how to identity if user clicked on a date in DateTimePicker calendar

Question

I don\'t want the date to change when user clicks out of the calender without clicking on a date. The problem is One Date is always selected when the datepickercalendar open

An old thread but maybe someone finds this useful... If you're looking for DTP that opens "blank" and selects date only If user selects It, then this is (in my opinion) best and simplest option:

Private Sub Form_Load(sender As Object, e As EventArgs) Handles Form.Load

        DTP_Example.Format = DateTimePickerFormat.Custom
        DTP_Example.CustomFormat = " "

End Sub

 Private Sub DTP_Example_ValueChanged(sender As Object, e As EventArgs) Handles DTP_Example.ValueChanged

        DTP_Example.Format = DateTimePickerFormat.Long

 End Sub

 Private Sub DTP_Example_KeyDown(sender As Object, e As KeyEventArgs) Handles DTP_Example.KeyDown

        If e.KeyCode = Keys.Delete Or e.KeyCode = Keys.Back Then
            DTP_Example.Value = Now
            DTP_Example.Format = DateTimePickerFormat.Custom
            DTP_Example.CustomFormat = " "

        End If

    End Sub

This way you have DTP "blank" on open, and displays date If you select some. Also you can delete dates with "Backspace" or "Delete" keys and even select same date as before, which makes DTP simmilar behavior like combobox/textbox. Same "Backspace" behavior as in textbox/combobox can be achieved too, with a little more coding (using another Textbox to manually enter Dates), but in my opinion this is good enough. Cheers
