The main goal of the task to create AutoSuggest control.
In my case AutoSuggest control is custom control inherited from Grid
<Grid xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
...
xmlns:handlers ="clr-namespace:CrowdExchangeV2.Controls.Handlers"
WidthRequest="150">
<Grid.RowDefinitions>
<RowDefinition Height="35"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Frame Grid.Row="0"
...>
<handlers:BorderlessEntry Placeholder="{Binding Source={x:Reference this}, Path=Placeholder}"
WidthRequest="150"
.../>
</Frame>
<AbsoluteLayout
WidthRequest="150"
MaximumHeightRequest="100"
Grid.Row="1"
x:Name="resAl">
<ScrollView
MaximumHeightRequest="100"
MaximumWidthRequest="160"
x:Name="resSV">
<CollectionView x:Name="list">
<CollectionView.ItemTemplate>
<DataTemplate>
<HorizontalStackLayout VerticalOptions="Center"
HorizontalOptions="Start">
<Label Text="{Binding Key}" Padding="0,0,4,0"/>
<Label Text="{Binding Value}"/>
</HorizontalStackLayout>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
</ScrollView>
</AbsoluteLayout>
</Grid>
So, control looking for suggestions in Dictionary while user typing text in Entry. The thing is - when CollectionView updates suggestions it pushes all the other elements on ContentPage down... but suppose to overlay them. All right lets wrap Suggester in AbsoluteLayout on contentPage and setBounds to a desirable position. (PS: Suggester name is suggester 0_o)
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
...
Title=" ">
<AbsoluteLayout x:Name="mainAbs">
<AbsoluteLayout Margin="0,0,0,0"
x:Name="suggestAl">
<suggester:Suggester Placeholder="USD"
SearchDictionary="{Binding SearchCurrency}"
MaximumHeightRequest="150"
MaximumWidthRequest="150"/>
</AbsoluteLayout>
<Grid Padding="10" AbsoluteLayout.LayoutBounds="0,0,1,1"
AbsoluteLayout.LayoutFlags="All">
<ScrollView>
<VerticalStackLayout>
...
<Frame HorizontalOptions="Fill">
<VerticalStackLayout>
...
<VerticalStackLayout HeightRequest="80"
x:Name="currVSL">
<Label Text="Currency out:"
VerticalOptions="Start"
HorizontalOptions="Start"
FontSize="Header"
x:Name="curLbl"/>
**SUggester should be here**
</VerticalStackLayout>
</VerticalStackLayout>
</Frame>
</VerticalStackLayout>
</ScrollView>
</Grid>
</AbsoluteLayout>
</ContentPage>
The first idea is - to grab x:Name="currVSL" bounds, adjust it for size of Label, and place x:Name="suggestAl" there, but i cant get absolute position of x:Name="currVSL" only relative and in absolute terms it's wrong
I don't want to hardcode position in static numbers, because the position highly depends on a particular device.
So the question is how to achieve a desirable result - Place x:Name="currVSL" under the x:Name="curLbl" label.
OR
Might be there is a more elegant solution to show suggestion results without pushing all the other elements down?(Read:overlay other elements on UI)

My ViewModel uses the Maui Community Toolkit and has 4 AsyncCommands defined
LoadCommand
SaveCommand
DeleteCommand
EditCommand
The LoadCommand and SaveCommand work perfectly but the DeleteCommand and EditCommand do not fire. I assume it's something to do with the commands being on the viewmodel and NOT on the item source model. How do I get it to trigger the AsyncCommands on the viewmodel?
Thanks
For this, you can check document Define MenuItem behavior with MVVM.
The MenuItem class supports the Model-View-ViewModel (MVVM) pattern through BindableProperty objects and the ICommand interface. The following XAML shows MenuItem instances bound to commands defined on a viewmodel:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

x:Name="myContentpage"

