推荐答案

是的，您只需要获取数据绑定所使用的样本数据实例。

Yes, you just need to get ahold of the instance of sample data being used by databinding.

 

默认情况下，示例数据将datacontext设置为在app.xaml（如果您选择项目范围）或控件的资源（如果您选择此文档）中创建的对象。以下示例适用于项目范围：

By default, sample data sets the datacontext to an object created either in app.xaml (if you picked project scope) or in your control's resources (if you picked this document). The example below is for the project scope:

 

private void AddRow(object sender, System.Windows.RoutedEventArgs e)
		{
			var sd = Application.Current.Resources["SampleDataSource"] as Expression.Blend.SampleData.SampleDataSource.SampleDataSource;
			sd.Collection.Add(new Item() { Property1 = "New Item", Property2 = true });
		}
