Bind visibility property to a variable

Question

I have a Border with Label inside a Window,

Answer 1

You don't need to make any converter.

Add a binding to a Visibility property for the border:

And then create the property Visibility in a viewmodel like this:

private Visibility visibility;
public Visibility Visibility
    {
        get
        {
            return visibility;
        }
        set
        {
            visibility = value;

            OnPropertyChanged("Visibility");
        }
    }

So, now you can set Visible or Hidden to your Visibility property as follow:

Visibility = Visibility.Visible;
// or
Visibility = Visibility.Hidden;

But remember, Visibility enum is located in System.Windows namespace, so your viewmodel has to contain using System.Windows;.
