WPF ComboBox / ListBox with Enum-based MultiSelect with flags

Question

So I can push the borders a bit ...

Basically, I have the following enumeration declared in C # code:

[Flags]
public enum FlaggedEnum : int
{
    Option1 = 1,
    Option2 = 2,
    Option3 = 4,
    Option4 = 8,
    ...
    Option16 = 32768,
    None = 0
}

This enumeration is a member of the object that I have successfully bound to the DataGrid. Successfully this means that I successfully linked all the other fields. :)

What I want to achieve here is a control that marks all the relevant parameters above that behave and act like a ComboBox / ListBox. Thus, you click on the field and a drop-down menu appears with the ability to "check" which parameters are needed.

The control will also need to read from the enumeration and write the enumeration.

WPF, , ComboBox ... !

/// <summary>

/// TODO: make this more generic and add it to the converter dictionary if possible
/// </summary>
public class TestActionFlagValueConverter : IValueConverter {

    public TestActionFlagValueConverter() {

    }

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {
        TestErrors mask = (TestErrors)parameter;
        this.target = (TestErrors)value;
        return ((mask & this.target) != 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) {
        this.target ^= (TestErrors)parameter;
        return this.target;
    }
}

xaml :

<StackPanel.Resources>
    <local:TestActionFlagValueConverter x:Key="TestActionFlagValueConverter"/>
</StackPanel.Resources>

<CheckBox IsChecked="{Binding Errors, Converter={StaticResource TestActionFlagValueConverter}, ConverterParameter={x:Static local:TestErrors.PowerFailure}...
<CheckBox IsChecked="{Binding Errors, Converter={StaticResource TestActionFlagValueConverter}, ConverterParameter={x:Static local:TestErrors.OpenCondition}...
