If you are using window.open for opening a child window
then you can simply use the following approach:

In Parent Page Create one JavaScript function:-

ParentTest()
{
// do something
}

In Child Page on some event, call the parent funciton
ChildTest()
{
window.parent.ParentTest();
}

It is easy but it requires that Child Form knows Parent Form. This breaks encapsulation concept.

I think you do´nt need do it from parent form.

You are using a modal child form. Then use the DialogResult.

Note that there are some Dialog Result values.
You assign a Dialog Result to each Button on Child Form that terminates the action (Ok, CanCel, Yes ...)

   Dim Result = ChildForm.ShowDialog
   Select Case ReSult
       Case DialogResult.Ok
          Refresh the Dgv
       Case DialogResult.Cancel
          Other Options

Note that when you press a button with DialogResult asigned, ChildForm is closed.

I dont expect someone to just write my code for me, however I just opened VB.NET for the first time, last week, and have poking around since.. is there some sample code you can show me, the code above is where I need the parent refresher
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        'Try
        cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\users\jason\documents\visual studio 2010\Projects\WindowsApplication2\WindowsApplication2\Database1.mdb;")
        cn.Open()
        str = "INSERT INTO customers (customer_fname, customer_lname) VALUES('" & Me.TextBox1.Text & "','" & Me.TextBox2.Text & "')"
        cmd = New OleDbCommand(str, cn)
        cn.Close()
        <!-- THIS IS WHERE I NEED REFRESH CODE -->
        Me.Close()
    End Sub

Open in new window

   Dim Dt as new DataTable, Da as new OleDbDatAdapter(cmd)
   Da.Fill(Dt)
   TheDgv.DataSource = Dt
