You might want to consider using UltraCalendarCombo instead of UltraDateTimeEditor. It's a nicer-looking control, anyway. :)

Hi guys, we managed to solve this problem! 

private void dtpDateOfBirth_ValueChanged(object sender, EventArgs e)
{
    dtpDateOfBirth.DateTime = (DateTime)dtpDateOfBirth.Value;
}

When user selects the date in the control and deletes it manually then null refeerence exception appears. 

private void dtpDateOfBirth_ValueChanged(object sender, EventArgs e)
{
            if (dtpDateOfBirth.Value != null)
            {
                dtpDateOfBirth.DateTime = (DateTime)dtpDateOfBirth.Value;
            }
        }

I know this is an old thread but hopefully I can still get some help.  What would be the equivalent in VB.net, I cant seem to get anything to work that is along the same line as the mentioned code above.  I am new to VB.net so any help would be appreciated.

Pretty much exactly how it was shown above.

Private Sub UltraDateTimeEditor1_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles UltraDateTimeEditor1.ValueChanged

If Not UltraDateTimeEditor1.Value Is Nothing Then

UltraDateTimeEditor1.DateTime = CType(UltraDateTimeEditor1.Value, DateTime)

End If

End Sub

Hi

Can u send me ur code or ur application sample using that code?

Thanks, I was close just didnt realize I could cast as datetime.  Didnt seem to fix the invisible dates though.

 The VB equivalent would look something like this:

    Private Sub UltraDateTimeEditor1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dtpDateOfBirth.ValueChanged
        If Not dtpDateOfBirth.Value Is Nothing Then
            dtpDateOfBirth.DateTime = CType(dtpDateOfBirth.Value, DateTime)
        End If
    End Sub
