The situation:
I used VS2005 to create a win form. I placed same text boxes, added a bindingsource and bound it to a business object. Then i added a binding tothe text property of the text box. So far so good.

The business object implementsa property related to the text box and an event called <property name>Chanced to support updating thetext box.

Question:
I'd like to check the input of thetext box during setting the value in the business object. Is there any event i can implement to get the same error-support as datagrits getfrom "data binding"?

My english isn't the best but i hope you understand it. Sorry.
