  r.a.d.grid控件自然的支持表的分页设置，使得我们可以把数据看成小的块从而更快的装载数据和更方便的浏览数据

• 更好的滚动功能
  r.a.d.grid控件通过静态表头来实现此功能。所谓静态表头是指你滚动单元格数据时，列头行始终是可见的，如下图：





• 多行选择和区域选择
  你可以很容易的通过按下Ctrl键同时点击鼠标左键，或者用拖动鼠标选择一个区域来选择你想要选择的多行数据

• 设计时（Design-Time）支持
  r.a.d.grid控件完全支持Visual Studio .NET的设计模式，这就允许你在方便的WYSIWYG（所见即所得）环境下构造，定制，组装单元格。

• 广泛的客户端应用编程接口（API）
  r.a.d.grid控件提供一个全面广泛的客户端应用编程接口，用来实现大小调整，移动，重新排序，选择，实时的滚动列等等。

• 数据导出
  你可以很容易的将数据从r.a.d.grid控件导入到微软公司的Excel和Word中。

• 灵活的编辑功能
  r.a.d.grid控件完全支持如下两种在单元格中编辑数据的方式：




• in-place -以行的方式进行编辑

• in-forms – 产生form形式的视图来编辑数据




• 支持自定义编辑器
  用户可以用自定义的编辑器代替默认的编辑器来编辑r.a.d.grid控件中的可编辑的列(Bound column, Dropdown column, CheckBox column)，一旦建立，你就可以很容易的在其它的应用程序中重用这些定制的编辑器。

• 定制外观
  所有的r.a.d.grid控件的元素都可以通过用户来自定义其外观样式。假如你有一个分层的单元格，你可以为整个单元格设置一个外观，或者分别自定义每一个表的细节。

• 简单的移植
  r.a.d.grid控件的声明语法和微软公司的DataGrid是非常相似的，因此，从DataGrid到r.a.d.grid的移植是非常容易的。

Features:

• Cross-Browser Support
  r.a.d.grid supports the full set of features on most popular browsers like Internet Explorer, Gecko-based browsers (Mozilla Firefox, Netscape), and Opera.
  Hierarchical Structures with Many Tables
  r.a.d.grid allows presentation of related DataSets as hierarchical structures of tables. A unique feature of the component is the ability to have more than one tables in the same level of hierarchy.


• Outlook-style Grouping
  r.a.d.grid allows easily implementation of multilevel Outlook-style grouping of data from a single table. Simply drag the column header(s) to the group panel on the top to define the grouping order and hierarchy. You can also programmatically group the data using the group-by expressions.
  An unique feature is the ability for single- or multi-column sorting, while the data is grouped by two columns (e.g. group by one/two column(s) and sort by another column).


• Multi-Column Sorting
  In addition to the simple one-column sorting r.a.d.grid allows you to sort data by several columns just like in Microsoft Excel.


• Viewstate Optimization
  You can tune r.a.d.grid performance by controlling the trade-off between client-side load and speed. When working with hierarchical data, you can choose one of the three available modes for loading the detail tables:
  • ServerBind - optimum server load, viewstate and render size.
  • ServerOnDemand - minimum viewstate and render-size, maximum server load.
  • Client - minimum server load, maximum viewstate and render-size. Rich client browser functionality.


• Preserving the Grid State After Postback
  A unique feature of telerik r.a.d.grid is the ability to preserve its appearance, group-by state, sorting, current page, edit or selected state, and resizing after postbacks with minimum resource usage. This significantly improves the usability of the component.
  Column and Row Resizing r.a.d.grid supports convenient client-side column and row resizing with features like:
  • real-time resizing
  • resizing of the grid on column resizing
  • clipping of the cell content on column resizing


• Column Reordering with Drag-and-Drop
  telerik r.a.d.grid allows users to quickly reorder the columns by simply drag-and-dropping their headers.


• Rich Set of Column Types
  r.a.d.grid supports all widely used column types (Edit Command, Bound, CheckBox, Dropdown, PushButton, LinkbButton, HyperLink, ) as well as Templated columns, which give you complete freedom over the data layout and formatting.
• Paging
  r.a.d.grid natively supports table paging, which allows you to view the data into small chunks for faster loading and easier navigation.
• Scrolling with Static Headers
  r.a.d.grid enhances the simple scrolling by supporting static headers - you can scroll the grid data, while the header row always stays visible.
• Multi-Row Selection and Area Selection
  You can easily select multiple rows using Ctrl + Click or by simply dragging a range over the rows, which you want to select.
• Design-Time Support
  r.a.d.grid has full support for the design mode of Visual Studio .NET. This allows you to build, customize, and populate the grid in a convenient WYSIWYG environment.
• Extensive Client-side API
  r.a.d.grid introduces a comprehensive client-side API, which enables you to resize, move, reorder, select, scroll columns on-the-fly and much more.
• Exporting
  You can easily export the content of r.a.d.grid to Microsoft Excel and Microsoft Word.
• Flexible Editing Functionality
  r.a.d.grid fully supports two flexible methods for editing the data within the grid
  • in-place - edit controls appear into the edited row
  • in-forms - the grid generates form-like view and thus saving page space


• Custom Editors Support
  Editable columns in r.a.d.grid (Bound column, Dropdown column, CheckBox column) allow for replacing their default editors with custom ones, which gives the ability for enhanced functionality such as validation, rich-text editing, third-party controls. Once created, you can then easily re-use the custom editors for other grid implementations.
• Appearance Customization
  The appearance of all r.a.d.grid elements is fully customizable using skins. If you have a hierarchical grid, you can set a single skin for the whole grid, or customize each DetailTable separately.
• Easy and Intuitive Migration
  The declarative syntax of r.a.d.grid is quite similar to that of Microsoft DataGrid, therefore, the migration from DataGrid to r.a.d.grid is very easy and intuitive.
