Remarks
An expression editor is a Visual Basic control used to edit expressions inside Visual Studio. This control provides a full-fledged IDE editing experience, including IntelliSense, colorization, ParamInfo, error squiggles, among other features. An expression editor is created when an ExpressionTextBox instance gains focus and is destroyed on losing focus of a valid expression, or on reloading of the designer. Expression editors are not available for use in rehosted applications. If you are using an ExpressionTextBox control in a custom activity designer, it is not necessary to create and destroy expression editors using this interface. The ExpressionTextBox class manages this for you.
