I have a Xamarin.Forms SearchBar to search for information on a remote server. This data is displayed in a ListView below the searchbar like the following:
Pseudocode:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage ... >
<ContentPage.Content>
<StackLayout>
<SearchBar
x:Name="SearchBar"
Placeholder="Search for a business..."
HorizontalTextAlignment="Start"
SearchCommand="{Binding PerformSearch}"
SearchCommandParameter="{Binding Text, Source={x:Reference SearchBar}}">
</SearchBar>
<ListView
x:Name="SearchResults"
ItemsSource="{Binding Path=SearchResults}"
...
>
</ListView>
</StackLayout>
</ContentPage.Content>
</ContentPage>
Is it possible to disable the autocomplete/autocorrect in the keyboard? I know for a Text.Entry it is possible to set IsTextPredictionEnabled to false but I don't see a way to configure a SearchBar in a similar way.
Yes, according to the SearchBar Properties, the Keyboard for the InputView is exposed. Therefore, similar to this answer, it can be achieved in the XAML by using the x:FactoryMethod attribute:
<SearchBar
x:Name="SearchBar"
Placeholder="Search for a business..."
HorizontalTextAlignment="Start"
SearchCommand="{Binding PerformSearch}"
SearchCommandParameter="{Binding Text, Source={x:Reference SearchBar}}">
<SearchBar.Keyboard>
<Keyboard x:FactoryMethod="Create">
<x:Arguments>
<KeyboardFlags>None</KeyboardFlags>
</x:Arguments>
</Keyboard>
</SearchBar.Keyboard>
</SearchBar>

I make a customize title in the titleview,
and I want to show different content(with other pages) by pressing the tabs I customize.(like pic shows below)
I am wondering how to change the content with different pages...
<ContentPage>
<NavigationPage.TitleView>
<Button x:Name="energy" />
<Button x:Name="history" />
...
</NavigationPage.TitleView>
<ContentPage.Content>
//when I press energy, and content shows the Energy.xaml
//when I press history, and content shows the History.xaml
</ContentPage.Content>
</ContentPage>
You can use TabView from XamarinCommunityToolkit package, here is a sample page you can find it in their sample repo.
<ContentPage xmlns:xct="http://xamarin.com/schemas/2020/toolkit"
...
>
<ContentPage.Content>
<Grid>
<xct:TabView
TabStripBackgroundColor="Blue"
TabStripHeight="40"
TabIndicatorColor="Yellow"
TabContentBackgroundColor="Yellow">
<xct:TabViewItem
Text="Tab 1"
TextColor="White"
TextColorSelected="Yellow"
FontSize="12">
<--Here you define the content of Tab1 -->
</xct:TabViewItem>
<xct:TabViewItem
Text="Tab 2"
TextColor="White"
TextColorSelected="Yellow"
FontSize="12">
<--Here you define the content of Tab2 : it can be the ContentView defined in your Energy.xaml -->
</xct:TabViewItem>
</xct:TabView>
</Grid>
<ContentPage.Content>
</ContentPage>
There is plenty of stuff you can customize take a look at the official documentation.
I am trying to achieve the effect, cross-platform(ios, android and uwp), as shown in the image below:
Clicking "More" normally would open a page, as normal behaviour for a tab bar item. Not sure how to override that behaviour and reveal the sliding master page instead. To the left of the "More" tab bar item, theres another tab bar item, when clicked it refreshes the data on (or reloads) the MainPage.
SettingsPage.xaml (master page, the sliding settings page)
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:MyProject.Classes"

<!-- second link should be the sandwhich button that brings up the settings page -->
</TabbedPage.Children>
</TabbedPage>
MainPage.xaml (the main page, navigated to by the left TabBar link icon, to the left of the sandwhich icon with title "More")
<ContentPage.Content>
<StackLayout>
<Label Text="Welcome to the Main page!"
VerticalOptions="CenterAndExpand"
HorizontalOptions="CenterAndExpand" />
</StackLayout>
</ContentPage.Content>
An easy way I can achieve the effect is to use Shell. It's released for months and just check your VS version for the correct template.
Create a new Xamarin.Forms project using VS2019.
You can use Shell out of the box if you can see the following screen.
Find "ItemsPage.xaml" in the Views folder.
Add one line in the ContentPage at the top
<ContentPage
...
Shell.TabBarIsVisible="False">
Add a StackLayout to contain the existing CollectionView and add your bottom buttons.
