Dispose will work correctly if you construct the XtraGridBindingManager using the constructor which accepts an IContainer, e.g.,

   myXgbm = new XtraGridBindingManager(this.components);
 
This is actually the constructor used by the XtraGridBindingManager designer when it auto-generates code.  Using this constructor, dispose will also automatically be called when the container is disposed.
 
(The fact that Dispose does not work correctly when other constructors are used is a bug.)

Using : DevForce 3.6.7.1 & DevExpress 9.1.3

I get an exception when trying to dispose a IdeaBlade.UI.WinForms.DevExpressControls.XtraGridBindingManager object :

   à System.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
   à System.Collections.Generic.Dictionary`2.FindEntry(TKey key)
   à System.Collections.Generic.Dictionary`2.TryGetValue(TKey key, TValue& value)
   à IdeaBlade.UI.WinForms.DevExpressControls.XtraGridColumnBinder.UnRegisterEvents(RepositoryItem pRepositoryItem)
   à IdeaBlade.UI.WinForms.DevExpressControls.XtraGridBindingManager.Dispose(Boolean disposing)
   à System.ComponentModel.Component.Dispose()

How to properly dispose XtraGridBindingManager object?
