                        </DataTemplate>
                    </telerikDataControls:RadListView.LoadOnDemandItemTemplate>
                </telerikDataControls:RadListView>

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

If you have an ItemTemplateSelector defined and switch the templates at runtime, any bindings inside the template are broken.

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.

When you have some kind of image - CachedImage, FFimage, XF Image, within the ItemTemplate of the RadListView and you want to use the ItemSwipe functionality - the items constantly flicker. 

If you set a constant height to the listView item - the issue is not observed:

<dataControls:RadListView.LayoutDefinition>
    <listView:ListViewLinearLayout ItemLength="50"/>

</dataControls:RadListView.LayoutDefinition>

Release R2 2019

If you have a more complex HeaderTemplate containing input controls, each button placed after a certain position does not fire its Click event.  If a button is placed at the top of the template, it functions properly.

Hello,

 

I have a class, a collection of which is displayed in RadListView. If the class has a static property, no single item is displayed in UWP. In Android and iOS it works without this problem.

 

Regards,

Franz.

In a scenario when LoadOnDemandMode is Automatic, SpanCount >1 and ItemLength is large the loading indicator has different size depending on its position in the columns, as it takes up all of the available space.

With the previous release (2018.3.1) displaying many items (10000+) with groups and sorting took less than a second. With the latest release (2019.1.1) the time is increased to several seconds on the same device.

When an ItemTemplateSelector is applied to the ListView, the item must be refreshed on each property change, to give the ItemTemplateSelector a chance to re-evaluate its logic. This causes the item to flicker on iOS, because it appears with its default size initially, and then it gets resized during the measure/layout phase. Specifying a fixed ItemLength in the LayoutDefinition can work around the problem, if dynamic item sizing is not needed.

The control listen for changed to re-filter, so when any property is updated, there is a side effect on iOS - the entry used for editing loses focus.
