This seems to be a popular confusion. Firstly you cant use
@onchangesince it would internally be used by@bind. You should be able to access the selected value from the setter of yourCustChangedproperty. Based on what you are trying to do with yourCustChanged, you may not even need to manually check when this value is updated. For instance, if your intent is to useCustChangedin your UI directly or indirectly (within Linq or something), the UI would automatically update withCustChangedvalue when youris changed. Hence, for most use cases I don't see the need to check when it was updated.To use
@onchange, you can bind it to a function something like this:public void OnUpdated(ChangeEventArgs e) { var selected = e.Value; }
