  There is a way to set the minute step?
  
  i don’t want the full list (1,2,3,4,5,6…) but instead i would this short list (0,15,30,45)

  Thank’s

  Hi,
  
  You can find the minutes combobox and change its ItemsSource.
  
  See the below code:

  <c1:C1DateTimeSelector Height="60" x:Name="dts" />
  

  public sealed partial class MainPage : Page
      {
          List<int> data = new List<int> { 0, 15, 30, 45, 60};
          public MainPage()
          {
              this.InitializeComponent();
              Loaded += MainPage_Loaded;            
          }
  
          private void MainPage_Loaded(object sender, RoutedEventArgs e)
          {
              this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Low, () => 
              {
                  var minute = dts.GetChildren<ComboBox>().Where(el => el.Name.Equals("MinutesList")).FirstOrDefault();
                  if (minute != null)
                  {
                      minute.ItemsSource = data;
                      minute.ItemTemplate = null;
                      minute.SelectedIndex = 0;
                  }
              });
              
          }
      }
  
      public static class Extensions
      {
          public static IEnumerable<DependencyObject> GetChildren(this FrameworkElement elem, bool includeSelf = true, bool recursive = true)
          {
              if (elem == null) yield break;
              if (includeSelf) yield return elem;
  
              FrameworkElement current = elem;
              for (int i = 0; i < VisualTreeHelper.GetChildrenCount(elem); i++)
              {
                  var child = VisualTreeHelper.GetChild(elem, i);
                  yield return child;
                  if (recursive && child is FrameworkElement)
                  {
                      foreach (var item in (child as FrameworkElement).GetChildren(false, true))
                      {
                          yield return item;
                      }
                  }
              }
          }
  
          public static IEnumerable<T> GetChildren<T>(this FrameworkElement elem) where T : FrameworkElement
          {
              return elem.GetChildren().Where(e => e is T).Select(e => e as T);
          }
      }
  

  Thanks,

  Hi
  
  thanks for your reply but not works fine
  
  I insert the TimeSelector into a C1TabControl
  
  it works only in the first TabItem
  
  in the others TabItem not works because this line
  
  Dim childrenCount As Integer = VisualTreeHelper.GetChildrenCount(parent)

  return 0

  Hi,
  
  It might be a limitation to implement this request in an easy way. As investigated, I provided a workaround to make this request. Please refer to attached sample.

  Thanks,
