我正在关注WPf DataGrid

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

                                               EditingElementStyle="{StaticResource TextBoxCellStyle}"/>
</WPFtoolkit:DataGrid.Columns>
        </WPFtoolkit:DataGrid>

现在我如何在代码隐藏文件后获得各种列的已检查事件。

Answer 1

您可以处理DataGridCheckBoxColumn上绑定的 SourceUpdated 事件。要获得此活动，您还需要设置

NotifyOnSourceUpdated = true

关于该绑定
