Is possible to have a new state of InvalidValueBehavior that rappresent nothing (exemple None)?I need a state that does not do anything at the control, I manually check the control through the property IsValidValue.
Thanks for reply.
Hello Matteo,
Have you tried the InvalidValueBehavior property to RetainValue or perform validation in the EditModeEnded event. Does this work in your scenario?
Alex.
No, I want that, if the value is wrong the user can continue to fill the form (with the wrong value) and at the end, when the user confirms, I show a message with the errors.Is possible to do it?
Ok, but I have to make a custom validation instead I want exploit the property ValueConstraint of the xamEditors.Is right?
Thanks for reply
Well, how about when the user Submits the form ( I guess it is a button click event ) ?
No, doesn't work. I have a form to fill not a grid.
Hello,
Well, you cannot add new InvalidValueBehavior. This is not supported and solution for this would require some manual code. Have you tried handling the RecordUpdated event ( or RecordAdding event if you add new Record), performing the validation for every cell and display error message. Tell me if that works in your scenario?
