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
});

后台代码：

using System.Linq;
using System.Text;

using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;

}

public MainWindow()

ContrastList = new List<Contrasts>();

ContrastList.Add(new Contrasts()

IA = 110,
AFColor = Brushes.Black,
IB = 220,
BFColor = Brushes.Red,
IC = 330,

});

dataGrid.ItemsSource = ContrastList;
}
}
