我有以下DataGrid代码
<UserControl x:Class="abc.WPFApp.UCGrid"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:WPFtoolkit="http://schemas.microsoft.com/wpf/2008/toolkit"
xmlns:local="clr-namespace:abc.WPFApp">
<UserControl.Resources>
<!--Restrict editing based on IsVariable-->
<Style x:Key="CheckBoxCellStyle" TargetType="{x:Type CheckBox}">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=IsVariable}" Value="true">
<Setter Property="IsEnabled" Value="false"/>
</DataTrigger>
</Style.Triggers>
<Setter Property="HorizontalAlignment" Value="Center"/>
</Style>
</UserControl.Resources>
<Grid>
<WPFtoolkit:DataGrid x:Name="UCdataGridView" ItemsSource="{Binding}"

<WPFtoolkit:DataGridTextColumn x:Name="dgXPath" Binding="{Binding Path=XPath}" Header="XPath" Width="500"

此用户控件Grid包括三个相互排斥的列.
我想通过在XAML本身中创建触发器来实现这一点,我们该怎么做?
解决方法:
您可以使用具有复选框样式的单选按钮来实现互斥行为.如果在绑定单选按钮时遇到任何问题:radiobutton-binding
<RadioButton IsChecked="{Binding VMProperty}" GroupName="IsSelectedGroup">
<RadioButton.Style>
<Style TargetType="{x:Type RadioButton}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="RadioButton">
<CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay, RelativeSource={RelativeSource AncestorType=RadioButton}}" Content="{TemplateBinding Content}" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</RadioButton.Style>
</RadioButton>
但是,我同意贾斯特.如果将每一行都绑定到一个ViewModel,则放置此逻辑限制的位置就是ViewModel.
