Thank you for writing.
Let me start with a quick overview of how the expression editor works so we can work from there. When the user inputs an expression string into the editor its parser is started and the string is evaluated for validity. If the expression is valid the Expression
property of the editor is set to the valid expression, if not the property is set to null
. This is when the ExpressionChanged
event is fired, if the value of the Expression
property changes the event gets fired. I tested the expression editor and the behavior was exactly as described above. This is why, I would kindly ask you to send me a sample where the behavior you have described can be reproduced. This will allow me to investigate the exact case you have and to give you the most accurate response possible.
Looking forward to your reply.
