Add a RadTimePicker to your project and select new time from the popup.
Expected: The clock element inside the popup should be updated accordingly to the newly set value.
Actual: The clock element remains unchanged. It is necessary to close and open the popup again.
Workaround:
private void RadTimePicker1_ValueChanged(object sender, EventArgs e)
{
this.radTimePicker1.TimePickerElement.PopupContentElement.ClockElement.Value = this.radTimePicker1.Value;
}
