Unable to scroll using arrow keys

[Sree Sundaram]

I have an SfListView control that I am unable to select by scrolling up and down using the arrow keys. I have to move my mouse instead to select the item. Is there a setting that I am missing?

Hi Sree Sundaram,

 

We suggest to set the AllowKeyNavigation property to true to scroll using arrow keys with selection. Please refer the attached code snippet for your reference.

 

Code snippet: 

<syncfusion:SfListView x:Name="listView"

                         AllowKeyboardNavigation="True"

                         SelectionGesture="Tap"

                         ItemsSource="{Binding MusicInfo}"

                         SelectionMode="Single"

                         ItemSpacing="3"

                         IsStickyHeader="True"

                         ItemSize="70">

 

 

 

Please refer the below user guide for Selection using KeyNavigation in SfListView.

Please let us know if you need further assistance.

Here is the Nuget version:

    <PackageReference Include="Syncfusion.Xamarin.DocIO" Version="19.4.0.53" />

    <PackageReference Include="Syncfusion.Xamarin.Presentation" Version="19.4.0.53" />

    <PackageReference Include="Syncfusion.Xamarin.SfChart" Version="19.4.0.53" />

    <PackageReference Include="Syncfusion.Xamarin.SfListView" Version="19.4.0.53" />

    <PackageReference Include="Syncfusion.Xamarin.SfPopupLayout" Version="19.4.0.53" />

Here is the code snippet:

                        <syncfusion:SfListView AllowKeyboardNavigation="True" x:Name="lstProjectValueMetrics" WidthRequest="200"  HeightRequest="200">

<syncfusion:SfListView.RowDefinitions>
<RowDefinition Height="*"/>
</syncfusion:SfListView.RowDefinitions>
                            <syncfusion:SfListView.ItemTemplate>
                                    <DataTemplate>
                                        <ViewCell>
                                            <StackLayout Orientation="Horizontal" HorizontalOptions="Start">
                                                <StackLayout Padding="5" Orientation="Vertical" VerticalOptions="Start">
                                                    <Label  Style="{StaticResource DefaultLabelSmallBoldStyle}" Text="{Binding DisplayName}"/>
                                                    <Label  Style="{StaticResource DefaultLabelSmallStyle}" FontAttributes="Italic" Text="{Binding DisplayValue}"/>
                                                <!-- <Label  Style="{StaticResource DefaultLabelSmallStyle}" FontAttributes="Italic" Text="{Binding MetricValue, StringFormat='{0:0,0.00}'}"/> -->
                                            </StackLayout>
                                            </StackLayout>
                                        </ViewCell>
                                    </DataTemplate>
                                </syncfusion:SfListView.ItemTemplate>
                            </syncfusion:SfListView>

It does not work both on UWP as well as in Android
