Jose,
You could try adding the View to the DE with NoDataOnLoad option selected. Then in the GotFocus (or there appropriate point) of the class set the necessary parameters and do a Requery.

>Look I want to open a View with parameter from the class and in the name of this stand of class, it will be its parameter reason why I prefer to avoid to have to handle it in the DE of the form, is possible to open a Vista by code from the class?
