Your question is just a one liner, we would require more details to help you. why you are doing this ? Did you search for the windows forms .net documentation ?

You have to change your form code behind to do what you are asking. This is not a PS specific issue.
So, you are bringing in a dataset as array to populate the datagrid, so, you need to write more code to act on a selected line, thus, you need to ask your code behind to do the remove / re-run effort.

So, use the normal remove from the in memory array dataset, and refresh and re-run from buttons you provide or event triggers you set.

Very rough not fully vetted example - just showing the selection code behind:

$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.CurrentRow.Index
    write-host $selectedRow
})
[void]$form.ShowDialog()
