There is a checkbox that is already binded to boolean field "IsOutsourcing"
<CheckBox x:Name="chkIsOutsourcing" IsChecked="{Binding IsOutsourcing, Mode=TwoWay}" />
And I need to check it when checked another checkbox.
<CheckBox x:Name="chkIsOption1" IsChecked="{Binding IsOption1, Mode=TwoWay}" />
How ot can be done with XAML?
Can we use here multiple elements to bind?
IsChecked="{Binding IsOutsourcing chkIsOption1, Mode=TwoWay}"
Thanks!
This can be done using MultiBinding with MultiValueConverter.
<CheckBox x:Name="chkIsOutsourcing">
<CheckBox.IsChecked>
<MultiBinding Converter="{StaticResource BooleanConverter}">
<Binding Path="IsOutSourcing" />
<Binding Path="IsChecked"
ElementName="chkIsOption1" />
</MultiBinding>
</CheckBox.IsChecked>
</CheckBox>
The Converter,
public class BooleanConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
bool value1 = (bool)values[0];
bool value2 = (bool)values[1];
return value1 || value2;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
