Question

How Can I Make the value of a date time picker value to null when loading a form?
When I am using datetimepicker, it is displaying a default value when the form is loading.
I have set both the minimum and maximum date for datetimepicker.

My Requirement is “to display null value(Nothing) in the datetimepicker so that user have to select date from the datetimepicker”. I refereed so many sites. All those about Custom formats. I have my own idea. i,e Taking a button as Readonly and in the button click event, i can make the datetimepicker as visible.
// in the datetimepicker_DateSelectd Event
Button.text=datetimepicker.value;

But i dint satisfy with this.
Can u please suggest me.

One thing you could do is

dtpConstDate.CustomFormat = " "; 
dtpConstDate.Format = DateTimePickerFormat.Custom;

On value change you could do

private void dtp_ValueChanged(Object sender, EventArgs e) {

  dtp.Format = DateTimePickerFormat.Short; 

}

So the idea is simple you could change the datetime picker format accordingly to achieve your goal.
