Vista - Designer Considerations

Is it possible to have a constructor or a method that can only be used
by the designer? The designer requires a default (empty) constructor
but I do not want to allow an empty constructor into my API. If I
could have an empty one that is some how marked (attribute maybe) to
only be allowable in the designer that would rock.

I have no luck searching for something like this.

Thanks

Hi,

talking about Blend, or the WPF designer in Visual Studio (Cider)? And
for which type of object? A Custom Control?

If you want to allow a method to be used by the designer, but not by
anyone else, you have two options:

1) Enclose the method in a
#if DEBUG
#endif
block. This will exclude the code from the release version of your
library/application. The code will only be available in the debug version.

2) Inside the method, add the following code:

public Music()
{
if (!DesignerProperties.GetIsInDesignMode(new DependencyObject()))
{
throw new ApplicationException("This method may only be used by the
designer");
}
}

I have a custom window object and the WPF Designer in Visual Studio
insists on an empty constructor for it.
I will try your code snippet for it.
