Hello there,

i have a little problem to generate a Context Menu in Powershell.
I have built a form with different window forms on it (e.g. a normal textbox) via Primal Forms CE
Now i want to generate a context menu with different features in it and link it to the textbox:
If the textbox is right clicked a menu opens with different entries in it.
Now i have some problems in realising it:

1. How can i  build a new context menu
2. How can i add new items to the menu
3. How can i link it with a special form (e.g. textbox)
4. How can i use handler for the different items in the context menu

Would be nice if somebody can help me here.

Thanks in advance

Regards,
Tom

All types deriving from System.Windows.Forms.Control have a ContextMenu property. Setting it up should be pretty straight forward:

$contextMenu = New-Object System.Windows.Forms.ContextMenu # Create context menu
$menuItem1 = New-Object System.Windows.Forms.MenuItem -ArgumentList "Hello"
$menuItem2 = New-Object System.Windows.Forms.MenuItem -ArgumentList "Hello Again"

$contextMenu.MenuItems.Add($menuItem1) # Add option to context menu
$contextMenu.MenuItems.Add($menuItem2)

$textBox.ContextMenu = $contextMenu # Assuming you've assigned your TextBox instance to $textBox

As for the event handler, I'm not entirely sure about that, but looking at this blog: http://blogs.msdn.com/powershell/archive/2008/05/24/wpf-powershell-part-3-handling-events.aspx

... it looks like it's done this way:

$menuItem1.Add_Click({ [System.Windows.Forms.MessageBox]::Show("Hello Clicked!") })
$menuItem2.Add_Click({ [System.Windows.Forms.MessageBox]::Show("Hello Again Clicked!") })

Sorry I re-read your question and realised you were using PrimalForms, not WinForms. I think its a slightly different syntax for event handling, plus a ContextMenuStrip may be better if you're not bothered about backwards compatability:

$contextMenuStrip = New-Object System.Windows.Forms.ContextMenuStrip # Create context menu

$menuItem1 = New-Object System.Windows.Forms.ToolStripMenuItem -ArgumentList "Hello"
$menuItem1_OnClick({ [System.Windows.Forms.MessageBox]::Show("Hello Clicked!") })
$menuItem2 = New-Object System.Windows.Forms.ToolStripMenuItem -ArgumentList "Hello Again"
$menuItem2_OnClick({ [System.Windows.Forms.MessageBox]::Show("Hello Again Clicked!") })

$contextMenuStrip.Items.Add($menuItem1) # Add option to context menu
$contextMenuStrip.Items.Add($menuItem2)

$textBox.ContextMenuStrip = $contextMenuStrip # Assuming you've assigned your TextBox instance to $textBox

Hello GWHowarth,

thanks so far, the creation of context menu is working, also the "add option".
The event handling is not working.
I changed the "on_click" event to the following because i got some errors in ps:

$menuItem2_OnClick=
{
[System.Windows.Forms.MessageBox]::Show("Hello Again Clicked!")
}
Now the errors are gone and the programm is starting, but nothing happens when i choose one of the items.
Do you perhaps have a idea again?

Thank you for your help

Try this instead:

$contextMenuStrip = New-Object System.Windows.Forms.ContextMenuStrip # Create context menu

$menuItem1 = New-Object System.Windows.Forms.ToolStripMenuItem -ArgumentList "Hello"
$menuItem1.Add_Click($menuItem1_OnClick)
$menuItem2 = New-Object System.Windows.Forms.ToolStripMenuItem -ArgumentList "Hello Again"
$menuItem2.Add_Click($menuItem2_OnClick)

$contextMenuStrip.Items.Add($menuItem1) # Add option to context menu
$contextMenuStrip.Items.Add($menuItem2)

$menuItem1_OnClick=({ [System.Windows.Forms.MessageBox]::Show("Hello Clicked!") })
$menuItem2_OnClick=({ [System.Windows.Forms.MessageBox]::Show("Hello Again Clicked!") })

$textBox.ContextMenuStrip = $contextMenuStrip # Assuming you've assigned your TextBox instance to $textBox

Hello,

just got it:
$menuitem1.add_click({[System.Windows.Forms.MessageBox]::Show("Hello Clicked!") })
You already wrote it in your first post.
Thanks a lot for your help.
