View

Purpose

This module defines base classes for views in a WPF/Prism application. BaseWindow and BaseView provide common properties (IsDirty, HeaderInfo) that delegate to their respective DataContext interfaces, enabling consistent dirty-tracking and header display across windows and user controls.

Public Interface

BaseWindow (extends Window, implements IBaseWindow)

• public bool IsDirty { get; } — Returns true if DataContext implements IBaseWindowModel and baseWindowModel.IsDirty is true; otherwise returns false.
• public string HeaderInfo { get; } — Returns iHeaderInfoProvider.HeaderInfo if DataContext implements IHeaderInfoProvider<string>; otherwise returns string.Empty.

BaseView (extends UserControl, implements IBaseView)

• public bool IsDirty { get; } — Returns true if DataContext implements IBaseViewModel and baseViewModel.IsDirty is true; otherwise returns false.
• public string HeaderInfo { get; } — Returns headerInfoProvider.HeaderInfo if DataContext implements IHeaderInfoProvider<string>; otherwise returns string.Empty.

Invariants

• Both IsDirty and HeaderInfo properties are read-only getters with no setters.
• If DataContext is null, both properties return default values (false for IsDirty, string.Empty for HeaderInfo).
• BaseWindow.IsDirty checks for IBaseWindowModel; BaseView.IsDirty checks for IBaseViewModel — these are different interfaces.

Dependencies

• Depends on: System.Windows (Window), System.Windows.Controls (UserControl), DTS.Common.Base (interfaces IBaseWindow, IBaseView, IBaseWindowModel, IBaseViewModel, IHeaderInfoProvider<string> — inferred from usage).
• Depended on by: Unclear from source alone—likely used as base classes for specific views/windows throughout the application.

Gotchas

• Interface mismatch: BaseWindow.IsDirty checks for IBaseWindowModel while BaseView.IsDirty checks for IBaseViewModel. If a DataContext implements the wrong interface for the container type, IsDirty will incorrectly return false.
• Namespace directive: Source includes // ReSharper disable once CheckNamespace suggesting the file location may not match the declared namespace DTS.Common.Base.
