Question

How can you remove a wpf element by some kind of name? So sth like :

// Bar is some kind of usercontrol
Bar b = new Bar();
b.Tag = "someId";
theCanvas.Children.Add(b);

// Later to be removed without having the reference 
theCanvas.Children.RemoveElementWithTag("someId")

Except ofcourse, RemoveElementWithTag isn’t an existing method…

Answer 1

Could just use some LINQ:

var child = (from c in theCanvas.Children
             where "someId".Equals(c.Tag)
             select c).First();
theCanvas.Children.Remove(child);

That said, I highly suspect there’s a cleaner, better performing way to achieve whatever it is you’re trying to achieve.
