Can not get SfAutoComplete to bind to Object

[Gregor]

Hello,

I am trying to use SfAutoComplete with data binding its source to Objects. I can not get values and I receive (in Visual Studio 2019) Xaml binding failure.

SfAutoComplete.AutoCompleteSource List`1 'System.Collections.Generic.List`1[ExpenseTracker.Model.Account]' cannot be converted to type 'System.Collections.Generic.List`1[System.String]'

My Object is defined in Model and bindings works because on same Page i have picker and it is populated with Object (ObservableCollection). I am using FreshMVVM. Does anyone have any solution?

My XAML code (page)

xmlns:autocomplete="clr-namespace:Syncfusion.SfAutoComplete.XForms;assembly=Syncfusion.SfAutoComplete.XForms"

xmlns:ListCollection="clr-namespace:System.Collections.Generic;assembly=netstandard"

xmlns:inputLayout="clr-namespace:Syncfusion.XForms.TextInputLayout;assembly=Syncfusion.Core.XForms"

xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

xmlns:expensetracker="clr-namespace:ExpenseTracker"

x:Class="ExpenseTracker.SettingsPage">

SuggestionMode="Contains"

AutoCompleteMode="SuggestAppend"

AutoCompleteSource="{Binding Accounts}">

FontSize="20"

VerticalTextAlignment="Center"

HorizontalOptions="Center"

VerticalOptions="Center"

TextColor="#006bcd" />

ItemDisplayBinding="{Binding AccountName}"/>

ViewModel (PageModel in FreshMVVM)

using ExpenseTracker.Model;

using ExpenseTracker.Services;

using FreshMvvm;

using System;

using System.Collections.Generic;

using System.Collections.ObjectModel;

using System.Text;

using System.Threading.Tasks;

namespace ExpenseTracker

{

class SettingsPageModel : FreshBasePageModel

{

public async override void Init(object initData)

{

await LoadAllData();

}

// Tasks

async Task LoadAllData()

{

DatabaseConnection database = await DatabaseConnection.Instance;

var a = await database.GetAllAccounts();

//testing

a.Add(new Account() { AccountID = 0, AccountName = "Test1", AccountType = "Type1" });

a.Add(new Account() { AccountID = 1, AccountName = "Test2", AccountType = "Type2" });

a.Add(new Account() { AccountID = 2, AccountName = "Test3", AccountType = "Type1" });

a.Add(new Account() { AccountID = 3, AccountName = "Test4", AccountType = "Type1" });

// End of testing

Accounts = new ObservableCollection(a);

var c = await database.GetAllCategories();

Categories = new ObservableCollection(c);

}

// Properties

private ObservableCollection accounts;

public ObservableCollection Accounts

{

get => accounts;

set

{

accounts = value;

RaisePropertyChanged();

}

}

private ObservableCollection categpries;

public ObservableCollection Categories

{

get => categpries;

set

{

categpries = value;

RaisePropertyChanged();

}

}

}

}

Thank you for provided example. After analyzing I was able to found an error - I was using  AutoCompleteSource and not DataSource.
