What kind of control is this? - maui

I've noticed many apps have settings pages which have controls which behave like buttons, but don't look like buttons.
Anyone know what type of controls these are?
Specifically the one I am tapping on in the linked video file below:
Video example.

It's not a regular control but to do this in Maui you can use the Popup control to replicate a behaviour which is similar to what you just showed
Create a popup as shown here :
<toolkit:Popup xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"
x:Class="MyProject.SimplePopup">
<VerticalStackLayout>
<Label Text="This is a very important message!" />
</VerticalStackLayout>
</toolkit:Popup>
Its cs file :
public partial class SimplePopup : Popup
{
public SimplePopup()
{
InitializeComponent();
}
}
And then use Radiobuttons from Maui to achieve the UI you need.
And for that effect use touch effects Its being ported to Maui at the moment though As far as I know (Not sure if works as a compatibility package)
I hope this helps!

It's a picker control, you can get more info here: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/picker
<StackLayout>
<Label Text="Theme"
Margin="0,25,0,5"
FontAttributes="Bold"/>
<Picker x:Name="picker"
Title="Select theme">
<Picker.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>Light</x:String>
<x:String>Dark</x:String>
<x:String>Black</x:String>
<x:String>Automatic (device theme)</x:String>
</x:Array>
</Picker.ItemsSource>
</Picker>

Syncfusion MAUI DataGrid and VerticalStackLayout

I would like to add label above Syncfusion Datagrid but the label is hidden when I run the app in the following page.
See the following repos for complete app.
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="DataGrid.Views.OrderInfoRepositoryView"
xmlns:syncfusion="clr-namespace:Syncfusion.Maui.DataGrid;assembly=Syncfusion.Maui.DataGrid"
xmlns:local="clr-namespace:DataGrid"
Title="Order Info Repository View">
<ContentPage.BindingContext>
<local:OrderInfoRepositoryViewModel x:Name="viewModel" />
</ContentPage.BindingContext>
<ContentPage.Content>
<VerticalStackLayout Margin="20"
Spacing="10">
<Label Text="OrderInfo"
Margin="10,10,10,10"
TextColor="White"
BackgroundColor="Red"/>
<syncfusion:SfDataGrid x:Name="dataGrid"
ItemsSource="{Binding OrderInfoCollection}">
</syncfusion:SfDataGrid>
</VerticalStackLayout>
</ContentPage.Content>
Did try the following but same result.
<Label Text="OrderInfo"
Margin="10,10,10,10"
TextColor="White"
BackgroundColor="Red"/>
<syncfusion:SfDataGrid x:Name="dataGrid"
ItemsSource="{Binding OrderInfoCollection}">
</syncfusion:SfDataGrid>
</VerticalStackLayout>
Here Android screenshot
Added LineHeight and fontSize. No change
Tested with HeightRequest. No change.
It appears that you have set the Content for the ContentPage as DataGrid in OrderInfoRepositoryView.xaml.cs file. Please refer to the below file,
https://github.com/JeanMarcFlamand/MauiSyncFusionExamples/blob/master/DataGrid/Views/OrderInfoRepositoryView.xaml.cs#L12
You are adding the DataGrid as the content of the page in code behind i.e., OrderInfoRepositoryView constructor. That’s why the DataGrid alone is displaying without Label. We request that you remove the codes inside the OrderInfoRepositoryView constructor to overcome the issue.

How to implement custom icon in SAPUI5's Shellbar Control?

