TimePicker - Null Value

[Doug]

I'm storing a DateTime in XML to tell an applicaton when it will shut down.  I intend to use the value of "01/01/0001 00:00:00" to mean that we have no shut down scheduled.  On the form that will get and set this value I am using two controls, a DateTimePicker and a TimePicker, to work with the value.  (I'm open to other options.)

You already taught me how to handle the DateTimePicker so I'm initializing that control like this:

dtpShutDown.NullDate = Convert.ToDateTime("01/01/0001");
dtpShutDown.NullText = "";
dtpShutDown.Value = Convert.ToDateTime("01/01/0001");

I'm not quite there with the equivalent for the time picker.  This gives me the "00:00 AM" text:

tpLogin.NullText = "";
tpLogin.Value = Convert.ToDateTime("01/01/0001 00:00:00");

I would like some way to just blank out the whole value.

I'm working with options while I wait for your response.  A single DateTimePicker with a custom format to include the time may work out better than I had initially thought.  (Regardless, I would like to know how to set the null time for the TimePicker.)

Thank you,
Gary

Hello Gary,

Thank you for contacting Telerik Support.

RadTimePicker.Value's type is DateTime? and allows null as value. Thus, you can obtain an empty RadTimePicker:

radTimePicker1.NullText = string.Empty;
radTimePicker1.Value = null;

I hope this information helps. Should you have further questions, I would be glad to help.
