WPF Radiobutton (two) (binding to boolean value)

Question

I have a property of type boolean presented with checkbox.

I want to change that to two radiobuttons that bind on the same property presenting the value true/false.<

Answer 1

When using MVVMLight and DataContext is set in XAML as:

DataContext="{Binding <Your ViewModel property name>, Source={StaticResource Locator}}" 

BoolInverterConverter causes Stack Overflow second time the window gets opened.

The work around is to remove DataContext from XAML and do it in code in window constructor after InitializeComponent():

DataContext = ServiceLocator.Current.GetInstance<Your View Model class>();

After some testing it was not enough - Stack Overflow error could pop up randomly when clicking on radio button. The solution which worked for me - instead of the converter use another property for other radio button in a group:

public bool Is9to1 { get; set; }
public bool Is1to9 { get { return !Is9to1; } set { Is9to1 = !value; } } 

in XAML:

   <RadioButton GroupName="Is9to1" IsChecked="{Binding Is1to9}"/>
   <RadioButton GroupName="Is9to1" IsChecked="{Binding Is9to1}"/>
