Thank you for contacting us.
I've tested the RadDateTimePicker
with time formats. The custom format is set to:
this.radDateTimePicker3.DateTimePickerElement.CustomFormat = "HH:mm:ss";
Then, I set the dateTime to:
this.radDateTimePicker3.DateTimePickerElement.Value = new DateTime(1980, 1, 1, 1, 30, 45 );
After that, on a button click I set the value to:
this.radDateTimePicker3.DateTimePickerElement.Value = new DateTime(1980, 1, 1, 23, 12, 45);
and everything works as it is expected.
The test is made with the standard style of RadDateTimePicker. The issue when the up/down buttons are shown is confirmed and will be addressed in the upcoming Q1 release. RadDateTimePicker,
uses the standard WinForms DataBinding, we have not made any changes to that mechanism.
If you experience more issues with RadDateTimePicker,
please give me more information, or send me a simple project demonstrating the issues to let me test the component.
I'm looking forward to your response.
