WPF: How to hide GridViewColumn using XAML?

Question

I have the following object in App.xaml

Answer 1

In a small utility I wrote, I have a list view where the user can hide/show some columns. There is no Visibility property on the columns, so I decided to set the hidden columns width to zero. Not ideal, as the user can still resize them and make them visible again.

Anyway, to do this, I used:

IsThreadIdShown is bound to a check box on the toolbar. And the multi-value converter is:

public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) {
    if (values.Length != 2) {
        return null;
    }

    object o0 = values[0];
    object o1 = values[1];

    if (! (o1 is bool)) {
        return o0;
    }
    bool toBeDisplayed = (bool) o1;
    if (! toBeDisplayed) {
        return 0.0;
    }

    if (! (o0 is double)) {
        return 0;
    }

    return (double) o0;
}

public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture) {

    return new object[] { (double)value, Binding.DoNothing };
}
