Log doesn't uses "String.Format"

[negue]

This is what I get from AdRotatorControl.Log => "Control {0} - Trying provider AdDuplex", where is the {0} Parameter? :)

:D.

It is using string.format.

Basically the number relates to the instance of AdRotator that is being logged. It isn't a parameter, it's just a wrapped number.

Might change the {} to [ ] instead so it's a bit clearer.

If you use more than one AdRotator control (and you can also specify the instance number on initialisation) then you can get specific reporting on each control through the one Log event.

Oh, I see xD.

So I could only set the number if I would create the AdRotatorControl in the codebehind but not in the XAML-Created one?

If you don't set one, AdRotator will set one for you.
However your point about assigning a code in XAML is an interesting one, will have to investigate how to do that, probably through another property.
But yes, currently assigning the ID is only available in code behind as that is where the request came from
