Question

我对WPF Datagrid有一个小问题。我的数据网格项源在名为Case的SQL表中，但是在代码中有几个属性添加到Case。其中之一是ColorForTAT，它包含着色案例的逻辑，但是这个属性对于用户来说不应该是可见的直到现在我设法让它为整行设置背景颜色，但我被要求做的只是着色一列（Name =“TimeTillTatExternal）。我试图谷歌它但找不到任何工作。

        <DataGrid Name="DataGridCase" AutoGenerateColumns="False" IsReadOnly="True" Grid.Row="9" Grid.RowSpan="3"  Grid.ColumnSpan="10" VerticalAlignment="Top" Margin="10,0" SelectionChanged="DataGridCase_SelectionChanged">
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="CaseNumber" Binding="{Binding CaseNumber }" Header="Case Number"/>
            <DataGridTextColumn x:Name="Status" Binding="{Binding FinalStatus }" Header="Tool status"/>
            <DataGridTextColumn x:Name="Title" Binding="{Binding Title }" Header="Title"/>
            <DataGridTextColumn x:Name="Country" Binding="{Binding CountryFromAssignemnt }" Header="Country"/>
            <DataGridTextColumn x:Name="CreatedDate" Binding="{Binding CreatedDate, StringFormat = 'dd/MM/yyyy HH:mm' }" Header="Created date"/>
            <DataGridTextColumn x:Name="TATExternal" Binding="{Binding TATExternal, StringFormat = 'dd/MM/yyyy HH:mm' }" Header="Due date External"/>
            <DataGridTextColumn x:Name="TATInternal" Binding="{Binding TATInternal, StringFormat = 'dd/MM/yyyy HH:mm'  }" Header="Due date Internal"/>
            <DataGridTextColumn x:Name="Assignment" Binding="{Binding Assignment }" Header="Assignment"/>
            <DataGridTextColumn x:Name="TimeTillTatExternal" Binding="{Binding TimeTillTatExternal }" Header="Days left"/>
            <DataGridTextColumn x:Name="Status3" Binding="{Binding LinkedIncident }" Header="LinkedIncident "/>
            <DataGridTextColumn x:Name="Status4" Binding="{Binding ExternalSupport}" Header="ExternalSupport"/>
            <DataGridTextColumn x:Name="Status2" Binding="{Binding SDStatus }" Header="Service Desk Status"/>
        </DataGrid.Columns>
        <DataGrid.ItemContainerStyle>
            <Style TargetType="{x:Type DataGridRow}">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding ColorForTAT }" Value="black">
                        <Setter Property="Background" Value="Gray"/>
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ColorForTAT }" Value="gray">
                        <Setter Property="Background" Value="LightGray"/>
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ColorForTAT }" Value="red">
                        <Setter Property="Background" Value="Red"/>
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ColorForTAT }" Value="yellow">
                        <Setter Property="Background" Value="Yellow"/>
                    </DataTrigger>
                    <DataTrigger Binding="{Binding ColorForTAT }" Value="green">
                        <Setter Property="Background" Value="Green"/>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </DataGrid.ItemContainerStyle>
    </DataGrid>

您需要设置每个列CellStyle并将Background绑定到您可以在Window.Resources声明的静态资源：示例代码如下所示，请根据您的要求更改代码。

<Window x:Class="WpfApplication1.MainWindow" ...>
<Window.Resources>
    <SolidColorBrush x:Key="clBr" Color="White" />
</Window.Resources>

...

列：

  <DataGridTextColumn Header="First Name" 
                                Binding="{Binding Path=FirstName}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Setter Property="Background" 
                            Value="{StaticResource clBr}" />
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>

然后你可以通过代码或xaml操作来操作静态资源。
