App hangs when ListView uses dynamic size for the cells: 

When using load on demand mode manual, and collapsing groups, one item left not collapsed.

If the ListView ItemTemplate contains more elements and you try to load more items (>15 items), there is a crash on iOS related to layout arrangements.

To workaround the issue, set explicitly ItemLength:

<telerikDataControls:RadListView.LayoutDefinition>
       <telerikListView:ListViewLinearLayout ItemLength="400" />
</telerikDataControls:RadListView.LayoutDefinition>

Go to QSF ListView->selection example 
1. Select the 2nd row and swiped it to the left
2. While the row above is still in the left-swiped mode with its red delete button still visible, click on a DIFFERENT  row (say the 3rd row) AND scroll the ListView.

Video attached. 

When Group Header template is used and the visibility of an element in the template is changed, the template does not recreate as expected. 

For example add entry /editor in the template and change its visibility

On iOS the editor/entry overlaps the group header and cannot type in it.

On UWP : The editor is visualized as expected but then we change its visibility to false, the space for the editor is still visible. The group header does not layout as expected.

Solution:

You have to collapse/expand the group header so the template in the group header to layout as expected

When adding swipe content, it block the button to be clicked when the items in the cell matches the swipe offset value, 

a. reduce the swipe offset.
b. place the minus button further to the left, so the button width to match the ListView swipe offset

Sample setup:

<telerikDataControls:RadListView x:Name="listView"
                                    IsItemSwipeEnabled="True"
                                    SwipeOffset="90, 0, 0, 0"
                                    SwipeThreshold="20"
                                    ItemsSource="{Binding Source}"
                                    SelectionMode="None">
    <telerikDataControls:RadListView.ItemTemplate>
        <DataTemplate>
            <listView:ListViewTemplateCell>
                <listView:ListViewTemplateCell.View>
                    <Grid ColumnDefinitions="*,90">
                        <!--  >> changed second row to 90 pixels, which is swipe offset  -->
                        <Label
                            FontAttributes="Bold"
                            FontSize="16"
                            Text="{Binding Sender}"
                            TextColor="Black" />
                        <StackLayout Grid.Column="1" 
                                        Orientation="Horizontal">
                            <Button
                                Clicked="Button_Clicked_1"
                                Text="+++"
                                TextColor="Gray" />
                            <Button
                                Clicked="Button_Clicked"
                                Text="---" />
                        </StackLayout>

                    </Grid>
                </listView:ListViewTemplateCell.View>
            </listView:ListViewTemplateCell>
        </DataTemplate>
    </telerikDataControls:RadListView.ItemTemplate>
    <telerikDataControls:RadListView.ItemSwipeContentTemplate>
            <DataTemplate>
                <Grid
                            Margin="0"
                            Padding="0"
                            ColumnSpacing="0"
                            RowSpacing="0">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="90" />
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>
                    <telerikInput:RadButton
                                Grid.Column="0"
                                Margin="0"
                                BackgroundColor="Red"
                        Clicked="RadButton_Clicked"

                                FontSize="Medium"
                                Text="&#xf1f8;"
                                WidthRequest="90" />

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

is thrown when navigating to another view using ListView SelectedItem and removing the view where the ListView is placed. 

Workaround:

Instead of removing the view, change the view visibility.

On Android when adding new item to the ListView which is RadExpander with RadListView inside it, and when removing and adding item with different length the cell is not measured correctly. 

On iOS the ListView cell are not automatically sized. one height for cell is used

On UWP when adding the second item the app crashes with "System.ArgumentException: An item with the same key has already been added. Key: SDKBrowser.Examples.ListViewControl.GettingStartedCategory.GettingStartedExample.Product\r\n   at System.ThrowHelper.ThrowAddingDuplicateWithKeyArgumentException(Object key)\r\n   at System.Collections.Generic.Dictionary`2.TryInsert(TKey key, TValue value, InsertionBehavior behavior)\r\n   at Telerik.UI.Xaml.Controls.Data.ListView.Model.BaseLayoutStrategy.RecycleLocally()\r\n   at Telerik.UI.Xaml.Controls.Data.ListView.Model.BaseLayout"

When applying multi-level grouping, then change the items group keys, the new groups are added but the old ones are still visible in the list view, and from child group they become parent group. 

Workaround:

clear the group descriptors before changing the items and then re-add the group descriptors again

when we try to add a dynamic AutomationId in each item of the list (something like AutomationId="{Binding Id}"), the AutomationId is not provided to the elements we see in the appium inspector. 

Works with fixed values

Telerik RadListView with two Columns - they are Thumbnails with a tap gesture. When we change the Spancount to 1 there is no right border line but when set back to 2 it shows as the screenshot on IOS, 

The issue happens on iPhone 11, XR, devices with a notch, and when ListViewGridLayout is with SpanCount="2".

Workaround: Set the background color of the ListViewItemStyle to Transparent

<telerikDataControls:RadListView.ItemStyle>
    <telerikListView:ListViewItemStyle BorderWidth="0" 
                                        BackgroundColor="Transparent"/>
</telerikDataControls:RadListView.ItemStyle>
