Is there a way to customformat DateTimePicker to only allow users to select M-F?

Thank you

— and asked for clarification; the short answer is that the DateTimePicker’s format cannot prevent weekend dates. The practical solutions are to (A) prevent/adjust weekend picks on the client side (so users can’t pick them in the UI), and/or (B) always validate server-side and reject weekend values. Below are concise, immediately usable approaches for WinForms and for ASP.NET pages.

WinForms (VB.NET): handle the control events and correct a weekend selection. Use a guard flag to avoid recursion when you set the Value programmatically.

Private _skipFix As Boolean = False

Private Sub DateTimePicker1_CloseUp(sender As Object, e As EventArgs) Handles DateTimePicker1.CloseUp
    If _skipFix Then Return
    Dim d As Date = DateTimePicker1.Value.Date
    Select Case d.DayOfWeek
        Case DayOfWeek.Saturday
            _skipFix = True
            DateTimePicker1.Value = d.AddDays(-1) ' go back to Friday
            _skipFix = False
        Case DayOfWeek.Sunday
            _skipFix = True
            DateTimePicker1.Value = d.AddDays(1) ' move to Monday
            _skipFix = False
    End Select
End Sub

ASP.NET / web pages: use a client calendar that supports disabling days (jQuery UI datepicker has beforeShowDay / noWeekends) and also validate on the server.

$('#<%= txtDate.ClientID %>').datepicker({
  beforeShowDay: $.datepicker.noWeekends
});
Protected Sub cvDate_ServerValidate(source As Object, args As ServerValidateEventArgs)
  Dim d As Date
  If Date.TryParse(args.Value, d) Then
    args.IsValid = (d.DayOfWeek <> DayOfWeek.Saturday And d.DayOfWeek <> DayOfWeek.Sunday)
  Else
    args.IsValid = False
  End If
End Sub

Notes: account for locale-specific weekends if your app is global; always keep server-side validation as the authority. For reference on the .NET DayOfWeek enum and the WinForms DateTimePicker see the Microsoft docs: DateTime.DayOfWeek and DateTimePicker (Windows Forms). For web pickers see the jQuery UI datepicker beforeShowDay option.

I'm looking to have a datetimepicker custom format that allows a user to only select Monday thru Friday and have the weekends exempt from selection.

Sorry for the confusion.
