Remarks

An Action Container View Item is used to display a particular Action Container in a UI. The ActionContainerViewItem class is an abstract class from which all the Action Container View Items derive. The following table lists XAF‘s built-in Action Container View Items.

WebActionContainerViewItem	The Action Container View Item used in the XAF ASP.NET Web Forms applications.

The ActionContainerViewItem exposes the ActionContainerViewItem.BeginUpdate and ActionContainerViewItem.EndUpdate methods designed to implement batch modifications with Action Container View Items. This allows you to prevent excessive updates when changing multiple settings at once. For this purpose, enclose the code that changes multiple properties within calls to these methods.
