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

Value is not applied correctly when StringFormat property is used (N format specifier): For example

 <telerikInput:RadNumericInput StringFormat="{}{0:N0}"
                                               Value="{1234.56543}"/>

 Workaround:

use F format specifier instead of N format specifier

SelectionChanged starts calling twice when appointments collection is changed at runtime from within the event.

The problem occurs when I update the Events property on either of the events DisplayDateChanged or SelectionChanged. It seems these events are triggered another time, sometimes, when the AppointmentSource gets refreshed. I say sometimes because you can navigate through the weeks as normal, but as some points you notice something went wrong. Here’s a list of what I have encountered so far :
When sliding through the weeks from the days header, let’s say the selected day is a Monday, the next weeks would have the Monday selected as expected. Then a random week would have an other selected day (Friday). It would happen randomly until some weeks get skipped completely.
When sliding through the weeks from the days header, let’s say the selected day is a Monday, the next weeks would have the Monday selected as expected. If I touch the Friday box,  the selected date gets initially updated  to Friday and then a random day between Monday and Friday gets selected.
When sliding through the weeks from the days header, the calendar gets stucked on a random week, and sliding forward or backward through the days header just put you back to the same week. In this case the only way to move to the next/previous week is to slide through the time slot.

Hi

 

I have a radcheckbox whose checked value is set on my view model, it is bound oneway. My View model implements INotify. 

When my viewmodel updates the property, the ui does not update. If i set the mode to TwoWay the ui reflects accordingly. I have a converter linked to this same property on another object hence I can't set TwoWay Binding to achieve this(Not included in the sample). The checkbox will just be displaying a state and never be updated by the user

 

I have tested on iOS and UWP. Have not verified on Android currently, but will require this in future.

Attached is a sample project.

When entering a value into an entry in the TemplateCell it is not scrolling up the ListView to allow view of the entry.  This causes the soft keyboard to overlap the entry and the user cannot view what they are entering.

TelerikFont.GetUseEmbeddedFont(this);

I am Lazy Loading a document in a TabViewItem on the RadTabView Control. Here are the steps.

 

1. My Page opens and I am on my Main Tab.

2. The user has two Bottom Menu Options, one of them is for a view of a Document.

3. The user selects the Document Tab Option, and the I fire an Async operation that Loads a Byte Array that the PDFViewer is bound to. This loads fine. The document successfully loads in the viewer.

4. The user goes back to the Main Tab

5. The user then selects the Document Tab Option again, the Byte Array is already loaded so I do not Load it again in my ViewModel. So, I am not updating the Source Property on the PDFViewer again once it is loaded. I also tried just reloading the document with the same results.

The application just crashes. My guess is the Rendering or Re-Rendering of the Pdf Document between Tab Selections and there is someting 

 

If the document is never loaded, the app does not crash. However, once I load the document in the PDFViewer that exists on a Tab, the Application will crash if the user moves between tabs.