<viewmodels:ListPageViewModel />
</ContentPage.BindingContext>
<StackLayout>
<Label Text="Reveal the context menu by right-clicking (UWP), long-pressing (Android), or swiping (iOS) an item in the following list." />
<Label Text="{Binding Message}"
TextColor="Red"
HorizontalOptions="CenterAndExpand"
VerticalOptions="Start" />
<ListView ItemsSource="{Binding Items}"
HorizontalOptions="CenterAndExpand"
VerticalOptions="CenterAndExpand">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.ContextActions>
<MenuItem Text="Edit"
IconImageSource="icon.png"
Command="{Binding Source={x:Reference myContentpage}, Path=BindingContext.EditCommand}"
CommandParameter="{Binding .}"/>
<MenuItem Text="Delete"
Command="{Binding Source={x:Reference myContentpage}, Path=BindingContext.DeleteCommand}"
CommandParameter="{Binding .}"/>
</ViewCell.ContextActions>
<Label Text="{Binding .}" />
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</ContentPage>
The viewmodel(ListPageViewModel.cs) contains the commands referenced in the XAML:
public class ListPageViewModel : INotifyPropertyChanged
{
...
public ICommand EditCommand => new Command<string>((string item) =>
{
Message = $"Edit command was called on: {item}";
});
public ICommand DeleteCommand => new Command<string>((string item) =>
{
Message = $"Delete command was called on: {item}";
});
}
I have declared some Datatemplates for my Collectionviews Header to use as an Template.
<ResourceDictionary>

And I'm trying to consume it within my CollectionView with the templateselector :

</CollectionView>
</StackLayout>
</StackLayout>
</AbsoluteLayout>
</ContentPage.Content>
But when I run the Programm I'm always getting "System.InvalidOperationException: 'LoadTemplate should not be null'".
When I'm binding my HeaderTemplate directly like this:
HeaderTemplate="{StaticResource someHeaderTemplate}"
it works just fine.
I've added a log and breakpoint to my TemplateSelector Class but OnSelectTemplate doesn't even get called.
I've also used another Templateselector for my ItemTemplate and that one worked just fine.
Any Help would be appreciated.
In your xaml page, your DataTemplate tag does not add any data or styles, you need to add styles to each DataTemplate tag.
You have not bound the Header data of the CollectionView. You need to add Header="{Binding ViewObjects}" to your CollectionView tag.
This is my xaml code for your reference, I hope it can solve your problem:
<ContentPage.Resources>
<ResourceDictionary>
<DataTemplate x:Key="someHeaderTemplate">
<Label Text="aaa" BackgroundColor="LightPink"></Label>
</DataTemplate>
<DataTemplate x:Key="someOtherHeaderTemplate">
<Label Text="bbb" BackgroundColor="Green"></Label>
</DataTemplate>
<DataTemplate x:Key="someThirdHeaderTemplate">
<Label Text="ccc" BackgroundColor="Yellow"></Label>
</DataTemplate>
<nameSpace:templateSelector x:Key="templateSelector"
first="{StaticResource someHeaderTemplate}"
second="{StaticResource someOtherHeaderTemplate}"
third="{StaticResource someThirdHeaderTemplate}"/>
</ResourceDictionary>
</ContentPage.Resources>
<StackLayout>

Trying to put one image and three label in a row with multiple columns just using flex layout and without nested flex layout, need some help.

fontAttributes="Bold" fontSize={18}/>
<XF.Label text={Bind.twoWays((x) => x.data.description)}

You can use Grid to achieve it:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="50" />
<ColumnDefinition Width="50" />
<ColumnDefinition Width="50" />
</Grid.ColumnDefinitions>
<Image Grid.Row="0" Grid.Column="1" />
<Label text="lbl1" Grid.Row="0" Grid.Column="2" />
<Label text="lbl2" Grid.Row="0" Grid.Column="3" />
<Label text="lbl3" Grid.Row="0" Grid.Column="4" />
</Grid>
In Xamarin Forms (Portable) project when I place RadlistView in first page I got binded list which not render template in Android. I not checked other platforms. In this case the RadListView in second page is rendered ok.
First page with RadListView
Second page with RadListView
But if I replace radlistview in first page with Xamarin.Forms.ListView, it showed normal but in the second page RadListView showed without template.
The first page with Xamarin ListView
Second page with RadListView losted template

c# file not providing because it used web api from another project, also using dummy source has same effect. As source used
ObservableCollection
I forgot add that before issue I updated Telerik Xamarin platform. After clean solution, deleting bin and obj folders and rebild project it solved.
