need to show empty date

[rob mays]

When the datetimepicker loads I dont want any dates to be shown in the textbox please.

how do i do that?

Hello rob mays,

RadDateTimePicker has NullDate support. When you set its Value to its NullDate (NullDate by default is equal to the MinDate), the text you will see in RadDateTimePicker would be set to the NullText. NullText by default is an empty string.

• In order to set the NullDate to a different date than the MinDate, you should set the NullDate of the DateTimePickerElement:

  this.radDateTimePicker1.DateTimePickerElement.NullDate = DateTime.Now;

• In order to set the value to NullDate, call the SetToNullValue method:

  this.radDateTimePicker1.DateTimePickerElement.SetToNullValue();

If you have additional questions, feel free to contact me.

Hello,  I'm having the following issue:

When I trap the delete key on KeyDown I set DateTimePickerElement.SetToNullValue();  As expected the control's value disappears and the text box becomes blank.  The issue is that as soon as the control loses focus the old value re-displays. 

Please help.

Hi Eduardo Molieri,

I suppose that you are using Q3 2010 version.

In this case you should simply call SetToNullValue method and handle the event.

void radDateTimePicker1_KeyPress(object sender, KeyPressEventArgs e)
{

  if (e.KeyChar == 'd')

  {               this.radDateTimePicker1.DateTimePickerElement.SetToNullValue();

 e.Handled = true;

  }
}

Please refer to the attached project.

I hope this helps.

Best wishes,
