Comentários

When the expression is a property expression, the EditPropertyExpression method is simpler to use than the EditExpression method. The EditPropertyExpression method determines the return type of the expression from the data type of the property and assigns the expression to the property for you. However, you can also use the EditExpression method whenever you want to let the user create or modify an expression.
