如何自动设置表单和datagridview宽度csv

Question

我有一个 Powershell 脚本，我已从 Internet 下载并根据我的目的进行了修改。我的目的是打开 CSV，进行更改，点击保存按钮并 X 输出。

我的问题是我必须手动设置每个 CSV 的宽度（从脚本中）。我可以手动调整表格的增长/缩小，但不能调整 DataGrid

我要

Form 和 DataGrid 根据启动时或手动的列数自动增长或收缩。
当我在列上执行 AutoFit 时，Form 和 DataGrid 自动增长或收缩
如果可以的话我基本上不想要滚动条

我查看了有关 .net 类/方法等的几个文档，并且已经能够推测出很多东西，但这个。我确定我没有问正确的问题。对资源或示例的任何建议将不胜感激。

这是我在打开包含许多列的 csv 时的意思的示例

或几列：

我的代码在这里。

[reflection.assembly]::load("System.Windows.Forms") | Out-Null
[reflection.assembly]::load("System.Drawing") | Out-Null


# This block of code is a file dialog open box
$FileBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{ 
    # This uses Environmental Directory Settings such as Desktop
    # InitialDirectory = [Environment]::GetFolderPath('Desktop')

    # Here you can pick the default directory.  If you comment it out, 
    # then OpenFileDialog seems to go to the last directory you chose a file from
    InitialDirectory = "C:\temp\Ricoh"

    # Pick file extensions to chose from.  The first is default.
    Filter = 'Comma Separated Values (*.csv)|*.csv|All Files (*.*)|*.*|SpreadSheet (*.xlsx)|*.xlsx'
}

# The actual dialog open box
$dialogOpen = $FileBrowser.ShowDialog()

# This returns the full path and filename
$pathFileName = $FileBrowser.FileName
# Write-Host $pathFileName 

# This returns the filename only
$fileName = $FileBrowser.SafeFileName
# Write-Host $fileName 

$OnLoadForm_UpdateGrid= {

    # This returns the filename minus extension.
    $baseName = Get-Item $pathFileName | Select-Object -ExpandProperty BaseName
    # Write-Host $baseName

    $tmp = $FileBrowser.InitialDirectory + '\' + $baseName + '.tmp'
    Write-Host $tmp

    #Make a copy of the file so we can import it and leave the real file free for exporting to
    Copy-Item $pathFileName -Destination $tmp

    # Load the tempfile into memory so we can work
    $tmpFileName = Import-Csv $tmp

    #Remove the tempfile now
    Remove-Item $tmp

    #Select the datasource so we can prep for the dataGridView
    $dataGridView1.DataSource=[System.Collections.ArrayList]$tmpFileName

    $form.refresh()
}


# This button will save the file
$button1_OnClick= {    
    $dataGridView1.Rows |Select -Expand DataBoundItem | Export-Csv $pathFileName -NoType
}

$Form = New-Object system.Windows.Forms.Form
$Form.Text = "Form Text Goes Here"
$Form.TopMost = $true

$form.KeyPreview = $true
$form.StartPosition = "centerscreen"

$dataGridView1 = New-Object System.Windows.Forms.DataGridView -Property @{
}

$sds_width = 900
$sds_height = 450

$form.Size = New-Object System.Drawing.Size($sds_width,$sds_height)

$dataGridView1.Size = New-Object System.Drawing.Size(($sds_width - 25),($sds_height - 100))
$dataGridView1.AutoResizeColumns()
$dataGridView1.AllowUserToOrderColumns = $true
$dataGridView1AllowUserToResizeColumns = $true
$dataGridView1.AutoResizeColumns()

$dataGridView1.Name = $baseName
$dataGridView1.DataMember = ""
$dataGridView1.TabIndex = 0
$System_Drawing_Point = New-Object System.Drawing.Point
$System_Drawing_Point.X = 5
$System_Drawing_Point.Y = 5

$dataGridView1.Location = $System_Drawing_Point
$form.Controls.Add($dataGridView1)
$form.add_Load($OnLoadForm_UpdateGrid)

$button = New-Object Windows.Forms.Button
$button.text = "Save"
$button.Location = New-Object Drawing.Point(5,($dataGridView1.height + 25))
$button.Size = New-Object Drawing.Point(125, 25)

$button.Anchor = [System.Windows.Forms.AnchorStyles]::Bottom -bor [System.Windows.Forms.AnchorStyles]::Right

$button.TabIndex ="1"
$button.add_Click($button1_OnClick)
$form.controls.add($button)

$form.ShowDialog()
$form.Dispose()

我们可以让您的 UI 自动调整大小，但我们需要删除硬编码的 size 值并将其转换为 .MinimumSize。您可能还想添加 .MaximumSize 属性，否则有人可能会打开一个巨大的 .csv 文件并得到一个非常难看的文件 UI。

我们还想将 .AutoScale 和 .AutoSize 属性设置为 true，以便整体更改看起来像。

$form.MinimumSize= New-Object System.Drawing.Size($sds_width,$sds_height)
$form.AutoScale = $true
$form.AutoSize = $true

我们还需要在 DataGridView 上设置相同的属性。

$dataGridView1.MinimumSize = New-Object System.Drawing.Size(($sds_width - 25),($sds_height - 100))
$dataGridView1.AutoScale...

我也运行出错了，因为我没有 C:\temp\Ricoh 路径，所以你可能想在 line 38 上放置一些错误处理，比如

if (Test-Path C:\temp\Ricoh){
   Write-Host "Found C:\temp\Ricoh path"
}
else{
   New-item "C:\temp\Ricoh" -ItemType Directory 
}

现在，我并没有说它看起来会很漂亮，尤其是如果用户像我一样有奇怪的缩放比例。

您可能想要做的一件事是设置 Column's Header Height property, like in this article.
