Remarks
You can use the EditExpression method whenever you want to let the user create or modify an expression. However, to modify a property expression, the EditPropertyExpression method might be more useful. 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.
