                            <DataGridTextColumn x:Name="br_valor" Width="90" Header="VALOR" Binding ="{Binding Path=CNS_VALOR_TOTAL, StringFormat={}{0:#.##}}" HeaderStyle="{StaticResource ColumnHeaderGripperStyle}" />
                            <DataGridTextColumn x:Name="br_chave_de_acesso" Width="350" Header="CHAVE DE ACESSO" Binding ="{Binding Path=CNS_VALOR_TOTAL, StringFormat={}{0:#.##}}" HeaderStyle="{StaticResource ColumnHeaderGripperStyle}" />
                        </DataGrid.Columns>                    
                    </DataGrid>

有没有办法将这些事件放在行中？

我正在尝试使用此代码

<Style TargetType="{x:Type DataGridRow}">
    <MultiTrigger>
        <MultiTrigger.Conditions>
            <Condition Property="local:HideShow.Somefunction" Value="False"/>
            <Condition Property="IsFocused" Value="True"/>
        </MultiTrigger.Conditions>
    </MultiTrigger>
</Style>

但它也不起作用

我终于意识到该怎么做了 Jus需要使用EventSetter而不是触发器

如下面的代码

<EventSetter Event="MouseEnter" Handler="Row_MouseEnter"/>

C＃WPF DataGrid行MouseOver事件
