Question

I want to control the visibility of an image (inside a dynamically bind longlistselector control), depending on a binding value (say if somevalue>0 then make that image visible otherwise invisible).But there is no such event like itemdatabound in the longlistselector to accomplish this task, I am new to windows phone development, and really don’t have an idea how to do this.Please help me guys.

Thanks,

Use a ValueConverter

public class BoolToVisiblityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return (bool)value
            ? Visibility.Collapsed
            : Visibility.Visible;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
