我试图根据DataGrid列中的值更改边框（我指的是组件）BrushColor（见屏幕）。我想我只是错过了一些愚蠢的事情... How it should see for example when Type of Alarm is High编辑：在App.xaml中标记我想更改的BorderBrush我已经尝试过：

<DataGrid 
                    RowStyle="{DynamicResource DataGridRowStyle2}"
                    Name="AlertTable"
                    Grid.Row="5"
                    BorderBrush="{Binding TypeOfAlert , Converter={StaticResource CellConverter}}" // Got 
                    IsReadOnly="True"
                    BorderThickness="0"
                    ScrollViewer.HorizontalScrollBarVisibility="Hidden"
                    ScrollViewer.VerticalScrollBarVisibility="Viditelný"
                    >
<DataGrid.DataContext>
                        <local1:CellConverter/>
                    </DataGrid.DataContext>
<!-- ---- -!>
<DataGrid />

第二次尝试，但它只适用于文本块！：

<DataGridTextColumn
                            Header="Type of Alert "
                            Width="*"
                             Binding="{Binding TypeOfAlert}"
                            >
                            <DataGridTextColumn.ElementStyle>
                                <Style 
                                    TargetType="{x:Type TextBlock}"
                                    >
                                    <Setter
                                        Property="Background"
                                        Value="{Binding TypeOfAlert , Converter={StaticResource CellConverter}}"
                                        >
                                        
                                    </Setter>
                                    
                                </Style>
                            </DataGridTextColumn.ElementStyle>
                        </DataGridTextColumn>

在应用程序xaml中

<Style x:Key="DataGridRowStyle2" TargetType="{x:Type DataGridRow}">
                <Setter Property="Background" Value="Transparent"/>
