How to display ObservableCollection content in .net Maui?-CodePudding

I am working on my project and I have encountered a problem. I don't know how to show data from a List.

Code-behind:

public ObservableCollection<GameResult> GameResultsToShow { get; set; } = new ObservableCollection<GameResult>();

public void SortResults()
{

    List<GameResult> SortedGameResults; //to bind 

    if (gameOption.gameType == GameType.Time)
                SortedGameResults = GameResults.FindAll(x => x.gameOption.gameLevel == gameOption.gameLevel && x.gameOption.gameType == gameOption.gameType).OrderBy(x => x.points).ToList();
            else
                SortedGameResults = GameResults.FindAll(x => x.gameOption.gameLevel == gameOption.gameLevel && x.gameOption.gameType == gameOption.gameType).OrderBy(x => x.Time).ToList();


    ObservableCollection<GameResult> GameResultsToShow =new ObservableCollection<GameResult>(SortedGameResults);

        }

Xaml:

<CollectionView 
     ItemsSource="{Binding GameResultsToShow }"
     BackgroundColor="PapayaWhip"
     Margin="10"
     Grid.Row="5"
     Grid.ColumnSpan="3"
     HorizontalOptions="Center">
     <CollectionView.ItemTemplate>
             <DataTemplate>
                   <TextCell Text="{Binding GameResult}"/>
             </DataTemplate>
     </CollectionView.ItemTemplate>
</CollectionView>

CodePudding user response：

ListView can use Cell controls such as TextCell, ViewCell, etc. However, CollectionView can't use Cell controls. Here's the sample code below for your reference:

Xaml:

<ListView   
 ItemsSource="{Binding GameResultsToShow }"
 BackgroundColor="PapayaWhip">
                
    <ListView.ItemTemplate>

       <DataTemplate>
               <TextCell  Text="{Binding GameResultValue}"/>
        </DataTemplate>

    </ListView.ItemTemplate>
</ListView>

Code-behind:

public ObservableCollection<GameResult> GameResultsToShow { get; set; } 


public MainPage()
{
      InitializeComponent();
       
      //Binding the itemsource as Jason suggested
      GameResultsToShow = new ObservableCollection<GameResult>
      {
             new GameResult{GameResultValue = "Win"},
             new GameResult{GameResultValue = "Lose"},
      };

      BindingContext = this;

}

Model:

public class GameResult 
{
    public string GameResultValue { get; set; }
}
