我将行与类绑定(bind)。
我想在每个绑定(bind)行上根据单元格值更改单元格背景色。

如何根据值更改单元格的背景色。
我在dtstandardview_LoadingRow事件上执行了操作，但是没有工作。
最佳答案
在Triggers上的DataGridCell集合Style中添加以下内容
<DataGrid ItemsSource="{Binding Items}">
<DataGrid.CellStyle>
<Style TargetType="{x:Type DataGridCell}">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=Value}" Value="true">
<Setter Property="Background" Value="Red" />
</DataTrigger>
</Style.Triggers>
</Style>
</DataGrid.CellStyle>
</DataGrid>
这将是您的 View 模型和实体类
public class MyViewModel
{
public MainWindow()
{
DataContext = this;
Items =
new ObservableCollection<MyEntity>
{
new MyEntity(true),
new MyEntity(false),
new MyEntity(true)
};
}
public ObservableCollection<MyEntity> Items { get; set; }
}
public class MyEntity
{
public MyEntity(bool value)
{
Value = value;
}
public bool Value { get; set; }
}
关于wpf - 想要更改WPF DataGrid中的单元格背景颜色，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/14847463/
