how to bind a boolean to combobox in wpf

Well I was wondering how to bind a boolean property to a combobox.Combobox will be a yes/no combobox.


You could use a ValueConverter to convert the boolean value to a ComboBox index and back. Like this:

public class BoolToIndexConverter : IValueConverter
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
            return ((bool)value == true) ? 0 : 1;   

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
            return ((int)value == 0) ? true : false;

Assuming Yes is on index 0 and No on index 1. Then you'd have to use that converter in binding to the SelectedIndex property. For this, you declare your converter in your resources section:

    <local:BoolToIndexConverter x:Key="boolToIndexConverter" />

Then you use it in your binding:

<ComboBox SelectedIndex="{Binding YourBooleanProperty, Converter={StaticResource boolToIndexConverter}}"/>
