The scenario in which the issue is reproducible is when one of the tabs of a RadTabView contains a RadSideDrawer. Switching the view a couple of times causes an exception to be thrown when trying to open the tab that contains the RadSideDrawer. 

The issue is reproducible in UWP and Android.

Available in minor release 2018.1.0315. It will also be available in the R2 2018 release.

Consider implementing a Completed event that is raised when the Completed event of the entry is raised. This is in order to accommodate customer needs to get notification for enter pressed.

Hi,

On Android, I am using a DataTemplateSelector and a DataTemplate that has a switch on it that the user can press. When the user presses the switch the ListView starts corrupting the data in the list. The item being interacting with starts appearing in other locations on the list.

This issue can be reproduced in the Telerik SDKBrowser project.

Select the following : ListView -> Cell Types -> Template Cell Selector - Xaml

Mark Item1 as special using the button. Scroll down and you will see that an item in the list has been replaced by Item 1 which is now in the list twice.

Regards

Anthony

Release 2019.2.603.360 (R2 2019 minor release)

The RadCalendar DayView.EventView get stuck in a shifted position. This only occurs on iOS.

 

Steps to reproduce:

1. Load calendar.

2. Slowly slide the event view (lower portion) either right or left until the time labels (1am, 2am, etc.) are no longer in their starting positions.

3. Without releasing the scroll, tap the button to change the view to Month view mode.

4. Tap the button to change back to Day view mode.

5. Observe that the entire events view is still shifted and will remain so until the RadCalendar control is destroyed and a new one is created.

 

Attached are pictures showing the correct view and the incorrect view. Also, a sample project is attached that can be used to replicate this issue.

I have attempted to use a custom renderer to manually reset the events view, but nothing seems to work.

private async void RecentEvents_LoadOnDemand(object sender, EventArgs e)
        {
            //RecentEvents.EndRefresh(false);
            var vm = (HomePageViewModel)ViewModel;
            await vm.GetRecentEvents(true);
         
        }

Issue is :  After first time "Load More" button get disabled. (Doesnt seem to click) . Soon after loading it works.  Once it is clicked it loads the new items as well. After that the "Load More" but is not clickable. Atleast click doesnt seem to trigger the RecentEvents_LoadOnDemand event.

Any issues which could be the reason for this? 

Thank you in advance
