To anyone that can help, I've now exhausted my help
resources and this is one of the last spots that I can
think of to get assistance on this issue.

I'm not sure if I'm just missing the obvious here, but
I'll lay out my problem:

What I have - A Visual Basic.NET (2003) project with a
MDI Container that contains a toolbar.  The toolbar has
four buttons on it Start, Previous, Next, and End.

Next I have a MDI Child that loads into this container
and contains a dataset with a variety of contextbinded
fields.

What I'm trying to do basically is change the position
(i.e. via clicking the next button) of the dataset. Now I
can do this easily if I create a button on the same child
form, in it calling this function:

    Public Sub func_nav_next()
        Me.BindingContext
(objds_main_data, "table1").Position = (Me.BindingContext
(objds_main_data, "table1").Position + 1)
    End Sub

However, when I try calling this same (public, shared)
function from the MDI Container, nothing happens.

Any ideas anyone?

Thank You for any help,
Jessee Holmes

Additional Information:

Just for information, I have made the forms available to
the entire project through this method so I can call
controls from one another.

Public Module globals

    Private g_mdi_child As frm_mdi_child
    Private g_mdi_parent As frm_mdi_parent

    Public Property frm_mdi_child() As frm_mdi_child
        Get
            If g_mdi_child Is Nothing Then
                g_mdi_child = New frm_mdi_child
            End If
            Return g_mdi_child
        End Get
        Set(ByVal Value As frm_mdi_child)
            g_mdi_child = Value
        End Set
    End Property

    Public Property frm_mdi_parent() As frm_mdi_parent
        Get
            If g_mdi_parent Is Nothing Then
                g_mdi_parent = New frm_mdi_parent
            End If
            Return g_mdi_parent
        End Get
        Set(ByVal Value As frm_mdi_parent)
            g_mdi_parent = Value
        End Set
    End Property

End Module

Jesee,

I have a question -   You say that Public Sub func_nav_next() function is
shared, public. If that function were shared, you would have received a
compile error because you are using "Me.BindingContext",  and "Me" can
never be accessed from within a shared function

Also, can you send more detailed code? Where do you access the properties
in the global module? I see that you are not setting the parent property of
 the mdi_child to the parent container.

I tried creating an MDI container with a child form bound to a dataset. I
added a button on the parent form and called the func_nav_next()  function
on the child form, and it seemed to work fine.
