currently I'm trying to implement the RadExpressionEditor for creating custom Grid view groups. Everything is working fine besides the ExpressionChanged event of the RadExpressionEditor. The event is not called every time the expression changed. If I enter the following expression:
"Sample: " + GetFormattedField("1282", "N2")
Expression changed is called.
if I remove the last bracket ExpressionChanged gets fired and the expression is invalid (this behaviour is correct). If I add the bracket again, ExpressionChanged IS NOT fired. This behaviour occurse in different scenarios. This makes it difficult to trust the system, because we have a lot of invalid expressions, even a valid expression is entered.
