Remarks

When you specify data to persist at the client, this property provides greater flexibility compared with the ViewStateContent property.

When the user-defined view state is implemented, it is up to the developer to set the view state, and to utilize the view state when a postback occurs.

The Save and Load methods of the ChartSerializer object can optionally be used to set the view state, as well as to load the view state when a postback occurs. See the sample code below for an example of this.

For simplicity, when you specify the chart state to be saved, use the ViewStateContent property, which can be set to data, visual appearance properties or both.

To enable state management, set the EnableViewState property to true.