I implemented a functionality so that the users of my SAPUI5 application can change between different SAPUI5 themes. Now I would like to place a button in the existing ShellBar of my app to trigger that functionality from there.
Currently I have a fragment with the following code, which I want to make use of within a simple button in the ShellBar. I tried different things like f.ex. calling it via the avaterPressed attribute from the shellbar, but it looks all messed up - I'd be very happy if someone could help me out here - Thanks!
<core:FragmentDefinition
xmlns="sap.m"
xmlns:core="sap.ui.core">
<Menu itemSelected="onSelectTheme" >
<MenuItem text="Choose Theme">
<items>
<MenuItem key="sap_fiori_3" text="Standard Light" />
<MenuItem key="sap_fiori_3_dark" text="Standard Dark" />
<MenuItem key="sap_hcw" text="High Contrast White" />
<MenuItem key="sap_hcb" text="High Contrast Black" />
</items>
</MenuItem>
</Menu>
</core:FragmentDefinition>
It should look like the "Administrator" button in the following example (Instead of "User Settings" there should be my text "Choose Theme" from the fragment shown above: https://sapui5.hana.ondemand.com/sdk/test-resources/sap/tnt/demokit/toolpageapp/webapp/index.html?sap-ui-theme=sap_horizon#/
If you want to keep using the ShellBar, you can implement the press event on the Avatar and use the ActionSheet for your needs.
https://sapui5.hana.ondemand.com/#/entity/sap.m.ActionSheet/sample/sap.m.sample.ActionSheet
The developers from the linked example don't use the SAPUI5 Control ShellBar, but instead they made use of ToolHeader, which you can also implement within the Control ToolPage.
With ToolHeader, you can simply add a Button wherever you'd like and also call the fragment from f.ex. the profile picture button (shown below).
<tnt:ToolHeader>
<Avatar src="..." press="YOUR_FUNCTION_TO_OPEN_FRAGMENT"/>
</tnt:ToolHeader>

Add Transparent Background Color to Popup Page for MAUI using Community Toolkit in iOS

I started working with .NET MAUI.
Installed Community Toolkit to display Popup.
Popup UI doesn't show transparent background color in iOS where as in Android it works perfectly fine.
Android:
iOS:
Added XAML File for Popup:
Popup:
<?xml version="1.0" encoding="utf-8" ?>
<mct:Popup
xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="testpopup.PopupPage"
xmlns:mct="clr-namespace:CommunityToolkit.Maui.Views;assembly=CommunityToolkit.Maui"
>
<VerticalStackLayout BackgroundColor="Transparent">
<Label
Text="Welcome to .NET MAUI!"
VerticalOptions="Center"
HorizontalOptions="Center" />
</VerticalStackLayout>
</mct:Popup>
I just modified the button on MainPage to display the popup:
private void OnCounterClicked(object sender, EventArgs e)
{
this.ShowPopup(new PopupPage());
}
Any help is appreciated!
This issue has been resolved in latest version of CommunityToolkit.Maui 4.0.0
There is the same problem in GitHub issue, and as the answerer said, this is normal behavior for iOS. In iOS, the hierarchy is managed by the view controller. Each page has a separate view controller. A page consists of a window, a root view, and a subview. You cannot see the layout of the previous page by setting the background color to be transparent.
For more details, you can refer to the following documents:
User interface | Microsoft
The View Controller Hierarchy | Apple

Why Prism's Master Detail Page structure is different from Xamarin.Forms?

