【问题描述】:
我有一个 IValueConverter 类,我希望将它的值除以我在 rntime 期间选择的数量!但是,不知道有没有可能!!
IvalueConverter
class salesUIbtnWidth : IValueConverter
{
public double myValue { get; set; }
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return (double)value / myValue;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
尝试实现类
<Button Text="Click me" HorizontalOptions="Center" VerticalOptions="Center"
CornerRadius="15" WidthRequest="{Binding Source={x:Reference
frame}, Path=Width,Converter={StaticResource salesUIbtnWidth}}">
</Button>//how to bind also the MyValue
我只想知道如何在运行时从 xamarin 的 (IvalueConverter) 中设置 myValue!
