Powershell GUI Datagridview items to a combobox Question

Hello,

I am working on a powershell GUI project and have a datagridview with data i pulled from SQL that part works.

What i want to do it get a rows of a column to show in a combobox for selection.

Later i want to click a button to query the other columns of the row the username is on to populate text boxes.

Here is my code so far minus the SQL part that works.

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

$Form                            = New-Object system.Windows.Forms.Form
$Form.ClientSize                 = '800,500'
$Form.text                       = "Form"
$Form.TopMost                    = $false
$Form.FormBorderStyle = 'Fixed3D'
$Form.MaximizeBox = $false

#$gps | foreach {$dataGridView.Rows.Add($result)}
#$list = New-Object System.collections.ArrayList
#$list.AddRange($gps)

$dataGridView = New-Object System.Windows.Forms.DataGridView -Property @{
    Size=New-Object System.Drawing.Size(800,400)
    ColumnHeadersVisible = $true
    DataSource = $table
}


$dataGridView.location          = New-Object System.Drawing.Point(4,2)
$dataGridView.SelectionMode = 'FullRowSelect'
$dataGridView.MultiSelect = $true

$ComboBox1                      = New-Object system.Windows.Forms.ComboBox
$comboBox1.DropDownStyle =      [System.Windows.Forms.ComboBoxStyle]::DropDownList;
$ComboBox1.text                  = ""
$comboBox1.Sorted = $true
$ComboBox1.width                 = 190
$ComboBox1.height                = 20
$ComboBox1.location              = New-Object System.Drawing.Point(171,427)
$ComboBox1.Font                  = 'Microsoft Sans Serif,10'


$connection.Close()
$Form.controls.AddRange(@($DataGridView,$ComboBox1))
$form.ShowDialog()

Example of the SQL datagridview output:
