PowerShell WPF中DataGrid第一列与网格间多余间隙消除咨询

你看到的第一列左侧间隙是WPF DataGrid默认启用的行标题列，这个列默认会保留占位空间（即使不显示行号），导致出现多余空隙。要消除它，只需修改DataGrid的HeadersVisibility属性：

解决步骤 #

在你的DataGrid配置代码中添加以下一行：

$dataGridView1.HeadersVisibility = [Windows.Controls.DataGridHeadersVisibility]::Column

这个属性的可选值说明：

• All：默认值，同时显示列标题和行标题
• Column：仅显示列标题，隐藏行标题列（消除左侧间隙）
• Row：仅显示行标题
• None：列标题和行标题都隐藏

修改后的完整代码 #

$dataGridView1 = New-Object Windows.controls.DataGrid 
$dataGridView1.Name = 'ListBox1'
$dataGridView1.AutoGenerateColumns = $false
$dataGridView1.HorizontalAlignment = "Stretch"
$dataGridView1.VerticalAlignment = "Stretch"
$dataGridView1.ColumnWidth = "*"
$dataGridView1.Margin = New-Object Windows.Thickness(20, 200, 20, 20)

$dataGridView1.SelectionMode = [Windows.Controls.DataGridSelectionMode]::Single
$dataGridView1.CanUserResizeRows = $false
$dataGridView1.CanUserResizeColumns = $false
# 添加这一行消除左侧间隙
$dataGridView1.HeadersVisibility = [Windows.Controls.DataGridHeadersVisibility]::Column

$printerNameColumn = New-Object Windows.Controls.DataGridTextColumn
$printerNameColumn.Header = "Printer Name"
$printerNameColumn.Binding = New-Object Windows.data.Binding("ShareName")
$dataGridView1.Columns.Add($printerNameColumn)

$printerLocationColumn = New-Object Windows.controls.DataGridTextColumn 
$printerLocationColumn.Header = "Location"
$printerLocationColumn.Binding = New-Object Windows.data.Binding("Location")
$dataGridView1.Columns.Add($printerLocationColumn)
