Save the menu item in any sort of structure, or set it as data for any
accesible object and use gtk_widget_set_sensitive(menu_item, FALSE)

Where is this context menu attached ?

If it's attached to the panel applet It won't work. Your dialog won't be
children of the applet so the modal state in the dialog won't affect the
applet at all.

Frankly I don't completely understand you.

If you need a modal dialog try gtk_dialog_run()

But this won't disable a panel applet. You should set insensitive all
items you want to be disabled on dialog's construction and unset them on
it's destroy.
