我有以下的DataGrid代码:
<UserControl x:Class="abc.WPFApp.UCGrid"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
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}"
CellStyle="{StaticResource defaultCellStyle}"
RowStyle="{StaticResource defaultRowStyle}"
ColumnHeaderStyle="{StaticResource defaultDataGridColumnHeader}"
SelectionUnit="FullRow"
IsSynchronizedWithCurrentItem="True"
RowBackground="White"
AlternatingRowBackground="AliceBlue"
AutoGenerateColumns="False" SelectionMode="Extended" RowHeaderWidth="20"
CanUserAddRows="True" CanUserDeleteRows="True" CanUserReorderColumns="False"
CanUserResizeColumns="True" AllowDrop="True" KeyUp="UCGridKeyUp" >
<WPFtoolkit:DataGrid.Columns>
<WPFtoolkit:DataGridCheckBoxColumn x:Name="dgChkRepeatingData" Binding="{Binding Path=MasterDataFlag}" MaxWidth="135" MinWidth="80"
Header="Repeating data" Visibility="Collapsed" IsReadOnly="{Binding (IsVariable)}"
EditingElementStyle="{StaticResource CheckBoxCellStyle}"
>
</WPFtoolkit:DataGridCheckBoxColumn>
<WPFtoolkit:DataGridCheckBoxColumn MaxWidth="100" Header="Max Element" x:Name="dgChkMaxElement"
Binding="{Binding Path=MaxElement}" MinWidth="70" Visibility="Collapsed"
EditingElementStyle="{StaticResource CheckBoxCellStyle}">
</WPFtoolkit:DataGridCheckBoxColumn>
<WPFtoolkit:DataGridCheckBoxColumn MaxWidth="100" Header="In For Loop" x:Name="dgChkInForLoop"
Binding="{Binding Path=InForLoop}" MinWidth="70" Visibility="Collapsed"
EditingElementStyle="{StaticResource CheckBoxCellStyle}">
</WPFtoolkit:DataGridCheckBoxColumn>
<WPFtoolkit:DataGridTextColumn x:Name="dgXPath" Binding="{Binding Path=XPath}" Header="XPath" Width="500"
Visibility="Collapsed" IsReadOnly="{Binding Path=IsVariable}"
EditingElementStyle="{StaticResource TextBoxCellStyle}"/>
</WPFtoolkit:DataGrid.Columns>
</WPFtoolkit:DataGrid>
这个用户控件 Grid 由三列组成,这些列应该是互斥的。我希望通过在 XAML 中创建触发器来实现这一点,我们该怎么做?
