I have a DataGrid in WPF app with several columns, including a Score column.I want the data to be sorted by the Score.

Is it possible sort DataGrid ?

Wpf Code:

        <DataGrid Name="datagrid_BergretterHighscore" Margin="5,5,5,5" AutoGenerateColumns="False">
            <DataGrid.Columns>
                    <DataGridTextColumn Binding="{Binding Vorname}" Header="Vorname" />
                    <DataGridTextColumn Binding="{Binding Nachname}" Header="Nachname" />
                    <DataGridTextColumn Binding="{Binding Score}" Header="Score" SortDirection="Descending" />
            </DataGrid.Columns>
         
        </DataGrid>       

C# Code:

 namespace PistenDIenstListe_Views.HighscorePage
 {
    

    public partial class Highscore : Page
    {
        private static PistenDienstDB context = new PistenDienstDB();
        BergretterData bergretterData = new BergretterData(context);

        public Highscore()
        {
            InitializeComponent();

            datagrid_BergretterHighscore.ItemsSource = bergretterData.Read();
            datagrid_BergretterHighscore.IsReadOnly = true;

        }


    }
 } 

CodePudding user response：

You must use the default ICollectionView of the ItemsControl (Collection views). Since you handle the DataGrid directly, you can reference the view returned by the ItemsControl.Items property for this purpose:

public partial class Highscore : Page
{
  private static PistenDienstDB context = new PistenDienstDB();
  BergretterData bergretterData = new BergretterData(context);

  public Highscore()
  {
    InitializeComponent();

    dataGrid_BergretterHighscore.ItemsSource = bergretterData.Read();
    dataGrid_BergretterHighscore.IsReadOnly = true;

    // Sort the DataGrid programmatically
    var sortDescription = new SortDescription(nameof(MyDataObject.Score), ListSortDirection.Descending);
    dataGrid_BergretterHighscore.Items.SortDescriptions.Add(sortDescription);
  }
}
