Hi, 

Is it possible when using the standard DateTimePicker to dynamically change the StartTime/EndTime properties of the Time-part of the control?

I would like the user to be able to click f.ex. 9:00 in the TimePicker, after which this same Time-picker part displays 9:05, 9:10, 9:15, 9:20... until 10:00

(a bit the same like for the Date-picker part - where you can choose the year, then month, then date ....)

Is that something that can be done?

Hi,

You can consider utilizing the SelectionChanged event of the RadDateTimePicker control and manually add set the StartTime and EndTime properties according to the selected hour:

private void RadDateTimePicker_SelectionChanged(object sender, SelectionChangedEventArgs e)
      {
          var selectedHour = ((DateTime)e.AddedItems[0]).Hour;
 
          this.RadDateTimePicker.StartTime = new TimeSpan(selectedHour,0,0);
          this.RadDateTimePicker.TimeInterval = new TimeSpan(0, 5, 0);
          this.RadDateTimePicker.EndTime = new TimeSpan(selectedHour + 1, 0, 0);
      }

 Of course, you might need to further consider the exact approach according to your setup. I suggest you have a look at the following article from our documentation - Clock Items - as setting a custom ClockItemsSource should be useful for you.
