SfListView inside SfAccordion scrolling problem

[Tomasz]

Hello!

I've been trying to use SfListView inside SfAccordion, but when I load the ListView with data, the list doesn't scroll. The scrollbar seems to be visible while the list is first shown, but the scrolling doesn't work for it.

If I put the whole Accordion inside ScrollView, then the page is scrolling property, but the list inside Accordion still doesn't want to scroll.

I've verified the same against the Exapnder control, and the list contained in the expander works as expected, using the same data.

I've tried using sample code provided in other thread, that can be downloaded here, by replacing the ItemsSource with my own data, and that didn't work either.

I've also updated to latest version of Syncfusion components, which at the moment is 17.4.0.43.

If that changes anything, the Accordion is loaded inside ContentView, instead of a ContentPage in first place, and the bindings seems to be okay, since the list displays the expected data.

                            <sflistview:SfListView x:Name="listView" FocusBorderThickness="0" IsScrollBarVisible="False" ItemSize=" 80" BackgroundColor="LightGray" 

                                    ItemSpacing="3" ItemsSource="{Binding ContactsInfo}"> 

                                <sflistview:SfListView.ItemTemplate> 

                                    <DataTemplate>

                                        </StackLayout> 

                                    </DataTemplate>

Thanks for the workaround. I'll be also waiting for an update :)

Hi Tomasz, 

 

Sorry for the inconvenience caused. 

 

We have checked the reported use case with source from our end. We would like to let you know that as per implementation the behavior is defined as if you load Scrollable content in Accordion content then accordion assign screen height to its content. Hence looks like the items in content presenter which are in out of view not scrolled to view. 

 

So, we suggest you to set HeightRequest for the element inside Accordion content to fix the issue as we have mentioned in our previous update.
