WebPartManager Web Server Control Declarative Syntax
Serves as the central class of the Web Parts control set, managing all the Web Parts controls, functionality, and events that occur on a Web page.

Remarks
The WebPartManager control acts as the hub or control center of a Web Parts application. There must be one—and only one—instance of the WebPartManager control on each page that uses Web Parts controls and it must be placed before any zone controls are placed. As with most aspects of Web Parts applications, the WebPartManager control works only with authenticated users. Further, its functionality works almost entirely with server controls that reside within Web Parts zones that inherit from the WebZone class. Server controls that reside on a page outside of these zones can have very little Web Parts functionality or interaction with the WebPartManager control.
For more information on the WebPartManager and Web Parts controls, see ASP.NET Web Parts Controls.
Example
The following code example demonstrates how to use the WebPartManager control declaratively in a Web Parts scenario using the Calendar control. The Web page allows a user to enter edit mode to edit certain aspects of the Calendar control. The Toggle Scope button switches the page to user or shared personalization scope. The Edit Mode and Browse Mode buttons each switch the page into the appropriate display mode. Notice that in the <script> tag section of the file, two of the methods that handle events use the Personalization property to access useful members of the underlying object. Specifically, these methods use the ToggleScope method and the Scope property on the object that is accessed through the Personalization property.
For the code example to run, you also must enable one or more users to personalize pages in shared scope. To do this, add an entry to the Web.config file, in the webParts Element (ASP.NET Settings Schema).
