How to Implement a BoolToVisibilityConverter

Question

In my app I would like to toggle the visibility of an item in a StackPanel. My Stackpanel contains an Image and a TextBlock. How would I properly use a BoolToVisibilityConverter to toggle the visibility of the TextBlock, and save this setting for the users benefit? Currently what I have is as follows, although I am getting a few errors. Important note, I need to use an ApplicationBar menu item as the click event that drives the toggling of the TextBox visibility. EDIT Error no longer occurring although the visibility of the TextBlock is not changing. XAML ``` xmlns:common="clr-namespace:TestApp.Common"

Accepted Answer

Try this:

```
public class BooleanToVisibilityConverter : IValueConverter
{
    private object GetVisibility(object value)
    {
        if (!(value is bool))
            return Visibility.Collapsed;
        bool objValue = (bool)value;
        if (objValue)
        {
            return Visibility.Visible;
        }
        return Visibility.Collapsed;
    }
    public object Convert(object value, Type targetType, object parameter, string language)
    {
        return GetVisibility(value);
    }
    public object ConvertBack(object value, Type targetType, object parameter, string language)
    {
        throw new NotImplementedException();
    }

}
```
