute and CanExecute handlers set e.Handled = true with no other action.

GraphMainView (implements IGraphMainView)

• GraphMainView() - Constructor that calls InitializeComponent() and adds a CommandBinding for ApplicationCommands.Undo. Both the Execute and CanExecute handlers set e.Handled = true. Contains commented-out code for focusing TvTestChannels and checking root.IsChecked.

Invariants

• Both views unconditionally suppress ApplicationCommands.Undo by handling it without action.
• The CanExecute handler does not set e.CanExecute, only e.Handled.

Dependencies

Depends on:

• DTS.Common.Interface (IExportGraphMainView, IGraphMainView)
• System.Windows.Input (CommandBinding, ApplicationCommands)

Depended on by: Not determinable from source alone.

Gotchas

• Undo suppression pattern: Both views suppress undo without any conditional logic. This may interfere with expected user behavior if undo is needed elsewhere in the application.
• Commented-out code in GraphMainView: References to root.IsChecked and TvTestChannels.Focus() suggest incomplete or removed functionality.
• Namespace suppression: ReSharper disable comments indicate potential namespace convention violations.
