Description

Error messages with default and custom validators will shown up only if i blur out on my form control. When i type on a minLength textfield a smaller amount of text, the error message will only shown if i switch to another form element, or click out of my form. This state is not helpful for my formular. I need to display the error messages (if a error exist) immediately (onchange instead of blur out). Is there any method to do this?
