When you try to swipe several items at once by using more than 1 finger - the items are stuck and the space where the ItemSwipe content should be present is left blank. The issue can also be observed if you swipe items very fast. 

When LoadOnDemand feature is enabled and you're using LoadOnDemand event to add more items asynchronously, the loading indicator is not shown and it is not clear to the end user that any action is currently processed. 

NullReferenceException is thrown when Singleton ViewModel is used

Expose GroupHeaderTemplate Selector property as ItemTemplateSelector property

When any control (Frame, for example) with applied Margin is placed inside GroupHeaderTemplate of the ListView, the Margin value is not respected on iOS.

Provide a solution for Re-positioning of vertical scroll bar on IOS, or hide it at all.

Hello,

Right now, I use SyncFusion ListView because of several limitations of the RadListView :
- no way to make the ScrollItemIntoView animated. It results with a UI which doesn't look smooth or moden.
- no way to remove the highlight on item tap even if selectionMode is set to none. My users think there is a hidden action made

Am I missing something ? I would like to get rid of SyncFusion and only keep Telerik. But the ListView is by far the control I use the most and I can't really make regression on that part. Because I moved to SyncFusion due to user's feedback that don't like the highlight and that the scroll wasn't smooth and so the app looks like slow / not modern enough.

Do you think those features can be added in the roadmap ?
It would be nice to compete a bit more with the SyncFusion ListView which is very nice to use from a developper point of view. Althought the RadListView is great too. It's just that I'm waiting for improvment since a year.

 

PS : the documentation is lacking of scrolling / highlight part saying it's not possible or require a custom renderer and then, giving the first steps to create those renderers. I can't be the only one to struggle with this.

 

Thanks a lot

The UI for UWP ListView has a great feature that lets you define a string (or a DataTemplate) that the ListView will show where there are no items in the ItemsSource via the EmptyContent property.

Please add this for the UI for Xamarin RadListView.

Activating the ItemHold event of an item in a list view requires holding down an item for a while.  On a physical/virtual Android device and a virtual iOS device, this can be done by holding down the mouse/finger lightly on an item for a short period of time.  However, on a physical iOS device (I am using a physical iPhone 6s to test this), holding down the item lightly with my finger won't activate the ItemHold event, and I have to hold the item really hard on the screen in order to activate it (similar to using 3D Touch / Force Touch, and I cannot reliably activate the ItemHold event possibly because my force is sometimes not hard enough).  I noticed this behaviour on the physical iOS device since the ItemHold event got implemented in early 2018.

I created a simple application to demonstrate the issue.  The app displays an alert when the user taps/holds an item in the list view.  On a physical iOS device, holding down an item in the list view requires the user to press the item very hard on the screen.

Thanks,
Kori

if the swipe content of the cells are buttons, dragging the buttons up and down will keep the swiped cells in the same position of the screen, creating unexpected animations and showing the entire swipe content of the cell.

I would like to animate the expand and collapse effect of the grouping on ListView control.

The bug can be reproduced on iOS 13 only. It is not reproducible on earlier versions of iOS. Run the attached project on iOS 13 device or Simulator to reproduce it.

Sometimes when focusing an entry and the onscreen keyboard shows up, the ListView is not scrolled correctly, so the entry is overlapped by the keyboard. The ListView layout appears messed up after that and the scrolling does not behave correctly.

When RadListView is setup to load its items on demand and the LayoutDefinition is GridLayout with SpanCount set to 2 or more, the Footer Template does not take all the width, it expands only to the Width of the first column.

ListViewLoadOnDemandCollection method is not triggering in iOS automatically when there is a need to display the items on the screen. We have to manually scroll the list view then the ListViewLoadOnDemandCollection triggers and give further data to show. 

Things are working fine on Android platform.

Does the RadListView control support snap scrolling? I could not find any documentation on this. 

• Snap scrolling is when a user swipes to initiate a scroll, the end position of the scroll can be controlled so that items are fully displayed. This feature is known as snapping, because items snap to position when scrolling stops.

When the SwipeOffset property is set at a later stage, the cell will be moved beyond the offset. 

Currently if RadListView is grouped and reorder enabled, users can drag items to different groups - the drag and drop to different groups can be prevented only on ReorderEnded event. Provide a way to prevent the user from visually dragging the item past the bounds of the outer group.

Changing a property on an item that is involved with grouping and sorting and then removing and re-adding the item to the collection results in the list being in an invalid state (e.g. duplicate items, incorrect template, etc.)

Error message can be reproduced on iPhone 11 Simulator iOS 13.6

When ListView is grouped with sticky group headers enabled, and items have dynamic size in order to adjust their content, the ListView is not rendered correctly when scrolled.
