Visual Basic (Usage)

Property Value

Type: System.Web.UI..::.ExpressionBindingCollection

An ExpressionBindingCollection that contains the expressions strings set for properties in the current control.

Remarks

The design host, such as Visual Studio 2005, uses the ExpressionBuilder class to get the ExpressionEditor class to get the ExpressionEditorSheet to set expressions for control properties at design time. Expression strings reference a localizable resource, an application setting, a connection string, or a custom expression type.

The Expressions collection contains an ExpressionBinding element for each control property that has an associated expression string. Each ExpressionPrefix property for each element indicates the associated expression builder implementation. The expression string is parsed and evaluated by its associated ExpressionBuilder to determine the control property value at run time.
