WPF DataGrid 改变单元格字体颜色或单元格背景颜色（二）

与上一篇 WPF DataGrid 改变单元格字体颜色或单元格背景颜色（一） 里的后台实现方法一样，改变前台XAML代码：

前台XAML代码：

<Window x:Class="WpfDataGridCellColors.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:loca="clr-namespace:WpfDataGridCellColors"
        Title="MainWindow" Height="261" Width="649">

    <Window.Resources>
        <loca:ColorConverter x:Key="MyColorConvert"/>
    </Window.Resources>

    <Grid>
        <DataGrid CanUserDeleteRows="False" CanUserAddRows="False" 
                  AutoGenerateColumns="False" IsReadOnly="True"                 
                  Name="dataGrid"  Background="White" 
                  GridLinesVisibility="All" Margin="5" 
                  ScrollViewer.VerticalScrollBarVisibility="Visible"
                  ScrollViewer.HorizontalScrollBarVisibility="Visible"
                      HeadersVisibility="Column"  AlternationCount="2">

            <DataGrid.Columns>

                <DataGridTextColumn Binding="{Binding Title}" Header="项目" Width="150"/>

                <DataGridTemplateColumn Width="150" >
                    <DataGridTemplateColumn.HeaderTemplate>
                        <DataTemplate>

                            <TextBlock Text="A" />

                        </DataTemplate>
                    </DataGridTemplateColumn.HeaderTemplate>
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>

                            <TextBlock Text="{Binding IA}" VerticalAlignment="Center" HorizontalAlignment="Center"
                                               Foreground="{Binding AFColor}"/>

                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>


                <DataGridTemplateColumn Width="150" >
                    <DataGridTemplateColumn.HeaderTemplate>
                        <DataTemplate>

                            <TextBlock Text="B" />

                        </DataTemplate>
                    </DataGridTemplateColumn.HeaderTemplate>
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>

                            <TextBlock Text="{Binding IB}" VerticalAlignment="Center" HorizontalAlignment="Center"
                                               Foreground="{Binding BFColor}"/>

                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>

                <DataGridTemplateColumn Width="150" >
                    <DataGridTemplateColumn.HeaderTemplate>
                        <DataTemplate>

                            <TextBlock Text="C" />

                        </DataTemplate>
                    </DataGridTemplateColumn.HeaderTemplate>
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>

                            <TextBlock Text="{Binding IC}" VerticalAlignment="Center" HorizontalAlignment="Center"
                                               Foreground="{Binding CFColor}"/>

                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>

            </DataGrid.Columns>

        </DataGrid>
    </Grid>
</Window>

这里列单元格模版里的Foreground直接绑定后台的Color属性，要将其变为什么颜色，可在后台代码里进行控制，然后直接绑定到前台代码中。

如下面后台代码中所示的：

ContrastList.Add(new Contrasts()
                {
                    Title = "减数",
                    IA = 110,
                    AFColor = Brushes.Black,
                    IB = 220,
                    BFColor = Brushes.Red,
                    IC = 330,
                    CFColor = Brushes.Green
                });

        }
