SfTabview with 3 or more tabs leading to unhandled exception on UWP

[Peter]

Hello,

in my application Im using SfTabView with 3 tabs. On Android and IOS it works fine, but on UWP, when i tap "About" (second time) from navigaton drawer, problem appears. 

My AboutPage with 3 tabs: 

<?xml version="1.0" encoding="utf-8" ?>

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

             xmlns:d="http://xamarin.com/schemas/2014/forms/design"

             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

             xmlns:tabView="clr-namespace:Syncfusion.XForms.TabView;assembly=Syncfusion.SfTabView.XForms"

             mc:Ignorable="d"

             x:Class="tst.Views.AboutPage"

             xmlns:vm="clr-namespace:tst.ViewModels"

             Title="{Binding Title}">

    

    <ContentPage.BindingContext>

        <vm:AboutViewModel />

    </ContentPage.BindingContext>

    <ContentPage.Content>

        <tabView:SfTabView BackgroundColor="Aqua">

            <tabView:SfTabItem Title="Call">

                <tabView:SfTabItem.Content>

                    <Grid BackgroundColor="Red" x:Name="AllContactsGrid" />

                </tabView:SfTabItem.Content>

            </tabView:SfTabItem>

            <tabView:SfTabItem Title="Favorites">

                <tabView:SfTabItem.Content>

                    <Grid BackgroundColor="Green" x:Name="FavoritesGrid" />

                </tabView:SfTabItem.Content>

            </tabView:SfTabItem>

            <tabView:SfTabItem Title="Contacts">

                <tabView:SfTabItem.Content>

                    <Grid BackgroundColor="Blue" x:Name="ContactsGrid" />

                </tabView:SfTabItem.Content>

            </tabView:SfTabItem>

        </tabView:SfTabView>

    </ContentPage.Content>

</ContentPage>

To reprodut issue I: 

1. launch app

2. click to "About"

3. Click to "Browse"

4. Click to "About" (problem appears) 

When I remove one tab from AboutPage.xaml, then everithing works fine. 

Thank you in advance

Hi Sakthivel,

when I click on "Browse" in your UWP app, navigation drawer disappears so I'm unable to test problematic scenario (problem was when navigating back and forth in navigation drawer).

Thanks 

Peter
