DataGrid MVVM 根据特定内容改变某些行的颜色

1.绑定的数据，特定的字段，绑定到DataGrid

2.在xaml文件中，修改DataGrid的颜色变化条件

<DataGrid.RowStyle>
                <Style TargetType="{x:Type DataGridRow}" BasedOn="{StaticResource dataGridRowStyle}">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding IsExecCal}" Value="True">
                            <Setter Property="Background" Value="Green"></Setter>
                        </DataTrigger>

                        <MultiDataTrigger>
                            <MultiDataTrigger.Conditions>
                                <Condition Binding="{Binding IsExecCal }" Value="False" />
                                <Condition Binding="{Binding  SampleNoColor}" Value="True" />
                            </MultiDataTrigger.Conditions>
                            <Setter Property="Background" Value="White"></Setter>                            
                        </MultiDataTrigger>

                        <MultiDataTrigger>
                            <MultiDataTrigger.Conditions>
                                <Condition Binding="{Binding IsExecCal }" Value="False" />
                                <Condition Binding="{Binding  SampleNoColor}" Value="False" />
                            </MultiDataTrigger.Conditions>
                            <Setter Property="Background" Value="#E2E9E1"></Setter>
                        </MultiDataTrigger>


                    </Style.Triggers>
                </Style>
