ComponentOne Studio® for Silverlight Pre-release

AgDataGrid Suite for Silverlight

AgDataGrid是免费的，有源代码的哦，不过现在还下载不到。

DevExpress出品的控件，我之前用过，确实很好用；其实C1的我也用过，各有千秋。以后我会两个都试用一下。

下面是一些新特性：

• UI Framework: Beta 2 includes improvements in animation support, error handling and reporting, automation and accessibility support, keyboard input support, and general performance. This release also provides more compatibility between Silverlight and WPF.
• UI框架的加强：Beta 2 包含在动画支持、错误处理和报表，自动化和易访问性方面的支持、键盘输入的支持和常用性能方面都有所提高。这个版本也提供了在Silverlight和WPF之间更好的兼容性。
• Rich Controls: Beta 2 includes a new templating model called Visual State Manager that allows for easier templating for controls. Other features include the introduction of a TabControl, text wrapping and scrollbars for TextBox.  DataGrid additions include Autosize, Reorder, Sort, performance increases and more. Most controls are now in the runtime instead of packaged with the application.
• 丰富的控件：Beta 2包含了新的称为视觉状态管理器（Visual State Manager）的模板化模型，允许对控件进行更容易的模板化。也包含了其他的一些控件和特性：如TabControl、TextBox的文本折行和滚动条支持。DataGrid额外添加了Autosize、Reorder、Sort、性能提高等等。很多控件现在已经加入到运行时的程序集了，而不是和应用程序打包在一起了。
• Networking Support: Beta 2 includes improved Cross Domain support and security enhancements, upload support for WebClient, and duplex communications (“push” from server to Silverlight client).
• 网络支持：Beta 2包含了对跨域支持的加强和安全方面的加强，WebClient支持上传和双向同学（以及从服务器“推”数据到Silverlight客户端）
• Rich Base Class Library: Beta 2 includes improved threading abilities, LINQ-to-JSON, ADO.NET Data Services support, better support for SOAP and other improvements to make networking and data handling easier.
• 丰富的基类库：Beta 2包含了线程功能的增强，LINQ to JSOn、ADO.NET Data Services的支持，对SOAP更好的支持，以及让网络和数据处理更容易的其他增强。
• Deep Zoom: Beta 2 introduces a new XML-based file format for Deep Zoom image tiles as well as a new MultiScaleTileSource that enables existing tile databases to utilize Deep Zoom. Better, event driven notification for zoom/pan state is another improvement in Silverlight 2 Beta 2.
• Deep Zoom更好的支持：Beta 2引入了针对Deep Zoom图像块的基于XML的文件格式，以及一个新的MultiScaleTileSource对象来实现把现存的图片块数据库转换为Deep Zoom。针对缩放更好的，事件驱动的提醒是Silvelight 2 Beta 2中的有一个增强。
