your mdi child has an MDIParent property.
But you have to cast it properly before using:

I get an Error when making this call:
   ((MainForm2 )this.MDIParent).AddCamerastoButton();

'SW24RC_DevEx.ChildMDItestForm' does not contain a definition for 'MDIParent'      

- Strange this is "Intellisense" allows me to choose the MainForm2.AddCamerastoButton method.
- ChildMDItestForm = my Child form
- MainForm2 = my Parent Form
- AddCamerastoButton() method is on my MainForm2 = MDI Parent method
