我从列表中生成数据网格内容。我需要能够将数据网格中选定行的“名称”单元格的值传递给子窗口的 texblock。通过单击上下文菜单项启动子窗口。该场景是用户在选定行“名称”单元格上单击鼠标右键，然后选择启动子窗口的上下文菜单项。ChildWindow 使用数据网格中该单元格的文本块文本值启动。任何想法都受到高度赞赏！先感谢您！

带有上下文菜单的数据网格：

<sdk:DataGrid x:Name="dgPack" ItemsSource="{Binding Source={StaticResource PackagesCollectionViewSource}}">
<InputToolkit:ContextMenuService.ContextMenu>
        <InputToolkit:ContextMenu x:Name="cmPackages_DataGrid" DataContext="{Binding Source={StaticResource GlobalLabelsDataSource}}">
        <InputToolkit:MenuItem x:Name="item1" Header="item1"/>
        <InputToolkit:MenuItem x:Name="GetChildWindow" Header="GetChildWindow" Click="GetChildWindow_Click"/>
        </InputToolkit:ContextMenu>
    </InputToolkit:ContextMenuService.ContextMenu>
<sdk:DataGrid.Columns>
    <sdk:DataGridTextColumn x:Name="DataGrid_Name"  Binding="{Binding Name}" Header="Name" />
    <sdk:DataGridTextColumn x:Name="DataGrid_Version" Binding="{Binding Version}" Header="Version"  />
    <sdk:DataGridTextColumn x:Name="DataGrid_Size"  Binding="{Binding Size}" Header="Size" />
</sdk:DataGrid.Columns>

启动子窗口的代码中的方法：

private void GetChildWindow_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        var selectedItem = PackVM.SelectedPack;

        if (selectedItem != null)
        {
            var bpw = new GetChildWindow1_ChildWindow(selectedItem.Id);
            bpw.Show();
        }
    }

列表：

public List<Pack> GetCollection()
    {
        return new List<Pack>() 
        { 
            new Pack() { Name="item1", Size=10, Version="1"},
            new Pack() { Name="item2", Size=12, Version="5", },
        };
    }

最后是子窗口：

<Grid x:Name="LayoutRoot">
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions
    <Button x:Name="OKButton" Content="OK" Click="OKButton_Click" Width="75" Height="23" Margin="0,0,79,0" HorizontalAlignment="Right" Grid.Row="1" />
    <Button x:Name="CancelButton" Content="Cancel" Click="CancelButton_Click" Width="75" Height="23" HorizontalAlignment="Right" Grid.Row="1" />
    <TextBlock x:Name="Message" HorizontalAlignment="Left" TextWrapping="Wrap" Text="" VerticalAlignment="Top"/>
</Grid>

I don't know if I've understand correctly your question but I think you can solve it this way:

-Declare a public method in the child window code behind like "SetText(string text)"

-In this method, just set Message.Text = text

public void SetText(string text)
{
    this.Message.Text = text;
}

-Now, call this method before calling show method from parent window:

bpw.SetText(selectedItem.PropertyWithTheText);

This should work.

Anyway, you should take a look to MVVM to solve this kind of stuff ;-)
