There seems to be a difference between the normal .NET date picker and the MM Date Picker

I can use the following to format a return string:
Private Sub DateTimePicker_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
editReqdate.Text = DateTimePicker.Value.ToString("d")
End Sub

Private Sub MmDateTimePicker1_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles MmDateTimePicker1.ValueChanged
editReqdate.Text = MmDateTimePicker1.Value.ToString("d")
End Sub

The second version with the MM control gives me an error:
"'Public Overridable Function ToString() As String' has no parameters and its return type cannot be indexed"

Do I need to use the MM Date picker in my MM form, or can I just use the standard control?

Or is there another way to set the syntax for the MM Date Picker?

Thanks.
