hi,

is there any way to raise an event when user tap on Week Number Cell Type ?

 

"CellTapped" not firing when click on week number cell.

Can we add custom event for specific cell type ? , if YES How ?

Inside renderer or in  CustomizationRule

I would like to say that recently we purchased Telerik.UI.for.Xamarin and added Telerik Nuget in our app. It works fine after integration and configured with our app. But App build fails on Xamarin Mobile Center (https://mobile.azure.com) with Telerik.UI.for.Xamarin. This happens when we try to create build.

Error: System.InvalidOperationException: Unable to find version '2017.1.10301.12' of package 'Telerik.UI.for.Xamarin'.

Full details are below:

Currently in the android version the day view of the calendar there seems to be a bug. When there is an all-day appointment selected it will normally display the all-day header appointment item. If we select another date and go back to the date before it will not always show the all-day header item. This can be seen in the images that are attached to this post.

hi,

In multi day view mode if user swipe left or right calendar changes date by its own (may be force put on calendar)

I need to detect user swipe gesture, below codes aren't firing

 

<telerikInput:RadCalendar.GestureRecognizers>
               <SwipeGestureRecognizer Swiped="SwipeGestureRecognizer_Swiped" Threshold="10"/>
           </telerikInput:RadCalendar.GestureRecognizers>

any work around ? even in renderers ?

hi,

when user swipe day calendar, i am fetching appointments from server in calendar DisplayDateChanged event, those server calls are under "await". This take some time to complete and then use those data to set calendar appointment source, then DisplayDateChanged event automatically fires and setting date to previously where it was. so calendar can not scroll to where user wants. This may be because of time taken to fetch data or again setting appointment source of calendar.

can reproduce using following code.

private async void daycalendar_DisplayDateChanged (object sender, Telerik.XamarinForms.Common.ValueChangedEventArgs<object> e)
       {
          
 
           await longrun();
       }

 

private async Task longrun()
      {
          ObservableCollection<testmodel> items = new ObservableCollection<testmodel>();
          for (int i = 0; i < 10; i++)
          {
              var item = new testmodel
              {
                  Title = "Meeting with Tom" + i,
                  Detail = "Sea Garden",
                  StartDate = DateTime.Now,
                  EndDate = DateTime.Now.AddHours(1),
                  Color = Color.Tomato
              };
              items.Add(item);
               
          }
       
          weekcalendar.AppointmentsSource = items;
      }
  }

 

testmodel as is this 

public class testmodel : IAppointment, INotifyPropertyChanged

 

tested only in Android. Any solution ?

How do I change which timespan the day view is showing when it is opened?

I would like it to scroll to the current time when opened, instead of staying at the minimum time for that day.

Also, has anyone implemented a line showing the current time?
