特點(diǎn)：

• Silverlight技術(shù)

• 專門針對(duì)Sliverlight 4采用面向?qū)ο笤O(shè)計(jì)創(chuàng)建，用C#語(yǔ)言和XAML編寫。

• 基于一個(gè)靈活的和可擴(kuò)展的對(duì)象模型，具有模塊化和可重復(fù)使用的可視化元素。

• 該數(shù)據(jù)表格單元格是真正的Silverlight內(nèi)容控件，因此它們能夠包含任何內(nèi)容。

• 支持從右到左的文本。

• 在Blueprint版本中提供可用的完整的源代碼（C#和XAML）。

• 與Silverlight基類庫(kù)無(wú)縫集成。

• 完整的文檔完全集成到Visual Studio中。

• 包含各種VB.NET和C#實(shí)例應(yīng)用程序以便您入門。

•  在行和列上執(zhí)行完整的UI可視化，即使在分組數(shù)據(jù)時(shí)，因此僅當(dāng)前視圖中的元素被創(chuàng)建和保留，這就意味著更快的加載時(shí)間，使用更少的內(nèi)存。

•  在Visual Studio 2010和Expression Blend中的設(shè)計(jì)時(shí)支持。

• 能夠被用于MVVM和MVC設(shè)計(jì)和體系結(jié)構(gòu)模式的結(jié)合之中。

• 智能，按需要的后臺(tái)數(shù)據(jù)檢索

•  按需檢索數(shù)據(jù)（數(shù)據(jù)虛擬化）確保只有那些從服務(wù)器請(qǐng)求的記錄可見。這就大大降低了傳輸?shù)臄?shù)據(jù)量，從而增加了數(shù)據(jù)表格感知速度。還可以降低服務(wù)器的壓力。

•  這唯一的Silverlight數(shù)據(jù)表格用于以驚人的速度顯示遠(yuǎn)程數(shù)據(jù)，這要?dú)w功于其強(qiáng)大的后臺(tái)（異步）記錄檢索系統(tǒng)。

• 數(shù)據(jù)虛擬化提供了通過一個(gè)便捷的無(wú)限滾動(dòng)的滾動(dòng)條體驗(yàn)而不是典型的Web網(wǎng)格分頁(yè)界面。

•  一個(gè)精巧的設(shè)計(jì)使用了被動(dòng)式的預(yù)提取技術(shù)，它在后臺(tái)緩沖當(dāng)前被請(qǐng)求的記錄的前后記錄，因此當(dāng)向上或向下滾動(dòng)或分頁(yè)時(shí)，最終用戶能夠立即看到數(shù)據(jù)：這里不需要最終用戶等待的實(shí)時(shí)請(qǐng)求，這使得您感覺到您的應(yīng)用程序很呆滯。

• 當(dāng)數(shù)據(jù)表格是空閑時(shí)主動(dòng)預(yù)提取操作被用于保持緩存滿的狀態(tài)。

•  異步（后臺(tái)）數(shù)據(jù)請(qǐng)求保持UI在任何時(shí)間響應(yīng)請(qǐng)求。目前市場(chǎng)上沒有其它數(shù)據(jù)表格能夠做到這一點(diǎn)。

• 所有的數(shù)據(jù)表格的功能都已全部包含，因此這里沒有在功能和性能上的權(quán)衡了。

•  該數(shù)據(jù)表格支持WCF Data Services和WCF RIA Services，因此開發(fā)人員只需幾行代碼就能夠獲得該系統(tǒng)的所有的優(yōu)點(diǎn)。

• 支持幾乎任何類型的自定義數(shù)據(jù)源。

•  甚至可以提供流和其它“無(wú)限制”的源的數(shù)據(jù)虛擬化，例如論壇和博客！

• 優(yōu)化的網(wǎng)絡(luò)通信和數(shù)據(jù)源查詢

•  沒有發(fā)現(xiàn)。該數(shù)據(jù)表格不需要知道有關(guān)數(shù)據(jù)源的任何信息：總行數(shù)，分組的數(shù)量和大小，或者其它任何信息。

