How show first tab

[rafleboss47]

Hello,

I've just implemented tabs in my project.
How do I pre-select the first TAB?
By default, no tabs are selected.

I use the following system:

`<tabs:TabHostView x:Name="TabHost"
Grid.Row="1"
Margin="0"
BackgroundColor="Black"
SelectedIndex="{Binding Source={x:Reference Switcher}, Path=SelectedIndex, Mode=TwoWay}"
TabType="Fixed"
>
<tabs:TabHostView.Tabs >
<tabs:UnderlinedTabItem IsSelected="True" IsSelectable="True" x:Name="onglet1" Label="MMM" SelectedTabColor="White" UnselectedLabelColor="Gray"/>
<tabs:UnderlinedTabItem Label="YYYY" SelectedTabColor="White" UnselectedLabelColor="Gray"/>
</tabs:TabHostView.Tabs>
</tabs:TabHostView>

<ScrollView Grid.Row="2">
    <tabs:ViewSwitcher x:Name="Switcher"
                       Animate="True"                           
                       SelectedIndex="{Binding SelectedViewModelIndex, Mode=TwoWay}"
                       TabIndex="1"
                       >
               <StackLayout  Margin="0" Padding="0" BackgroundColor="White" Spacing="0">
                <Label TextColor="Black" Margin="0"  Padding="10,0,10,0" Text="RENDEZ-VOUS PASSES" FontSize="Large" VerticalOptions="CenterAndExpand" HorizontalOptions="Center"></Label>
                <StackLayout  HeightRequest="6" BackgroundColor="Black"  Margin="0"></StackLayout>
            </StackLayout>

</tabs:Shadows>

Set the SelectedViewModelIndex to the index you want
