Data binding-Features of WPF

• WPF has a built-in set of data services to enable application developers to bind and manipulate data within applications.
• There exists support for three types of data binding:
• one time: where the client ignores updates on the server.
• one way: where the client has read-only access to data.
• two way: where client can read from and write data to the server.
• A set of built-in controls is provided as part of WPF, containing items such as button, menu, grids and list box.
• A powerful concept in the WPF is the logical separation of a control from its appearance.
• A control's template can be overridden to completely change its visual appearance.
  and a control can contain any other control or layout, allowing for unprecedented control over composition.
• Features retained mode graphics, so that applications do not have to be bothered with repainting the display.
