我想获取所选行,但是selecteditems只有一行。我想得到所有检查项目。我想我需要在选中复选框时添加事件处理程序,然后将它们全部收集起来。我该如何以最好的方式做到这一点?

您是否使用数据绑定来填充DataGrid?如果是这样,将列的已检查值绑定到后备对象中的bool可能是“最佳”(如:最佳实践)方式。以下是一些示例代码:
<Window x:Class="CheckGridSample.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:tk="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit"
Title="Window1" Height="300" Width="300">
<StackPanel>
<tk:DataGrid ItemsSource="{Binding}" AutoGenerateColumns="False">
<tk:DataGrid.Columns>
<tk:DataGridTextColumn Header="Name" Binding="{Binding Name}" />
<tk:DataGridCheckBoxColumn Header="Selected" Binding="{Binding IsChecked}" />
</tk:DataGrid.Columns>
</tk:DataGrid>
<Button Content="Which Items Are Checked?" Click="Button_Click" />
</StackPanel>
</Window>
using System;
using System.Linq;
using System.Text;
using System.Windows;
namespace CheckGridSample
{
public partial class Window1
{
public Window1()
{
InitializeComponent();
DataContext = new[]
{
new MyModel {Name = "Able"},
new MyModel {Name = "Baker", IsChecked = true},
new MyModel {Name = "Charlie"}
};
}
private void Button_Click(object sender, RoutedEventArgs e)
{
var builder = new StringBuilder();
foreach (var item in ((MyModel[]) DataContext).Where(m => m.IsChecked))
builder.Append(Environment.NewLine + item.Name);
MessageBox.Show("Checked:" + builder);
}
}
public class MyModel
{
public string Name { get; set; }
public bool IsChecked { get; set; }
}
}
