I think using MVVM is very well adapted to manage any situation : In the case of an internationalised application(in my case), external libraries have no access to Resources where are translations, so I cannot set appropriated message.I'm posting this because I expect a lot of people will be wondering how to emulate this. In this article, I'll demonstrate my version of the ErrorProvider, written specifically for the Windows Presentation Foundation. The Validating event handler on the textbox gets called first, and in that handler, when no text has been set in the textbox, I set the Cancel property of the CancelEventArgs argument to true, cutting the event chain so it never reaches the Cancel button click event. The ErrorProvider will then automagically display any errors on your objects, with no need to write validation code on the UI. Most of the information about the controls is still applicable to previous versions of PrimalForms. This works only if the rule is always the same for a same class (in my case I have some quantities, that sometimes can be negative, sometimes not). But it cant reach the click event handler of the Cancel button. The Spotlight on Controls series focuses on a single WinForms control in PrimalForms 2011, details the important Properties, Methods, and Events of the control and demonstrates how to utilize the control.Using responseTemplate makes the response slower when displaying the error.

One possible solution I have read about is to have a SetError method defined in the View and implemented by the Form which takes the control name and error message as arguments and sets the error for the specified control e.g. The ErrorProvider has two properties related to blinking. ![]() One issue I can't seem to find a clean solution to is how to wire up a Presenter with a windows forms ErrorProvider control.
