How to apply sorting to ObservableCollection and DataGrid

BitSmithy 1,951 Reputation points


I have UWP DataGrid and ObservableCollection:

            <controls:DataGrid x:Name="dgTableView" Margin="0,5,0,0"

ObservableCollection<DataRow> dataTable = new ObservableCollection<DataRow>();
dgTableView.ItemsSource = dataTable;

Now I want to apply sorting in sorting event, but I dont want to trigger dgTableView_AutoGeneratingColumn, so I cant change dgTableView.ItemsSource

I tried:

private void dgTableView_Sorting(object sender, Microsoft.Toolkit.Uwp.UI.Controls.DataGridColumnEventArgs e)

dataTable = new ObservableCollection<>(dataTable.OrderBy(x => x.c0))


But those have no effect. How to apply sorting to dataTable without changing ItemsSource, and show it in DataGrid

Below DataRow Class which feeds ObservableCollection:

    public class DataRow : INotifyPropertyChanged
        public string c0 { get; set; } = "";
        public string c1 { get; set; } = "";

    Welcome to Microsoft Q&A!

    So you want to trigger the Sorting event but you don't want the AutoGeneratingColumn event is triggered, is that right?

    I'd suggest you using the AdvancedCollectionView from the Microsoft.Toolkit.Uwp.UI NuGet package as the itemssource instead of directly using the ObservableCollection. The AdvancedCollectionView is a collection view implementation that support filtering, sorting. It could finish the soring work just in the code behind and notify the UI to update. In your scenario, it won't trigger the AutoGeneratingColumn event.


    Here are the steps that you could follow:

    1. Install the Microsoft.Toolkit.Uwp.UI NuGet Package, add using Microsoft.Toolkit.Uwp.UI; into code.
    2. Create a AdvancedCollectionView object from the ObservableCollection<DataRow> object.
    3. Use the AdvancedCollectionView object as the ItemsSource of the DataGrid.
    4. In the Sorting event, using the built-in sorting function of the AdvancedCollectionView object.


    I've made a simple demo to show the specific steps about the usage of AdvancedCollectionView


       <controls:DataGrid x:Name="dataGrid1"   
                               Height="600" Margin="12"  
                               ItemsSource="{x:Bind MyViewModel.Customers}"   


        public sealed partial class MainPage : Page  
            public ViewModel MyViewModel { get; set; }  
            public MainPage()  
                MyViewModel = new ViewModel();  
            private void dataGrid1_Sorting(object sender, DataGridColumnEventArgs e)  
                //Use the header property to pass the bound column name for the sorting implementation  
                if (e.Column.Header.ToString() == "Age")  
                    //Implement sort   
                    if (e.Column.SortDirection == null || e.Column.SortDirection == DataGridSortDirection.Descending)  
                        //Clear pervious sorting    
                        MyViewModel.Customers.SortDescriptions.Add(new SortDescription("Age", SortDirection.Ascending));  
                        e.Column.SortDirection = DataGridSortDirection.Ascending;  
                        MyViewModel.Customers.SortDescriptions.Add(new SortDescription("Age", SortDirection.Descending));  
                        e.Column.SortDirection = DataGridSortDirection.Descending;  
            private void dataGrid1_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)  
        public class ViewModel   
            public AdvancedCollectionView Customers { get; set; }  
            //public ObservableCollection<Customer> Customers { get; set; }  
            public ViewModel()  
                ObservableCollection<Customer> oc = Customer.Customers();  
                Customers = new AdvancedCollectionView(oc, true);  
        public class Customer  
            public String FirstName { get; set; }  
            public String LastName { get; set; }  
            public String Address { get; set; }  
            public Boolean IsNew { get; set; }  
            public int Age { get; set; }  
            public Customer(String firstName, String lastName,  
                String address, Boolean isNew, int age)  
                this.FirstName = firstName;  
                this.LastName = lastName;  
                this.Address = address;  
                this.IsNew = isNew;  
                this.Age = age;  
            public static ObservableCollection<Customer> Customers()  
                return new ObservableCollection<Customer>(new Customer[4] {  
                new Customer("A.", "Zero",  
                    "12 North Third Street, Apartment 45",  
                new Customer("B.", "One",  
                    "34 West Fifth Street, Apartment 67",  
                new Customer("C.", "Two",  
                    "56 East Seventh Street, Apartment 89",  
                new Customer("D.", "Three",  
                    "78 South Ninth Street, Apartment 10",
