关于WPF中Binding绑定的数据获取不到

之前的工程师通过DataReportTestResultConverter和DataReportMaintenanceConverter来添加循环添加数据

<UserControl.Resources>
        <local:DataReportTestResultConverter x:Key="DataReportTestResultConverter"/>
        <local:DataReportMaintenanceConverter x:Key="DataReportMaintenanceConverter"/>
    </UserControl.Resources>

数据绑定是这样的

 <DataGridTextColumn x:Name="columnHeader5" CanUserSort="False" CanUserReorder="False" Header="实验结论" ElementStyle="{StaticResource DataGridTextCenter}" Width="*">
                        
                        <DataGridTextColumn.Binding>
                            <MultiBinding Converter="{StaticResource ResourceKey=DataReportTestResultConverter}">
                                <Binding Path="StartVoltage"/>
                                <Binding Path="EndVoltage"/>
                                <Binding Path="dicLanguages"/>
                            </MultiBinding>
                        </DataGridTextColumn.Binding>
                    </DataGridTextColumn>

                    <DataGridTextColumn x:Name="columnHeader6" CanUserSort="False" CanUserReorder="False" Header="维护方案" ElementStyle="{StaticResource DataGridTextCenter}" Width="*">
                        <DataGridTextColumn.Binding>
                            <MultiBinding Converter="{StaticResource ResourceKey=DataReportMaintenanceConverter}">
                                <Binding Path="StartVoltage"/>
                                <Binding Path="EndVoltage"/>
                            </MultiBinding>
                        </DataGridTextColumn.Binding>
                    </DataGridTextColumn>

就是这两列下的数据我在Datatable中怎么找都找不到，我要通过什么方法获取到呢

这个已经解决了，还是通过后台代码往表格里添加数据，然后同时触发器在前台获得数据更改样式

要看代码里怎么设置DataContex的
