How-to Drag and Drop from a DataGridView to a ListBox

I would like to know how I can drag some data from a datagridview to a listbox. I see alot of examples about dragging files from the explorer to a listbox in a powershell script, but I cannot find an example about drag and drop between two powershell objects.

I have seen some VB examples, but I cannot translate them to powershell (I have never programmed in VB).

The code below is an example, of what I want.

Regard,

Marco

#region DefineForm
    #Define Form1
    $form1 = New-Object System.Windows.Forms.Form
    $form1.Text = "form1"
    $form1.Name = "form1"
    $form1.DataBindings.DefaultDataSourceUpdateMode = 0
    $form1.Location = New-Object System.Drawing.Point(1,1)
    $form1.WindowState = "Normal"
    $form1.StartPosition = "CenterScreen"
    $Form1.AutoSize = $True
    $Form1.AutoSizeMode = "GrowAndShrink"
