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.

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.

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

Cell height is not being adjusted to show all the content. the text overflow and it overlap the cell below. It seems that dynamic size is not respected.

With Automatic LoadOnDemand, once all items are loaded and IsLoadOnDemandEnabled is set to false, when I scroll till the end the loading indicator keeps flickering on knowing that no more items are called.

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.

When swiping a cell, the swipe content of the cell will be shown if the swipe threshold is reached.  On iOS, the swipe content of another cell can be shown immediately by swiping another cell (which is an expected behaviour).  However on Android, when the user swipes another cell, the swipe content of the other cell isn't shown (while the swipe content of the first cell becomes hidden).  The user has to swipe the other cell again to show the swipe content.

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.

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.

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

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

Provide a GroupHeaderStyle which will allow users to apply background color and border styling to the group headers in a similar way as ItemStyle.

GroupHeaderTemplate has a default gray background applied and setting Transparent does not take any effect.

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

RadListView item height is not adjusted to fit the content in the cell on iOS 13 Beta.

When you initiate a swipe gesture and the SwipeContentTemplate is shown,  changing the device orientation from portrait to landscape, does not update the ListView layout and the swiped item width is incorrect.

Java.Lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

For example change the IsPullToRefreshEnabled state on button click, when button is pressed several times, exception is throw.

Expose GroupHeaderTemplate Selector property as ItemTemplateSelector property

When using DataTemplates on the ListView for Android, items are constantly redrawn when data shown on the template is updated, this is obvious to the user as it flashes and doesn't look great. Note that the native ListView does not do this.

Hi,

I rolled my app with the ListView out to production and are getting 8+ crashes a day from 140 users with the above issue. I have included a stack trace. I cannot find the steps to reproduce the issue in development. I have rolled back to using the native ListView as this does not crash the app.

Attached is an example project to see what I am doing in general terms, but I have not been able to reproduce this crash in it.

My guess is that a DataTemplate is not being cleaned up properly and when the data behind is changed it attempts to access the control that represented the data in the DataTemplate.

Anthony
