An instance of the System.Web.UI.Design.ExpressionsCollectionEditor class is a System.Drawing.Design.UITypeEditor object that can be used at design time to select and edit a collection of expression bindings, and assign the expressions to a control property.
A designer host, such as vsprvslong, uses the System.Web.Compilation.ExpressionBuilder and System.Web.UI.Design.ExpressionEditor class implementations with the System.Web.UI.Design.ExpressionsCollectionEditor and System.Web.UI.Design.ExpressionsCollectionConverter classes to set the expression bindings for control properties at design time, and the System.Web.UI.Design.ControlPersister class to persist the expressions for run time. Expression strings reference a localizable resource, an application setting, a connection string, or a custom expression type. The expression string is bound to the control property at design time, and then used at run time to determine the value for the property.
