I'm working on Xamarin Project and I don't need navigation bur, I switched it off but now I cant move app content of page
<?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="http://prismlibrary.com"
prism:ViewModelLocator.AutowireViewModel="True"
xmlns:imgExt="clr-namespace:GulfStar.Xamarin.Extensions"
x:Class="GulfStar.Xamarin.Views.StatusPickerPage"
NavigationPage.HasNavigationBar="False">
<StackLayout>
<StackLayout Orientation="Horizontal" VerticalOptions="Start" >
<Image Source="{imgExt:ImageResource GulfStar.Xamarin.Images.Icon.png}" WidthRequest="70" HeightRequest="70"/>
<Label HorizontalOptions="Center" Margin="0,17,0,0" FontSize="Title">GSI Accountability</Label>
</StackLayout>
</StackLayout>
</ContentPage>
I figured out who it happen
How to remove blue section
Use NavigationPage.SetHasNavigationBar(this, false); to hide the navigation bar.
I figured out how to make that thing disappears
when you navigation to some page does not use Navigation page NavigationService.NavigateAsync("NavigationPage/StatusPickerPage");
Use
NavigationService.NavigateAsync("StatusPickerPage");
And it would not track navigation and its not needed if you have only two pages

In one xaml file I have a carousel. Starting from the second section, the code for the next page is also listed here. For compactness I would like to make as partial applications in asp.net. Is it possible to split the Contentpage into different files for each page for greater convenience? Thanks !
<CarouselPage 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">
<ContentPage
BackgroundImage="background">
<ContentPage.Content>
<StackLayout>
<Image
Source="logo">
</Image>
<Frame>
<local:SearchProfile
Keyboard="Default">
</local:SearchProfile>
</Frame>
<Image
Source="starttext">
</Image>
</StackLayout>

You can’t have multiple pages in one page. You can only have multiple layouts inside a page.
The CarouselPage can’t have a ContentPage inside it and vice versa. However the CarouselPage can have multiple layouts in it (Stack, Relative, Absolute, Frame, Grid)
Here's a quick snippet explaining Pages vs Layouts.
The font that I have is too big for the amount of words that I would like to display. Does anyone have any suggestions as to how I can change the font size. I would prefer to be able to do it in the shared code but if it needs a custom renderer then can someone show me how this can be done?
So, if you are using Xamarin.Forms 3.2.0 or above, you can use TitleView property like this:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Xamarin.Forms.Controls.GalleryPages.TitleView">
<NavigationPage.TitleView>
<Label Text="This is my Title" FontSize="12" TextColor="White" />
</NavigationPage.TitleView>
<!-- YOUR CONTENT HERE-->
</ContentPage>
In my xamarin app,I want to add a search bar on top of the page in my tabbed page.
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Sample.Mobile.Test">
<StackLayout>
<SearchBar></SearchBar>
</StackLayout>
<TabbedPage.Children>
<ContentPage x:Name="tab1" Title="Home">
</ContentPage>
</TabbedPage.Children>
</TabbedPage>
You can use follow this link for the Search bar Implementation

I am working on an application where the developer has a <ContentPage> with a <TableView> inside. Is this needed / normal practice? I am trying to work out why the developer did this.
The developer added a element surrounding the <TableView>
<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
Title="Network">
<ContentPage.Content>
<StackLayout>
<TableView>
...
</TableView>
</StackLayout>
</ContentPage.Content>
</ContentPage>
A ContentPage can only have a single child element. It's not uncommon to include some sort of Layout container as the child, so multiple child elements can be added to the page. However, in cases like this where there is really only a single child it's probably unnecessary.
I've inherited a Xamarin project and am not sure why I'm seeing this behavior when trying to work with a CarouselPage.
Using the Prism NavigationService, if I navigate to the carousel page as the "base page", it shows fine, but if I navigate to it as a "sub page" (to push it on the navigation stack?) it doesn't show, though I get no errors.
The problem is that using the navigation method that works doesn't provide me with a back button.
Example:
// this works, but no back button
await _navigationService.NavigateAsync("file:///MenuMasterDetailPage/MenuNavigationPage/MyCarouselPage");
// this doesn't, have back button but no content is shown
await _navigationService.NavigateAsync("MyCarouselPage");
I'm unsure how the master/detail/navigation stuff really works: not sure if my issue is there or if there's something special about a CarouselPage that prevents it from being rendered in the second case.
The MyCarouselPage is as simple as can be while I try to get this to work:
<?xml version="1.0" encoding="utf-8" ?>
<CarouselPage 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"
x:Class="Views.ImageCarouselPage"
effects:BackgroundImageEffect.BackgroundImage="Resources.SignInBackground.png">
<ContentPage>
<StackLayout VerticalOptions="FillAndExpand">
<Image Source="https://s3.amazonaws.com/blah.jpg" Aspect="AspectFit" VerticalOptions="FillAndExpand" />
</StackLayout>
</ContentPage>
<ContentPage>
<StackLayout VerticalOptions="FillAndExpand">
<Image Source="https://s3.amazonaws.com/blah.jpg" Aspect="AspectFit" VerticalOptions="FillAndExpand" />
</StackLayout>
</ContentPage>
</CarouselPage>
(I should note that the background image does display, but the contents of the carousel does not).
Any ideas? Thanks.