<RefreshView ...>
<!-- new StackLayout -->
<StackLayout>
<CollectionView ..... />
<!-- new Buttons -->
<StackLayout
HeightRequest="52"
Orientation="Horizontal"
BackgroundColor="#2196F3"
Visual="Material">
<Button
WidthRequest="200"
BackgroundColor="Transparent"
Text="Refresh"
Command="{Binding LoadItemsCommand}" />
<Button
BackgroundColor="Transparent"
Text="More"
Clicked="Button_Clicked" />
</StackLayout>
</StackLayout>
Go to "ItemsPage.xaml.cs" to complete the button event, add a method:
private void Button_Clicked(object sender, EventArgs e)
{
Shell.Current.FlyoutIsPresented = true;
}
Set startup project and deploy, check the effect and play around.
Additionally, in the latest Xamarin.Forms, UWP Shell is an experimental feature, and so does in XF 5.0. But the flyout things will probably work fine (not too sure about this).
An alternative, following the idea from #Shaw, but without Shell is to use the good old MasterDetail Page (which supports UWP) and add two buttons at the bottom to provide the "More" and "Refresh" functionality.
If this sounds like a good option for you, keep reading:
Add a Master-Detail Page to your Solution
On Visual Studio 2019 adding a Master-Detail to your solution is pretty straight forward. You only need to right click the Xamarin.Forms Project in the Solution Explorer and go to Add -> New Item (or simply use the shortcut Ctrl+Shift+A):
in the window that appears, select Master-Detail Page, give it a cool name (MasterDetailPage1 in this example!) and click Add:
By doing this you successfully have added a Master Detail to your solution. Now just go to App and set MainPage to it as follows:
MainPage = new MasterDetailPage1();
Add the bottom buttons
Now we want two buttons at the bottom of our Detail page. This is simply done by adding a stack of two buttons that locate at the end. Our newly added MasterDetailPage1Detail.xaml will then look like:
<?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="MasterTabRefresh.MasterDetailPage1Detail"
Title="Detail">
<StackLayout>
<Label Text="This is a detail page. To get the 'triple' line icon on each platform add a icon to each platform and update the 'Master' page with an Icon that references it."
Padding="10"/>
<StackLayout Orientation="Horizontal"
VerticalOptions="EndAndExpand"
Spacing="0">
<Button BackgroundColor="CornflowerBlue"
Text="Refresh"
TextColor="White"
CornerRadius="0"
HorizontalOptions="FillAndExpand"/>
<Button BackgroundColor="CornflowerBlue"
Text="More"
TextColor="White"
CornerRadius="0"
HorizontalOptions="FillAndExpand"
Clicked="MoreClicked"/>
</StackLayout>
</StackLayout>
</ContentPage>
which should look like:
And in the code behind (MasterDetailPage1Detail.xaml.cs ) we add the "More" functionality:
private void MoreClicked(object sender, EventArgs e)
{
((MasterDetailPage)Application.Current.MainPage).IsPresented = !((MasterDetailPage)Application.Current.MainPage).IsPresented;
}
Add a nice X (close) button to your menu/master
This could be achieved by adding a label with an "X" at the top right of the menu.
Simply modify your MasterDetailPage1Master.xaml to look like (note Label at Column 2 Row 0!)
<?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="MasterTabRefresh.MasterDetailPage1Master"
Title="Master">
<StackLayout>
<ListView x:Name="MenuItemsListView"
SeparatorVisibility="None"
HasUnevenRows="true"
ItemsSource="{Binding MenuItems}">
<ListView.Header>
<Grid BackgroundColor="#03A9F4">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="30"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition Height="80"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="10"/>
</Grid.RowDefinitions>
<Label Grid.Column="2"
Grid.Row="0"
Text="X"
FontAttributes="Bold"
HorizontalTextAlignment="Center"
VerticalTextAlignment="Center">
<Label.GestureRecognizers>
<TapGestureRecognizer Tapped="X_Tapped"/>
</Label.GestureRecognizers>
</Label>
<Label
Grid.Column="1"
Grid.Row="2"
Text="My wonderful App"
Style="{DynamicResource SubtitleStyle}"/>
</Grid>
</ListView.Header>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Padding="15,10" HorizontalOptions="FillAndExpand">
<Label VerticalOptions="FillAndExpand"
VerticalTextAlignment="Center"
Text="{Binding Title}"
FontSize="24"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</ContentPage>
Which should look like this:
And then add the "Close" functionality to that "X" Label in the code behind (MasterDetailPage1Master.xaml):
private void X_Tapped(object sender, EventArgs e)
{
((MasterDetailPage)Application.Current.MainPage).IsPresented = false;
}
And that is it! This should get you going. Happy coding!
