I'm in a little bit of a pickel, here it is:

I have a MainWindow.xaml using a userControl. This latter needs a path to function properly and has it passed through a public string property.

The MainWindow is coupled with a viewmodel in which I do the work needed to create the path needed above.

Is there a clean way to set the userControl's path property from the MainWindow.xaml, such as for instance a binding to one of its viewmodel's properties? Something like 

<uc:MyUserControl x:Name="controlsName" 
    PathPropertyNeeded="{Binding ViewModelsProperty}" />

你需要一个依赖属性：

是的，您只需要确保它PathPropertyNeeded是一个依赖属性。
