title: VB.NET - Date Time Picker saves current date by default, even if no date is chosen
body: <p>I have a date picker named 'paidDateDp' in my form. My configuration is as below</p>
  
  <p>Property Setting:
      Format="Custom"</p>
  
  <pre><code>Private Sub paidDateDp_ValueChanged(sender As Object, e As EventArgs) Handles paidDateDp.ValueChanged
          paidDateDp.CustomFormat = "dd-MMM-yyyy"
      End Sub
  </code></pre>
  
  <p>While executing, I see the paidDateDp value is blank. Even if I dint choose any value, when I attempt to save the details of the form to MSAccess using my Oledbadapter query, by default, the current date is getting saved against the paidDate column of my access table.</p>
  
  <p>How to save empty date to my access table from my datetime picker, provided no date is selected?</p>
  
  <p>Someone please suggest me.</p>