•  高效的查詢。使用相對(duì)查詢，因此它們?cè)诜?wù)器上執(zhí)行的更快。其結(jié)果通過數(shù)據(jù)表格的迅捷導(dǎo)航。沒有其它數(shù)據(jù)表格做到這一點(diǎn)。

•  查詢節(jié)流，這樣可以大大增強(qiáng)高負(fù)載的滾動(dòng)性能。在高負(fù)載滾動(dòng)時(shí)，查詢到的服務(wù)器不在需要的數(shù)據(jù)行是作廢的，從而大大降低了服務(wù)器負(fù)載和數(shù)據(jù)表格的CPU使用率。

Features：

• Silverlight technology
  • Object-oriented design created specifically for Silverlight 4, written in C# and XAML.
  • Based on a flexible and extensible object model, with modular and reusable visual elements.
  • The datagrid’s cells are true Silverlight content controls, so they can contain anything.
  • Supports Right-To-Left text.
  • Complete source code (C# and XAML) available in the Blueprint Edition.
  • Seamless integration with the Silverlight base class libraries.
  • Complete documentation fully integrated into Visual Studio.
  • Includes a variety of VB.NET and C# sample applications to get you started.
  • Performs full UI virtualization on both rows and columns, even when grouping data, so only elements currently in view are created and kept, meaning faster loading time, uses less memory.
  • Design-time support in Visual Studio 2010 and Expression Blend.
  • Can be used in conjunction with the MVVM and MVC design and architectural patterns. 
• Intelligent, on-demand background data retrieval
  • On-demand data retrieval (data virtualization) ensures that only records that are visible are requested from the server. This greatly reduces the amount of data to be transferred, which increases the perceived speed of the datagrid. Also reduces strain on the server.
  • The only Silverlight datagrid to display remote data blazingly fast, thanks to its powerful background (asynchronous) record retrieval system!
  • Data virtualization is presented through a convenient infinite scrolling scrollbar experience instead of the typical Web-grid paging interface.
  • An ingenius design uses passive pre-fetching in the background to cache records before and after the ones currently being requested, so when scrolling or paging up or down, the end-user instantly sees the data: there are no just-in-time requests that make the end-user wait, which makes your application feel sluggish.
  • Active pre-fetching is used to keep the cache full when the datagrid is idle.
  • Asynchronous (background) data requests keep the UI responsive at all times. No other datagrid currently on the market does this.
  • Enabled for all of the datagrid’s features, so there’s no trade-off between capabilities and performance.
  • The datagrid supports WCF Data Services and WCF RIA Services, so developers get all the advantages of this system with just a few lines of code.
  • Supports practically any type of custom data source.
  • Can even provide data virtualization for streams and other “endless” sources, such as forums and blogs!
• Optimized network communications and data source queries
  • No discovery. The datagrid doesn’t need to know anything about the data source: the total row count, the number and size of groups, or any other information.
  • Efficient queries. Uses relative queries, so they execute faster on the server. The result is that navigating through the datagrid is snappier. No other datagrid does this.
  • Query throttling, which greatly enhances heavy scrolling performance. During heavy scrolling, queries to the server for data rows that are no longer needed are voided, which reduces the server load and the datagrid’s CPU usage.
• Most compelling UI experience in Silverlight, for the Web and beyond
  • Smooth-scrolling animations
  • Animated column reordering and resizing
  • Animated group collapse/expand
  • Animated row insertion/deletion.
  • Animated drag-and-drop to create groups.
  • Fully asynchronous architecture to ensure that the UI remains responsive at all times.
  • Fully stylable, so you can adapt it to your own look.
  • Supports implicit styles, so the entire app can be styled in minutes with a couple of lines of code. Also supports explicit styles.
  • Unprecedented number of customizable elements. 100% compatible with Expression Blend.
  • Animated sticky headers smoothly push previous headers off the screen.
• Views and themes
  • A gorgeous 2D tabular view
  • Column headers support drag-and-drop column reordering, column resizing, click-to- sort, and dragging to “Group-by” row.
  • Automatically changes rows height to fit the contents of the largest cell
  • Six beautiful Silverlight themes meticulously designed by our graphical artists, with more on the way.
  • Each theme provides an alternating row style.
  • Includes the XAML source code to styles and templates, so you have a great starting point for developing your own.
• Data grouping
  • Creating, expanding, and collapsing groups is always snappy.
  • Supports UI virtualization, preserving memory and reducing load time, even when grouping.
  • Interactive “Group-by” row allows end-users to easily create and manipulate groups themselves
  • Group navigation control (quick search) for increased usability
  • True nested grouping (hierarchical, multi-level grouping) increases readability and therefore productivity.
  • Customizable group-level configurations.
  • Sticky group containers help make sure end-users don’t get lost in their data.
• Data binding
  • Supports binding to any local list, WCF Data Services Web service, WCF RIA Services Web service, or custom Web service.
  • Indicator glyphs let end-users know when virtualized data is being loaded and committed, and when there has been an error.
  • Data virtualization vastly improves performance and reduces memory usage, especially when working with large data sources.
  • Filtering (filter row) in virtualized mode, letting you combine the advantage of a data virtualization performance boost and the flexibility of filtering.
  • Fully supports Silverlight data binding
  • Can be bound directly to an array of simple types such as String, Decimal, DateTime, TimeSpan, Guid, or Primitive (e.g., SByte, Byte, Int32, etc.), and will show the value of those types in one column.
• Input validation
  • Includes built-in data validation, at the cell or row level.
  • The appearance of a cell or row when a validation error occurs can be completely styled.
  • Error display is integrated with the included themes
  • Supports local data validation (IDataErrorInfo).
  • Supports remote data (server-side) validation (INotifyDataErrorInfo).
  • Supports IEditableObject
• Rich in-place editing
  • Updates source when the cell or row exits edit mode or immediately when the cell content changes.
  • Provides events for fine-grained control over the edit process.
  • Provides programmatic control over edit mode
  • Supports many edit triggers and display conditions
  • Allows you to specify an editor for a cell being edited.
  • Cell editors can be displayed without entering edit mode
  • Single-click edit mode allows entering edit mode and activating items such as check, text, and combo boxes with one click.
  • Any portion of the grid can be made read-only.
  • Provides an insertion row object that allows for quick entry of new data.
  • Automatically selects the appropriate default editor control depending on the field data type.
  • Asynchronous editing capabilities (multi-editing).
  • Default editors for all common data types.
  • Supports creating custom cell editor controls
  • Includes a combo box editor that can be used to edit related fields.
• Included editor controls
  • All included editor controls are usable either as cell viewers / editors, or independently outside of the grid for a more flexible and uniform interface.
  • Includes these controls: CheckBox. AutoSelectTextBox. DatePicker/Calendar. ValueRangeTextBox. NumericTextBox.
  • All controls are 100% stylable and templatable
  • Combinability/modularity: Embed controls into one another to create flexible, innovative new controls.
  • The grid automatically picks the correct type depending on the data type of the column.
  • Fully visual approach: Powerful designers help make development faster and easier.
  • Extensibility: All controls can be extended to implement custom features, appearance, and behavior
• Filtering
  • Supports filter expression operations such as =, >, >=, <, <=, !=.
  • Provides a filter row object.
  • Supports programmatic filtering.
  • Supports local filtering.
  • Provides Excel-like end-user automatic filtering
• Fully asynchronous architecture
  • Designed from the ground up to take full advantage of background operations to make sure the datagrid, and therefore the application, remains responsive at all times.

  • Programmatic selection: also provides examples of code behind predefined selections.
  • Selection is asynchronous.
  • Supports placing objects into fixed headers and footers.
  • Supports drag-and-drop column reordering and column resizing.
  • Full keyboard navigation is possible through cells and rows.
