Clear RadTimePicker

[Mark]

We are using version 2016.3.1024.40 and i just want to clear the value.  I have tried setting the value = null and that does not work.  Standard controls that would work just fine.  There has to be a simple way to do this.  I have about 20 controls that I need to do this to.  Just want to take the value/text that is displayed and blank it out.

Thanks in advance.

Hello Mark,

The following article shows how you can clear the value: Set null or empty value.

Should you have any other questions do not hesitate to ask.

Yup tried that and NullableValue is not an option for the version i posted.  I have looked at ALL of Teleriks docs and they are no help.  I need some working code for my version.  Something simple would be preferred.

Hi Mark,

This is working with your version. I have attached a small sample project that shows this.

You used the RadDateTimePicker.  I am using the RadTimePicker.

Hi Mark,

This works with the time picker and the specified version as well (see attached video).
