Hiding Null Records on Command

My question is fairly straight forward and hopefully simple.

I've got a database that has a long list of part numbers, and some items without part numbers. What i'd like to d开发者_StackOverflowo is have a command button or Radio button that when activated, hides these null records, and when pressed again, shows them once more.

I can give more detail if needed

Thanks for any help!

Here is an example of using the Filter (same as using of out-of-the-box filtering capability from the Access/Office menu):

Setup:

• Table (e.g. Parts):

• Form (PartsForm):

• Event handler for the Checkbox (OnClick):

  Private Sub DisplayAllFilter_Click()
  
  Me.Filter = ""
  
  If Me.DisplayAllFilter.Value = False Then
      Me.Filter = "[PartNumber] is not null"
      Me.FilterOn = True
  Else
      Me.FilterOn = False
  End If
  
  End Sub
  

Result would be something like these:
