Set ContextMenu items from a string list - powershell

Question

Basically I'm trying to create a ContextMenu that shows a list of mounted network drive, so the user can click on one and access it.
The problem is : the list is not fix, but depend on a string list extracted from a DataGrid.
In my mind, I could just create the menu items by looping on that string list.
Here is the code sample :
$Main_Tool_Icon = New-Object System.Windows.Forms
[...]
# Add menu entries
$contextmenu = New-Object System.Windows.Forms.ContextMenu
$Main_Tool_Icon.ContextMenu = $contextmenu
foreach ($nameTag in $dataGrid[$DATAGRID_COLUMN_NAME]){
$menuEntry = New-Object System.Windows.Forms.MenuItem
$menuEntry.Text = $nameTag
$Main_Tool_Icon.ContextMenu.MenuItems.AddRange($menuEntry)
}
# Add separator
$Main_Tool_Icon.ContextMenu.MenuItems.Add('-')
# Last one to show main form
$displayMainform = New-Object System.Windows.Forms.MenuItem
$displayMainform.Text = "Edit"
$Main_Tool_Icon.ContextMenu.MenuItems.Add($displayMainform)
It appears that's wrong and only shows the separator and last "Edit" line.
Is there a way to populate a contextual menu with a list ?
Or I should look for a better way to do the job ?

You're right about AddRange(), it's just a mistake.
I can't show everything since it's quite big. I'll try to synthesize an answer properly.
The data grid is created/populated by my script and is just a table of strings from a csv file.
$DATAGRID_COLUMN_NAME = 'NAME' it's one of constants defined for my datagrid headers.
Here is the setup
# set datagrid
$dataGrid = New-Object System.Windows.Forms.DataGridView
[...]
$dataGrid.Columns.Add($DATAGRID_COLUMN_NAME,'Name')
$dataGrid.Columns[0].DataPropertyName = $dataGrid.Columns[0].Name
Then some databinding
# initiate the data table
$table = New-Object System.Data.DataTable
[...]loop on csv file[...]
# bind data table to data grid
$dataGrid.DataSource = $table
EDIT #SantiagoSquarzon
You were right for pointing out $dataGrid[$DATAGRID_COLUMN_NAME]. The syntax was bad and returned something null. Instead, I looped over the $dataGrid.Rows like so:
foreach ($row in $dataGrid.Rows){
$nameTag = $row.Cells[$DATAGRID_COLUMN_NAME].Value
if ($nameTag -ne $null){
$menuEntry = New-Object System.Windows.Forms.MenuItem
$menuEntry.Text = $nameTag
$Main_Tool_Icon.ContextMenu.MenuItems.AddRange($menuEntry)
}
}
Now I just have to figure out how to invoke there click event.
