wpf - PowerShell XAML WPF 窗口获取值

Question

很好很容易解释，但很难找到答案。

在下面的代码中，打开了一个漂亮的框，当您选择一行时，会出现一个包含更多数据的子行。我想要做的是访问子行标题。

[void][System.Reflection.Assembly]::LoadWithPartialName( 'presentationframework' )

[xml]$XAML = @'


    <Window

        WindowStyle="ToolWindow">
        <Grid>

            <Grid Background="#FF0A2F64">
                <DataGrid Name="Datagrid" AutoGenerateColumns="True" HorizontalAlignment="Left" VerticalAlignment="Top"

                                        <RowDefinition Height="Auto" />
                                        <RowDefinition Height="Auto" />
                                        <RowDefinition Height="Auto" />

                                    <TextBlock Text="Disabled Machines: " FontWeight="Bold" Grid.Row="2" />
                                    <TextBlock Text="{Binding SamAccountDisabled}" Grid.Column="1" Grid.Row="2" />

                                    <TextBlock Text="Servers: " FontWeight="Bold" Grid.Row="3" />
                                    <TextBlock Text="{Binding Servers}" Grid.Column="1" Grid.Row="3" />
                                </Grid>
                            </DockPanel>

                    </DataGrid.RowDetailsTemplate>

                </DataGrid>


            </Grid>

</Grid>
</Window>

'@

#Read XAML
$READER  = ( New-Object System.Xml.XmlNodeReader $XAML ) 
Try {
    $FORM    = [Windows.Markup.XamlReader]::Load( $READER ) 
}
Catch {
    Write-Host "Unable to load Windows.Markup.XamlReader."
    Sleep 4 
}

$XAML.SelectNodes( "//*[@Name]" ) | %{ Set-Variable -Name ( $_.Name ) -Value 
$FORM.FindName( $_.Name ) }


 $datagrid.AddChild( [pscustomobject]@{ 
            Domain       = "happytimes.local"
            LiveMachines = 6
            DR           = 1
            Servers      = 2
            SamAccountDisabled = 3
        } )

$form.ShowDialog()

因此，如果我这样做$datagrid.Columns.header，我可以访问“域”、“Total Live PCs”和“DR”——我在 foreach 循环中使用它们。这是我试图访问的“域”、“禁用的机器”和“服务器”。$datagrid.items给我所有的数字，但我无法进一步分解。

我错过了什么吗？任何想法我如何获得变量？

谢谢
