binding

问题 Is it possible to bind the same property of the control more than once?

Trying @Arhiman answer without much success: <Popup.IsOpen> <MultiBinding Converter="{local:MultiBindingConverter}">

问题 I have a labels that need values retreieved from a Database.

问题 I have a infinite scroll script which works for my tumblr. It's loading images as I scroll down the page. However I'm looking to have the images fade in rather than suddenly appear. I've found this awesome plugin called waypoints which does this sort of thing. And it works, but only on the first loaded images. After that, it's not recognising the newly loaded images. I know that "live" only works on certain jQuery functions. And bind might be better as you can use custom functions. But then i
