Powershell: Selecting DataGridView Row

问题

So far I have this code.

$form = New-Object System.Windows.Forms.Form
$form.Size = New-Object System.Drawing.Size(900,600)
$dataGridView = New-Object System.Windows.Forms.DataGridView
$dataGridView.Size=New-Object System.Drawing.Size(800,400)
$go = New-Object System.Windows.Forms.Button
$go.Location = New-Object System.Drawing.Size(300,450)
$go.Size = New-Object System.Drawing.Size(75,23)
$go.text = "Select"
$form.Controls.Add($go)
$form.Controls.Add($dataGridView)


$dataGridView.ColumnCount = 4
$dataGridView.ColumnHeadersVisible = $true
$dataGridView.Columns[0].Name = "Name"
$dataGridView.Columns[1].Name = "ID"
$dataGridView.Columns[2].Name = "Description"
$dataGridView.Columns[3].Name = "Memory"

$dataGridView.Columns[0].width = 240

get-process | foreach {
    $dataGridView.Rows.Add($_.Name,$_.ID,$_.Description,$_.WorkingSet) | out-null
}

$go.Add_Click({
    $selectedRow = $dataGridView.CurrentRowIndex
write-host $selectedRow
})

[void]$form.ShowDialog()

It simply gets the Process Name, ID, etc. properties and puts them into pre-defined headers in a DataGridView.

My problem is that I want to see the row I've clicked on via $selectedRow = $dataGridView.CurrentRowIndex and output it to the console. Instead, when the 'Select' button is pushed, a blank string is output to the terminal.

回答1:

You can also get the row index with:

$dataGridView.CurrentCell.RowIndex

$dataGridView.SelectedRows[0].Index

You may also want to set the grid MultiSelect property to $false. Currently it allows multiple rows selection. Another thing to consider is setting the SelectionMode property to 'FullRowSelect'. When the grid is populated the first column is selected, not the whole row.

Change

$selectedRow = $dataGridView.CurrentRowIndex

$selectedRow = $dataGridView.CurrentRow.Index
