Abstract

The state of one or more server-side control objects is managed using a transportable state structure that is communicated between a web server and a client. The transportable state structure may include state information, hierarchical information, and an integrity code. The state information is related to properties of the server-side control objects. The hierarchical information is used by the server to locate an appropriate server-side control object in the hierarchy into which associated state information is to be loaded. The integrity code allows the server to determine whether the transportable state structure was corrupted during the round-trip between the server and the client. Prior to a response to the client, the state information of one or more server-side control objects is recorded into the transportable state structure for transmission to the client in the response. The transportable state structure is then returned to the server and loaded into the server-side control objects to restore the hierarchy to its previous state.

Claims

1. A method for managing a state of a server-side control object corresponding to a client-side user interface element incorporated in a web page displayed on a client, the method comprising:

creating the server-side control object to process the client-side user interface element;

receiving from the client a transportable state structure including state information indicating a state value for at least the one server-side control object, and

loading the state value from the state information into a property of the server-side control object, if the state value is associated with the server-side control object.

2. A computer program storage medium readable by a computer system and encoding a computer program for executing a computer process that manages a state of a server-side control object corresponding to a client-side user interface element incorporated in a web page displayed on a client, the computer process comprising:

creating the server-side control object to process the client-side user interface element;

generating a state value from the service-side control object responsive to data received from the client;

loading the state value into a transportable state structure ; and

sending the transportable state structure to the client.

3. The computer program storage medium of claim 2 wherein the computer process further comprises:

terminating the server-side control object;

receiving the state value from the client in a transportable state structure; and