I developed one app about months ago with Prism. It's great tool that make perfect structure for my app.
However, today I tried to pick up that app and fix some things that pending for a long time. I used Master Detail page in my app, and today I suddenly found that actually the structure for how I developed this Master Detail page using Prism is kind of out of my knowledge.
So, here it is.
Basically my MasterDetailPage is 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:d="http://xamarin.com/schemas/2014/forms/design"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:b="clr-namespace:Prism.Behaviors;assembly=Prism.Forms"
mc:Ignorable="d"
x:Class="JapaneseLearnPrism.Views.MenuPage">
<MasterDetailPage.Master>
<NavigationPage Title="Menu" Icon="ic_hamburger.png">
<x:Arguments>
<ContentPage Title="{Binding Title}">
<ListView ItemsSource="{Binding MenuItems}"
SelectedItem="{Binding SelectedMenuItem, Mode=TwoWay}"
SeparatorColor="LightGray"
RowHeight="60"
SeparatorVisibility="Default"
BackgroundColor="#e8e8e8">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout VerticalOptions="FillAndExpand"
Orientation="Horizontal"
Padding="20,10,0,10"
Spacing="20">
<Label Text="{Binding PageIconText}" FontFamily="{StaticResource FontAwesomeSolid}" FontSize="Medium" VerticalOptions="Center" />
<Label Text="{Binding Title}" FontSize="Medium" VerticalOptions="Center" TextColor="Black" />
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.Behaviors>
<b:EventToCommandBehavior EventName="ItemTapped" Command="{Binding NavigateCommand}" />
</ListView.Behaviors>
</ListView>
</ContentPage>
</x:Arguments>
</NavigationPage>
</MasterDetailPage.Master>
</MasterDetailPage>
And the navigation path is this in App.xaml.cs file.
await NavigationService.NavigateAsync(nameof(MenuPage) + "/" + nameof(NavigationPage) + "/" + nameof(Views.MainPage));
But if I look at lots of the Xamarin.Forms samples, the MasterDetailPage is actually different.
They are going to do like below:
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:MasterDetailPageNavigation;assembly=MasterDetailPageNavigation"
x:Class="MasterDetailPageNavigation.MainPage">
<MasterDetailPage.Master>
<local:MasterPage x:Name="masterPage" />
</MasterDetailPage.Master>
<MasterDetailPage.Detail>
<NavigationPage>
<x:Arguments>
<local:ContactsPage />
</x:Arguments>
</NavigationPage>
</MasterDetailPage.Detail>
</MasterDetailPage>
And that's from Microsoft's official website. The Master Page in above is actually just one ContentPage, however, the Detail page should be NavigationPage, that one I can understand because it makes sense.
However, in my Prism app, the MasterPage also has to be a NavigaionPage, why is that? Any one can help on this?
Thanks.
You can take a look at this wonderfull blog about How to make Master-Detail Page Navigation menu in Xamarin Forms with Prism.
If you scroll down to the bottom of the post, you will see some description on why it works this way, Quoting:
Note: Navigation in Prism is all based on this url format where we can define to which pages we want to go, and it can be something like this: ViewA/ViewB/ViewC/ViewD
... and if you remember we are inside of MasterDetail page so navigating from MasterDetail will get result that those pages will go to Detail part of it... and that is great for us, we have menu in side of master page and choosing menu items will open pages as Detail pages.
The way that Prism Navigation is designed, it makes sense that a DetaiPage goes inside the MasterDetail, so basically it keeps the Prism Logic of doing the Navigation.
Quoting the Basics of Prism Navigation
Navigating in a Prism application is conceptually different than standard navigation in Xamarin.Forms. While Xamarin.Forms navigation relies on a Page class instance to navigate, Prism removes all dependencies on Page types to achieve loosely coupled navigation from within a ViewModel. In Prism, the concept of navigating to a View or navigating to a ViewModel does not exist. Instead, you simply navigate to an experience, or a unique identifier, which represents the target view you wish to navigate to in your application.

Prevent sap.m.popover from closing on click

How do I prevent sap.m.popover from closing when the user clicks somewhere else on the page? Is there any solution to this requirement? I was not able to finde anything regarding this in the documentation.
Can someone point me in the right direction, please?
Isnt the property modal what you are looking for?
The popover will not be closed when tapping outside the popover. It also blocks any interaction with the background. The default value is false.
Check the demo kit for the modal property. The Demo-kit is really something you should often use, it could help you a lot.
<Popover title="Test" class="sapUiContentPadding" placement="Bottom" modal="true">
//whatever you want inside your popover
<footer>
<Toolbar>
<ToolbarSpacer/>
<Button
id="close"
text="Close"
press="handlClosePress" />
</Toolbar>
</footer>
</Popover>