Can I create a view including Entry Progress bar or others to make a view which I can use in other places?
for example I want to create a card view which I can use to list the lists.
I can only write in the list not to write the card in every list.
Yes, you can create a custom view and use it in the MainPage or other Pages, Views you want.
To create a custom view, add a new item --> ContentView,let's call it CardView:
In .cs of CardView:
public partial class CardView : ContentView
{
public CardView()
{
InitializeComponent();
}
}
In xaml of CardView, add your labels,progressbar, entry there:
<?xml version="1.0" encoding="UTF-8"?>
<ContentView 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"
mc:Ignorable="d"
x:Class="App35.CardView">
<ContentView.Content>
<StackLayout>
<Label Text="Hello Xamarin.Forms!" />
<ProgressBar Progress="0.5" />
<Entry Placeholder="I'm entry"/>
</StackLayout>
</ContentView.Content>
</ContentView>
To use it in MainPage, in listView or in the page:
<StackLayout>
<projectName:CardView HorizontalOptions="Center" VerticalOptions="CenterAndExpand" />
<ListView x:Name="listView" RowHeight="70">
<ListView.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>mono</x:String>
<x:String>monodroid</x:String>
</x:Array>
</ListView.ItemsSource>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<projectName:CardView HorizontalOptions="Center" VerticalOptions="CenterAndExpand" />
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
I upload a sample here and you can check.
Yes you can do that using ContentView, if you want to use it as views
Or you can make ViewCells if you want to use it in ListViews. Its easy and almost every project does that.
You can refer this link :- https://xamarinhelp.com/xamarin-forms-user-control/
Let me know if you have more questions on this. Thanks!
In Xamarin Forms 4.1, When scroll, scrollview content is covering/overflow the headerview and scrollview content is not shown completely.
Tried with IsClippedToBounds to true.
Created scrollviewrenderer, OnDraw() -> set clip to bound property. But didn't worked.
Example: Here is the XAML design
<Stacklayout>
<HeaderView/>
<ScrollView IsClippedToBounds="true">
<Stacklayout>
<label text="1"/>
........
........
<label text="100"/>
</Stacklayout>
</ScrollView>
</Stacklayout>
I make a custom control as the headerview in your description. And test on Xamarin.forms 4.1, works well.
MyCustomConrol:
<StackLayout Orientation="Horizontal" BackgroundColor="Aqua">
<Label x:Name="Title_label" Text="Title" TextColor="Black" FontSize="25" HorizontalOptions="StartAndExpand" Margin="8,0,4,0"/>
<Button x:Name="btnHello" Text="Hello" HorizontalOptions="EndAndExpand" Margin="4,0,8,0"/>
</StackLayout>
MainPage.xaml
<StackLayout>
<local:MyCustomControl></local:MyCustomControl>
<!--<HeaderView/>-->
<ScrollView IsClippedToBounds="true">
<StackLayout>
<Label Text="1"/>
<Label Text="2"/>
<Label Text="3"/>
……………
…………………
</StackLayout>
</ScrollView>
Result:
You could download from ScrollView/XamarinDemo folder of GitHub for reference.

If you want your header to be always visible then rather than placinf your content in Header, it will be better to place your header content first then below that place your listview. Thus, your header remains intact and listview scrolls.
Is it possible to add a switch on the toolbar?
<ContentPage.ToolbarItems>
<ToolbarItem>
<Switch x:Name="Switch1" IsToggled="True" Margin="5,0,0,0"/>
</ToolbarItem>
</ContentPage.ToolbarItems>
Does anybody have any ideas?
Thanks!
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:TitleViewSample"
x:Class="TitleViewSample.MainPage">
<NavigationPage.TitleView>
<Switch x:Name="Switch1" IsToggled="True" Margin="5,0,0,0"/>
</NavigationPage.TitleView>
<ContentPage.Content>
<StackLayout>
<!-- Place new controls here -->
<Label Text="Welcome to Xamarin.Forms!"
HorizontalOptions="Center"
VerticalOptions="CenterAndExpand" />
</StackLayout>
</ContentPage.Content>
</ContentPage>
I don't think it is possible. You can, however, take the same approach I did when I needed to customise my title bar.
First, you hide the navigation bar, then you can specify your bar at the top, and use the controls you would like.
