Question

我有一个包含Checkbox的DatagridTemplate列，当ItemSource上的属性为“J”时，通过转换器进行检查，当属性为“N”时取消选中。

这样可行，但是现在我希望将属性设置为“J”，如果我选中复选框或“N”则取消选中它。

我的专栏：

<local:JNConverter x:Key="JNConverter" />

<DataGridTemplateColumn Header="">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <ContentControl HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" HorizontalAlignment="Center">
                <CheckBox Name="auto" HorizontalAlignment="center" IsChecked="{Binding Path=Autonummering, Converter={StaticResource JNConverter}, Mode=TwoWay}" />
            </ContentControl>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

我的转换器：

Public Class JNConverter 实现IValueConverter

Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert
    If value IsNot Nothing AndAlso value.ToString.ToLower = "j" Then
        Return True
    Else
        Return False
    End If
End Function

Public Function ConvertBack(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
    If CType(value, Boolean) Then
        Return "J"
    Else
        Return "N"
    End If
End Function

结束班

My Itemsource是一个List（Of Attribuut），Attribuut：

Public Class Attribuut
    Inherits DependencyObject

     Public Shared AutonummeringProperty As DependencyProperty = DependencyProperty.Register("Autonummering", GetType(String), GetType(Attribuut))

    Public Property Autonummering As String

End Class

那么我如何“反向”绑定单击复选框以将自动编号属性更改为“J”或“N”？

将IsChecked-Binding上的UpdateSourceTrigger设置为PropertyChanged，应该这样做。

使用Converter TwoWay绑定的WPF DataGridTemplateColumn复选框元素IsChecked
