Combine the grid's built-in AJAX capability with paging to allow changing the grid's displayed page without posting back.
AJAX Paging
Data can be sent to the client as XML, on demand, and rendered by the WebGrid using XSLT.  This increases performance, and allows the WebGrid to render a nearly-unlimited number of rows without performance degradation.  Many operations, including sorting, paging, and row additions, can be done with the WebGrid on the client, eliminating the need for postbacks.
AJAX Performance
Display a button in a cell under several situations, including cell activation, row activation, mouse-over cell, and more.  Respond to the click of such a cell button in client-side code, server-side code, or both.
Cell Button
Configure the grid to automatically merge together multiple cells in the same column that contain the same value. You can also merge adjacent cells manually by using the cells' properties.
Cell Merging
Resize your columns and rows independently of each other, or synchronize them so they are all sized equally.
Column and Row Sizing
Define the order of columns in the grid, independent of the data source.
Column Ordering
Render any control or set of controls as a part of your grid, including headers, footers, and cells.
Column Template
Choose from the default column type (a TextBox-like appearance), Checkbox (embeds HTML CheckBox controls), DropDownList (selectable list), Button, or Hyperlink (click either navigates or raises a server-side event).
Column Types
