Release R2 2019

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 Scroll down and you will see that an item in the list has been replaced by Item 1 which is now in the list twice.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

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.

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

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.

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.

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.

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.

Currently, the behaviors differ in Android/iOS and UWP. In UWP you can have an empty collection and the LoadOnDemand will trigger when you open the page with the ListView, in iOS/Android you need to have some items in the collection for the LoadOnDemand event to trigger.

Placing a ListView inside a BusyIndicator makes it not responsive to any user interactions. Moving the ListView outside the BusyIndicator solves the problem.
