   // Show information about Back button.
   MessageBox.Show(myString, "Back button information");
}

Private Sub CallBackButtonClick()
   AddHandler myDataGrid.BackButtonClick, AddressOf Grid_BackClick
End Sub


' Raise the event when 'BackButton' on child table is clicked.
 Private Sub Grid_BackClick(ByVal sender As Object, ByVal e As EventArgs)
     ' String variable used to show message.
     Dim myString As String = "BackButtonClick event raised, showing parent table"
     ' Show information about Back button.
     MessageBox.Show(myString, "Back button information")
 End Sub

Remarks

The Back button becomes visible when a child table is displayed. Clicking the button will cause the grid to display the parent table.
