Hi,
I have a MasterDetailPage like this
<?xml version="1.0" encoding="utf-8" ?>
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:views="clr-namespace:Fake.Views"
xmlns:prism="clr-namespace:Prism.Mvvm;assembly=Prism.Forms"
prism:ViewModelLocator.AutowireViewModel="True"
MasterBehavior="Popover"
Icon="hamburger" x:Class="Fake.Views.MainView">
<MasterDetailPage.Master>
<views:MenuView BindingContext="{Binding MenuViewModel}" />
</MasterDetailPage.Master>
<MasterDetailPage.Detail>
<views:NavigationPage >
<x:Arguments>
<views:ContentTabbedPageView BindingContext="{Binding ContentTabbedPageViewModel}" />
</x:Arguments>
</views:NavigationPage>
</MasterDetailPage.Detail>
</MasterDetailPage>
And the ContentTabbedPageView is:
<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:prism="clr-namespace:Prism.Mvvm;assembly=Prism.Forms"
xmlns:views="clr-namespace:Fake.Views"
xmlns:extensions="clr-namespace:Fake.Core.MarkupExtensions;assembly=Fake"
prism:ViewModelLocator.AutowireViewModel="True"
x:Class="Fake.Views.ContentTabbedPageView"
BarBackgroundColor="{StaticResource BackgroundColor}"
BarTextColor="{StaticResource BlackColor}"
BackgroundColor="{StaticResource BackgroundColor}" >
<TabbedPage.ToolbarItems>
<ToolbarItem
Command="{Binding OpenDoorCommand}">
<ToolbarItem.Icon>
<OnPlatform x:TypeArguments="FileImageSource">
<On Platform="Android, iOS" Value="search" />
</OnPlatform>
</ToolbarItem.Icon>
</ToolbarItem>
</TabbedPage.ToolbarItems>
<TabbedPage.Children>
<NavigationPage Title="{extensions:Translate Chat, IsUpper=True}" >
<x:Arguments>
<views:ChatView />
</x:Arguments>
</NavigationPage>
<NavigationPage Title="{extensions:Translate Social, IsUpper=True}" >
<x:Arguments>
<views:SocialView />
</x:Arguments>
</NavigationPage>
<NavigationPage Title="{extensions:Translate Cash, IsUpper=True}" >
<x:Arguments>
<views:CashView />
</x:Arguments>
</NavigationPage>
</TabbedPage.Children>
</TabbedPage>
Now I'd like from the SocialView to open a modal page with a navigation bar. The SocialView is:
<?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:prism="clr-namespace:Prism.Mvvm;assembly=Prism.Forms"
xmlns:controls="clr-namespace:ImageCircle.Forms.Plugin.Abstractions;assembly=ImageCircle.Forms.Plugin.Abstractions"
xmlns:ctrls="clr-namespace:Fake.Core.Controls;assembly=Fake"
xmlns:markupExtensions="clr-namespace:Fake.Core.MarkupExtensions;assembly=Fake"
prism:ViewModelLocator.AutowireViewModel="True"
x:Class="Genuiny.Views.SocialView" Title="Social">
<ContentPage.Resources>
<ResourceDictionary>
<Style x:Key="TooltipTextStyle"
TargetType="Label"
BasedOn="{StaticResource TooltipLabelStyle}">
<Setter Property="TextColor"
Value="{StaticResource BlackColor}" />
<Setter Property="HorizontalOptions"
Value="FillAndExpand" />
<Setter Property="FontSize"
Value="{StaticResource LittleSize}" />
</Style>
</ResourceDictionary>
</ContentPage.Resources>
<Grid BackgroundColor="{StaticResource BackgroundColor}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="20"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="50" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Grid.Column="1" Margin="0,20,0,10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="42" />
</Grid.RowDefinitions>
<Image Source="add.png" WidthRequest="32" Margin="10,0,0,0" x:Name="addPostButton">
<Image.GestureRecognizers>
<TapGestureRecognizer Command="{Binding BindingContext.AddPostCommand, Source={x:Reference addPostButton}}" />
</Image.GestureRecognizers>
</Image>
<ctrls:RoundedEntry Margin="0,0,0,0" Grid.Column="1" BorderColor="{StaticResource GrayColor}" BorderWidth="0.5" BorderRadius="20"
Style="{StaticResource TooltipLabelEntryStyle}"
Placeholder="{markupExtensions:Translate Share, IsUpper=True}" HorizontalOptions="FillAndExpand">
</ctrls:RoundedEntry>
</Grid>
</Grid>
</ContentPage>
On the ViewModel, in the AddPostCommand I do this:
await _navigationService.NavigateAsync("AddPostView", useModalNavigation:true);
The expected behaviours is to view the new page with a navigation bar, but the new page appears without a navigation bar and if i don't use modalnavigation the page appears inside the current tab.
What am i wrong? Thanks for any kind of help.
I'm using:
Prism 7.1.0.123 pre
Xamarin.Forms 3.0 pre2
