vb.net- adding ribbon panel to existing tab

[Eyal.Admon]

Hi Everyone,

I'm trying to add a costume panel to the tools tab in drawing document ribbon for my add-inand keep getting and error.

The line that throws the error is marked below with an arrow

note: I have used the same lines to add a panel to part and assembly document ribbons and it worked just fine.

Thanks

' Get the ribbon.

Dim drawingRibbon As Inventor.Ribbon = g_inventorApplication.UserInterfaceManager.Ribbons.Item("Drawing")

' Get the "Tools" tab.
Dim drawingtoolstab As Inventor.RibbonTab = partRibbon.RibbonTabs.Item("id_TabTools")

' Check to see if the "MySample" panel already exists and create it if it doesn't.
Dim customPanel_drawing As Inventor.RibbonPanel = Nothing

Try
customPanel_drawing = drawingRibbon.RibbonPanels.Item("MySample")

Catch ex As Exception
End Try

If customPanel_drawing Is Nothing Then
'Create a New panel.
customPanel_drawing = drawingtoolstab.RibbonPanels.Add("Sample", "MySample", g_addInClientID)  <-------

End If

i figured it out.

i had a mistake in the line:

Dim drawingtoolstab As Inventor.RibbonTab = partRibbon.RibbonTabs.Item("id_TabTools")

the "partRibbon.RibbonTabs.Item("id_TabTools")" should have been :

drawingRibbon .RibbonTabs.Item("id_TabTools").

stupid mistake...
