Intersoft ClientUI 7 adds a lightweight IoC container and a powerful view extensibility to the ClientUI Framework, as well as several new innovative data controls designed to address large data scenarios in line-of-business application development. The new release also adds significant enhancements to the existing controls as well as new framework features across Silverlight 3, Silverlight and WPF platforms.

This topic contains the following sections.

Framework

New: Inversion-of-Control (IoC) Container

ClientUI now includes a robust and lightweight IoC Container in ClientUI Framework. Inversion-of-Control (IoC) is a design pattern that inverts the flow of the application logic, which is achieved through the use of Dependency Injection for its binding process. The goal of this design pattern is to achieve maximum loose coupling where dependencies can be minimized or completely eliminated. With this approach, the application code can be easily extended as the concrete implementation can be dynamically specified or changed at runtime. For more information, see Inversion-of-Control (IoC) Container Overview.

New: Region Manager for View Extensibility

In this release, ClientUI has provided the most comprehensive design pattern library for Silverlight and WPF application development, from Application Modularity, MVVM, Event Aggregrator, to IoC Container and Region Manager. The new Region Manager library provides the design patterns for extending views in loose coupling approach. It supports two of the most common approaches to view extensibility such as View Injection and View Discovery. For more information, see Region Manager Overview.

Enhanced: Application Framework

The following list details the enhancements made to the ClientUI Application Framework:

  • Added the Download method overload with event argument in the OnSuccess parameter.

     

    C#
  • Bootstrapper support through the provided IApplicationInitializer interface. This feature works consistently in root application (shell) as well as in on-demand loaded XAP package. In addition, it works in conjunction with the IoC Container where container registration is required when the application is first loaded into the domain.
  • Added RemoveSetting method to remove a setting from the isolated storage in the application scope.
  • Added WindowClosing event to the Browser class. This feature allows you to show confirmation window before the browser is closed or navigated away which is useful in business applications with editing form. Furthermore, it doesn’t require any additional code in the plug-in host/page.

    The following code example shows how to implement the event to show confirmation dialog when the browser window is closed.

     

    C#

     

    The browser’s confirmation dialog will only appear when the ShowConfirmationDialog property of the event argument is set to true. You can customize the message through the provided Message property.
     
  • Added DisableSilverlightContextMenu static property to the Mouse class, enabling the native Silverlight context menu to be disabled globally.

For more information about ClientUI Application Framework, see Application Framework Overview.

Enhanced: Navigation Framework

The following list details the enhancements made to the ClientUI Navigation Framework:

  • Supports extra data passing during navigation through the ExtraData property in the NavigationOptions class which is commonly set to the command parameter using MVVM pattern.
  • Added Authenticating event to the UXFrame to provide you with a more granular control over the authentication process, i.e., implementing your own authentication logic.

For more information about ClientUI Navigation Framework, see Navigation Overview.

Enhanced: Localization Manager

  • Added SetUICulture method to change only the UICulture without modifying the default thread's culture. 

For more information about localization, see Localization Overview.

Enhanced: JsonSerializer

New Controls

  • Added NewRowPosition property to change the new row position. You can change the new row position to bottom when EmptyRowsVisibility is set to Visible.
  • Added NewRowLostFocusAction property to determine the behavior when you lost focus when editing a new row.
  • Added LostFocusAction property to determine the behavior when you lost focus when editing a row.

For the information about UXGridView and its complete features, see UXGridView Overview

UXWindow & UXWindowChrome

  • Added InnerBorderThickness property to control the thickness of the inner border element.

UXDialogBox

  • Added AutoCloseDialog feature. When set to true, it will automatically close the dialog when a value is assigned to the DialogResult property. This feature is useful in MVVM scenario when the DialogResult property is bound to the ViewModel and its value is changed in the ViewModel.

UXMessageBox
