From an internal DL ... I thought this would be handy --- must admit is nicer than some hacks I have done in the past to accomplish same thing..

You’ll need to know the dependency object and dependency property where the binding was defined, which may not qualify as elegant.  Then you can use this line:

 

BindingOperations.GetBindingExpressionBase(dependencyObject, dependencyProperty).UpdateTarget();

I have a control that has a list of stuff, and once I make a change to some unrelated thing I really need to force the binding to re-run… is there any elegant way to make this happen? Something like “InvalidateMeasure” but for binding… ?
