How to find whether a property on a XAML object is bindable or not in WPF/Silverlight-Collection of common programming errors

I use intellisense for it.
Say I want to know wheter or not Background for TreeViewItem is bindable (is dependency property), I type TreeViewItem.Background in the code behind file and if a BackgroundProperty pops up then I know its bindable (it’ll also say DependencyProperty in the ToolTip just to be sure).

If I wanted to check IsLoaded instead there wouldn’t be an IsLoadedProperty since IsLoaded isn’t a dependency property.

But I agree, there has to be a better way
