WPF类型转换的方式

WPF类型转换的方式

转换的类的编写：
public class BoolToVisibilityConverter2 : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
bool flag = true;
if (value == null)
return Visibility.Collapsed;
if (string.IsNullOrWhiteSpace(value.ToString().Trim()))
{
return Visibility.Collapsed;
}
if (value != null)
flag = bool.Parse(value.ToString().ToLower());
return flag ? Visibility.Visible : Visibility.Collapsed;
}

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)									
        {									
            if (value == null)									
                return true;									
            return ((Visibility)value == Visibility.Visible);									
        }									
    }									

WPF界面的引用：
<Grid.Resources>
<grgcontrol:BoolToVisibilityConverter2 x:Key=“VisibilityConverter2” />
</Grid.Resources>

<StackPanel Orientation="Vertical" HorizontalAlignment="Left" Width="800" Height="200" Margin="775 125 0 0" Visibility="{Binding ElementName=mycomboxTtem0,Path=IsSelected,Converter={StaticResource VisibilityConverter2}}">									
            <TextBlock Style="{DynamicResource Text40RGB46Style}" HorizontalAlignment="Left" Text="{DynamicResource Finacing_bftqje}" />									
            <control:InputControl Margin="-50,-50,215,0" Width="200"									
                              InputNotForeground="White"									
                              Style="{StaticResource InputControlStyle6}" 									
                              TextValue="{Binding saveBuffer, Mode=TwoWay}" 									
                              IsInputFloat="True" 									
                              KeyBoardType="ModeAmount" 									
                              Height="60" Grid.ColumnSpan="3" RegularExpression="^[0-9]+(.[0-9]{2})?$|^[0-9]+(.[0-9]{1})?$" 									
                              RegularTips="{DynamicResource ConfirmPayMentAmount}" MaxDigit="6"  FirstZeroFloat="True" Count="{Binding Count}"									
                              PromptControl="{Binding ElementName=Prompt1}" InitErrorInfo="{DynamicResource ConfirmPayMentInfo}" />									
            <TextBlock Style="{DynamicResource Text40RGB46Style}" HorizontalAlignment="Left" Margin="365 -60 0 0" Text="{DynamicResource MeasureOfCash}" />									
</StackPanel>
