同时在两个wpf datagrid中选择一行

Question

对于我正在从事的项目，我需要能够例如在grid1中选择第一行，并自动在grid2中也选择第一行，以便在两个网格中同时选择一行。

已经尝试了什么

• 使用堆叠

我创建了一种方法来设置GIDS中的所选项目

        private void SyncDataGridItemSelection(int number)
        {
        //sync pricegrid with printertick grid
        if (number == 1)
        {
            int printertickselection = PrinterTicksGrid.SelectedIndex;
            //detachs change event
            PrinterPriceGrid.SelectionChanged -= (PrinterPriceGrid_SelectionChanged);
            //change printerpricegrid selection
            PrinterPriceGrid.SelectedIndex = printertickselection;
            //attach change event
            PrinterPriceGrid.SelectionChanged += (PrinterPriceGrid_SelectionChanged);
        }
        //sync printertick grid with price grid
       else if (number == 2)
        {
            int printerpriceselection = PrinterPriceGrid.SelectedIndex;
            //detachs change event
            PrinterTicksGrid.SelectionChanged -= (PrinterTicksGrid_SelectionChanged);
            //change PrinterTicksgrid selection
            PrinterTicksGrid.SelectedIndex = printerpriceselection;
            //attach change event
            PrinterTicksGrid.SelectionChanged += (PrinterTicksGrid_SelectionChanged);
        }
    }

我还查看了MSDN的文档，其中涉及重点，但没有成功。

GUI已经存在，因此无法重写

这甚至有可能做到吗？

Answer 1

问题尚不清楚。 如果始终选择相同的行，则可以将所有数据放在一个数据网格中，除非需要特定的布局。 但是，让我尝试按原样解决您的问题。 您可以将两种选择类型合并为一个类。 这两个Datagrids可以彼此连接，而无需使用经典事件。 解决方案如下所示：

XAML

    <Window x:Class="WpfApplication2.MainWindow"
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    Title="MainWindow" Height="229.584" Width="270.818">
        <Grid>
            <DataGrid AutoGenerateColumns="False" Name="DG1" HorizontalAlignment="Left" Height="190" Margin="10,0,0,0" VerticalAlignment="Top" Width="116" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}" >
                <DataGrid.Columns>
                    <DataGridTextColumn Header="Data A" Binding="{Binding AData.data}"/>
                </DataGrid.Columns>
            </DataGrid>
            <DataGrid AutoGenerateColumns="False" Name="DG2" HorizontalAlignment="Left" Height="190" Margin="131,0,0,0" VerticalAlignment="Top" Width="116" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}" >
                <DataGrid.Columns>
                    <DataGridTextColumn Header="Data B" Binding="{Binding BData.data}"/>
                </DataGrid.Columns>
            </DataGrid>
        </Grid>
    </Window>

    using System.Collections.Generic;

    using System.Windows.Documents;

    namespace WpfApplication2 {
        public class A {
            public int data { get; private set; }
            public A(int x) { data = x; }
        }

        public class B {
            public string data { get; private set; }
            public B(string x) { data = x; }
        }

        public partial class MainWindow : Window {

            public MainWindow() {
                InitializeComponent();

                List<A> lIntegers = new List<A>() { new A(1), new A(2), new A(3), new A(4) };
                List<B> lStrings = new List<B>() { new B("a"), new B("b"), new B("c"), new B("d") };
                List<C> lParent = new List<C>();

                for (int i = 0; i < 4; i++) {
                    C c = new C();
                    lParent.Add(c);
                    c.AData = lIntegers[i];
                    c.BData = lStrings[i];
                }

                DG1.DataContext = lParent;
                DG2.DataContext = lParent;
            }
        }
    }
