Intersoft ClientUI 6 adds over 30 new controls to its already comprehensive tools portfolio for the Silverlight and WPF application development. ClientUI 6 is strongly focused in providing advanced line-of-business controls, ranging from powerful schedule views, lookup box, data combobox, to SQL report viewer and Office-2010 style ribbon.

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.


Event Aggregator

ClientUI now includes a built-in event aggregator in ClientUI Framework. Event aggregator is an advanced event manager that facilitates the decoupling of publisher and subscribers messaging between different part of applications. It channels events from multiple objects into a single object to simplify registration for clients. Event aggregator is an ideal pattern for applications built with MVVM pattern due to its loosely-coupling messaging capability. For more information, see Event Aggregator Overview.

Flow Document Framework

In the previous version, ClientUI added a powerful document framework which enables you to create a single content that can be consistently viewed in both Silverlight and WPF applications. In this release, ClientUI advances the document framework further by adding a sophisticated flow document library. Flow document implements comprehensive rendering and layout specification similar to those in Microsoft Word. For more information, see Flow Document Framework Overview.

Enhancements to Existing Controls

Enhanced Popup

UXPopup now supports nested popup scenario to easily achieve certain UI design requirements. In addition, it also introduces a new modal feature which enables the popup to remain visible with the input events captured to the child popup. To enable this feature, set the IsModal property of the UXPopup to true.

Enhanced Busy Indicator

UXBusyIndicator now introduces DisableContentOnBusy property which you can specify to determine whether the content should be disabled when busy. In the previous release, this behavior is automatic based on the value in BlockUIOnBusy property. Setting the DisableContentOnBusy property value to false might improve performance when the content includes many controls that use commanding. To learn more about commanding, see Commanding Overview.

Improved Memory Management

All existing ClientUI controls have been enhanced with an improved memory management. This means that virtual content controls such as UXPopup and UXContextMenu are now automatically removed from the global handlers instead of waiting the system to dispose the instances, when they are no longer referenced or the owner of the controls have been removed from the visual tree. Consequently, the complex controls that consume these virtual content controls will also perform faster with better resources management.

In addition, the UXFrame and UXPage which serves as the fundamental navigation components have also been significantly improved with resource-efficient navigation processing. To learn more about ClientUI navigation framework, see Navigation Overview.

Integration with IdeaBlade DevForce

Since the previous release, Intersoft ClientUI installer has included IdeaBlade DevForce as part of the installation process. The integration enables streamlined development of cross-platform data applications in an end-to-end approach, from the view (UI) design to the entity modeling and data services. For more information about the integration features, see ClientUI 5 Release Notes.

In this release, ClientUI ships more data controls and new project templates that work with DevForce such as UXScheduleView. To get started with UXScheduleView and DevForce, see Walkthrough: Bind UXScheduleView to DevForce Services Using MVVM Pattern.

DevForce Version Update

ClientUI 6 now automatically install the most recent DevForce release, version For more information about the changes in DevForce, please read DevForce Release Notes.

Update in Intersoft.Client.Data.Provider.DevForce

DevForce version includes several new features such as Code First support and significant enhancements to the LINQ and paging capability. In this release, the ClientUI data provider for DevForce has been updated to take advantage of the new paging API introduced in DevForce 6.1.3. As the results, a new extension for ExecuteAsync method is added to let you easily working with paged data using QueryDescriptor.

The following code shows the differences between the previous paging approach (DevForce 6.0.9+) and the new paging approach (DevForce




If you prefer, you can still use the old paging code where the QueryDescriptor is parsed first before ExecuteAsync is called, however, it will not leverage the enhancements and the new paging API available in DevForce 6.1.3.

ClientUI and DevForce Business Application Project Template

In the initial release, ClientUI shipped with MVVM Business Application project template that uses WCF RIA Services as the data service provider. Starting from this release, ClientUI includes a separate version of business application project template that uses DevForce as the data service provider.
