如何在WPF Datagrid中更改单元格背景色

问题描述:

当我选择一个单元格并在UI中单击红色按钮或蓝色按钮时,我想在WPF Datagrid应用程序中更改单元格背景颜色。

I want to change the cell background color in my WPF Datagrid application when I select a cell and click on "Red Button" or "Blue Button" in UI.

我是WPF Datagrid架构的初学者,非常感谢有人可以帮助我。 (我在应用程序中使用MVVM)

I'm a beginner to this WPF Datagrid architecture and really appreciate if someone can help me with this. (I'm using MVVM for my application)

尝试以下代码:

<DataGrid Name="SampleDataGrid" 
          AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Status" Binding="{Binding State}" Width="100">
            <DataGridTextColumn.ElementStyle>
                <Style TargetType="{x:Type TextBlock}">
                    <Setter Property="Background" Value="OrangeRed"/>
                    <Style.Triggers>
                        <Trigger Property="Text" Value="Completed">
                            <Setter Property="Background" Value="GreenYellow"/>
                        </Trigger>
                    </Style.Triggers>
                </Style>
            </DataGridTextColumn.ElementStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>
