我想找到一种方法将 DataGrid 行的背景颜色绑定到绑定对象的属性。
这是我的 XAML：
<sdk:DataGrid ItemsSource="{Binding MyItems}" />
我正在将 MVVM Light Toolkit 与 Silverlight 4 结合使用。
您可以通过更改行模板来做到这一点：
<sdk:DataGrid ItemsSource="{Binding MyItems}">
<sdk:DataGrid.RowStyle>
<Style TargetType="sdk:DataGridRow">
<Setter Property="Template">
...
<Rectangle x:Name="BackgroundRectangle" Fill="{Binding ColorPropertyOfItem}" />
...
</Setter>
</Style>
</sdk:DataGrid.RowStyle>
</sdk:DataGrid>
或者，您可以将每列标记为 TemplateColumn 并在每列中显式设置背景颜色：
<sdk:DataGridTemplateColumn Header="ColumnName" SortMemberPath="ColumnProperty">
<sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding ColumnProperty}" Background="{Binding ColorPropertyOfItem}" />
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
这是一个完整的模板DataGridRow class:
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:DataGridRow"

并且不要忘记改变Binding ColorPropertyOfItem该类型的不动产Brush在你的模型中。
