The ExpressionEditorAttribute class specifies the design-time expression editor for the expressions that are handled by an ExpressionBuilder class.

When editing a control property, you can set the property value to an expression by using an editor for the expression.

When developing an expression builder, you can mark the builder with the ExpressionEditorAttribute attribute to set the editor type value.
