我怎么能传递2个值给我的ValueConverters类
本文关键字:我的 ValueConverters 2个 怎么能 | 更新日期: 2023-09-27 17:49:35
我已经在我的Xaml上得到了这个,我正在传递分配给改变网格颜色的值。但我想同时检查输入的变量值,这样我就可以根据它来改变。我怎么能传递2个值,这样我就可以在我的转换器类上有条件。
<DataGridTextColumn Binding="{Binding Allocated}" Header="Allocated" >
<DataGridTextColumn.ElementStyle>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="Background" Value="{Binding Allocated, Converter={StaticResource converter}}"/>
</Style>
</DataGridTextColumn.ElementStyle> </DataGridTextColumn>
my Converter class:
IValueConverter对象。转换(对象值,类型targetType,对象参数,System.Globalization.CultureInfo文化){
string input = value.ToString();
switch (input)
{
case "99":
return Brushes.Green;
case "96":
return Brushes.Green;
case "91":
default:
return DependencyProperty.UnsetValue;
}
}

提前感谢!
使用MultiBinding
:
<DataGridTextColumn.ElementStyle>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="Background">
<Setter.Value>
<MultiBinding Converter="{StaticResource converter}">
<Binding Path="Allocated" />
<Binding Path="Entered" />
</MultiBinding>
</Setter.Value>
</Setter>
</Style>
</DataGridTextColumn.ElementStyle>
,让你的convet实现IMultiValueConverter
:
public class MyConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType,
object parameter, CultureInfo culture)
{...
