WPF 精修篇 多值转换器

效果

 

贴码

首先需要一个多值转换器

    class TextMulti:IMultiValueConverter
    {
        #region IMultiValueConverter 成员

        public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return values[0] + " " + values[1] + " " + values[2];
        }

        public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
        {
            return value.ToString().Split(' ');
        }

        #endregion
    }

 

<Window.Resources>
        <local:TextMulti x:Key="TextMulti"/>
    </Window.Resources>
    <Grid>
        <TextBox x:Name="tex1" HorizontalAlignment="Left" Height="23" Margin="48,105,0,0" TextWrapping="Wrap"  VerticalAlignment="Top" Width="120"/>
        <TextBox x:Name="tex2" HorizontalAlignment="Left" Height="23" Margin="195,105,0,0" TextWrapping="Wrap"  VerticalAlignment="Top" Width="120"/>
        <TextBox x:Name="tex3" HorizontalAlignment="Left" Height="23" Margin="351,105,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="120"/>
        <TextBox x:Name="tex4" HorizontalAlignment="Left" Height="23" Margin="29,188,0,0" TextWrapping="Wrap"  VerticalAlignment="Top" Width="466">
            <TextBox.Text>
                <MultiBinding Converter="{StaticResource TextMulti}">
                    <Binding ElementName="tex1" Path="Text" Mode="TwoWay"/>
                    <Binding ElementName="tex2" Path="Text" Mode="TwoWay"/>
                    <Binding ElementName="tex3" Path="Text" Mode="TwoWay"/>
                </MultiBinding>
            </TextBox.Text>
        </TextBox>

    </Grid>
