Programmatically assigning a color to a row in DataGrid
提问by Abdul Khaliq
I need to assign a color to the row I add at runtime to the DataTable. How can this be done?
我需要为我在运行时添加到 DataTable 的行分配颜色。如何才能做到这一点？

You can handle the DataGrid's LoadingRow event to detect when a row is being added. In the event handler you can get a reference to the DataRow that was added to the DataTable that is acting as your ItemsSource. Then you can update the DataGridRow's color however you like.
您可以处理 DataGrid 的 LoadingRow 事件以检测何时添加行。在事件处理程序中，您可以获得对添加到充当您的 ItemsSource 的 DataTable 的 DataRow 的引用。然后您可以随心所欲地更新 DataGridRow 的颜色。
void dataGrid_LoadingRow(object sender, Microsoft.Windows.Controls.DataGridRowEventArgs e)
{
// Get the DataRow corresponding to the DataGridRow that is loading.
DataRowView item = e.Row.Item as DataRowView;
if (item != null)
{
DataRow row = item.Row;
// Access cell values values if needed...
// var colValue = row["ColumnName1]";
// var colValue2 = row["ColumName2]";
// Set the background color of the DataGrid row based on whatever data you like from
// the row.
e.Row.Background = new SolidColorBrush(Colors.BlanchedAlmond);
}
}
To sign up for the event in XAML:
要在 XAML 中注册活动：
<toolkit:DataGrid x:Name="dataGrid"
...
LoadingRow="dataGrid_LoadingRow">
Or in C#:
或者在 C# 中：
this.dataGrid.LoadingRow += new EventHandler<Microsoft.Windows.Controls.DataGridRowEventArgs>(dataGrid_LoadingRow);

U can try this
你可以试试这个
In the XAML
在 XAML 中
<Window.Resources>
<Style TargetType="{x:Type DataGridRow}">
<Style.Setters>
<Setter Property="Background" Value="{Binding Path=StatusColor}"></Setter>
</Style.Setters>
</Style>
</Window.Resources>
In the datagrid
在数据网格中
<DataGrid AutoGenerateColumns="False" CanUserAddRows="False" Name="dtgTestColor" ItemsSource="{Binding}" >
<DataGrid.Columns>
<DataGridTextColumn Header="Valor" Binding="{Binding Path=Valor}"/>
</DataGrid.Columns>
</DataGrid>
In the code i have a class with
在代码中，我有一个类
public class ColorRenglon
{
public string Valor { get; set; }
public string StatusColor { get; set; }
}
When set the DataContext
设置 DataContext 时
dtgTestColor.DataContext = ColorRenglon;
dtgTestColor.Items.Refresh();
If u not set the color of the row the default value is Grey
如果你没有设置行的颜色，默认值是灰色
u can try this sample with this sample
你可以用这个样本试试这个样本
List<ColorRenglon> test = new List<ColorRenglon>();
ColorRenglon cambiandoColor = new ColorRenglon();
cambiandoColor.Valor = "Aqui va un color";
cambiandoColor.StatusColor = "Red";
test.Add(cambiandoColor);
cambiandoColor = new ColorRenglon();
cambiandoColor.Valor = "Aqui va otro color";
cambiandoColor.StatusColor = "PaleGreen";
test.Add(cambiandoColor);

IMPORTANT: be sure to always assign defaults for rows that aren't being colored by a condition - or any other style.
重要提示：确保始终为未按条件或任何其他样式着色的行分配默认值。

PS. I am in Silverlight and haven't confirmed this behavior in WPF
