I'm using ValidationRules to do the data check on UI. When I set the ValidationStep to UpdatedValue, it works weird. When the input is incorrect, the control shows a red border as normally. However, after I changed the value correctly, the red border won't go off. Why is this happening?
As far as I know, in UpdatedValue mode, the validation happens after the source value been updated. That is to say when I changed the input into correct one, the source object's property value changed as well. So in this case, the value in UI and in source are both correct. Why is the red border still there?
By the way, things work fine in RawProposedValue mode.
Thanks a lot.
