I directly bind the field, but it is not working. I can't change the visibility, It stays as visible as default, even though I used the same exact code for binding. 

I don't know why but I can't upload the project, let me illustrate my problem with static resource, 

My visibility property is something like this 

        public bool IsVisible
        {
            get
            {
                foreach (var person in People)
                {
                    if (person.Age < 18)
                    {
                      return true;
                    }

                }

               return false;
            }
        }

The visibility of the column is not bound to some property that I change, but the condition of some properties. 

So in your example I bind it to the people list, if there is someone with the age lower than 18, the age column should visible if not invisible. 

But since adding static resource create a new instance of the view model, this solution is not works as expected.

Is there any other way?  

thank you, it works  as expected
