Sort Description in DataGrid in Silverlight 3 Application

Introduction

In this article we will see how we can sort one or more DataGrid Colums using SortDescription method.

Creating Silverlight Project

Fire up Visual Studio 2008 and create a Silverlight Application. Name it as SortDescriptionDataGridSL3.



Add a DataGrid into your Application.



Add a class for defining the sample properties of the Sample Data.

public class Users

    {

        public string Name { get; set; }

        public int Age { get; set; }

        public string Gender { get; set; }

        public string Country { get; set; }

    }

Now create some sample data:

List<Users> myList = new List<Users> 
            { 
                new Users{ Name="Hiro Nakamura", Gender="M", Age=24, Country="Japan"},
                new Users{ Name="Mohinder Suresh",Gender="M", Age=26, Country="India"},
                new Users{ Name="Claire Bennette", Gender="F",Age=19, Country="USA"},
                new Users{ Name="Matt Parkman", Gender="M",Age=30, Country="USA"},
                new Users{ Name="Nathan Patrelli", Gender="M",Age=30, Country="USA"},
                new Users{ Name="Peter Patrelli", Gender="M",Age=26, Country="USA"},
                new Users{ Name="Mica", Age=12, Gender="M",Country="USA"},
                new Users{ Name="Linderman", Gender="M",Age=56, Country="USA"},
                new Users{ Name="Ando", Age=24, Gender="M",Country="Japan"},
                new Users{ Name="Maya", Age=24, Gender="M",Country="Mexico"},
                new Users{ Name="Niki Sanders", Gender="F",Age=26, Country="USA"},
                new Users{ Name="Angela Patrelli", Gender="F",Age=26, Country="USA"},
            };

Now create an instance of PagedCollectionView and give parameter as the above list.

PagedCollectionView collection = new PagedCollectionView(myList);

Now add SortDescriptions as follows:

collection.SortDescriptions.Add(new SortDescription("Name", ListSortDirection.Ascending));
collection.SortDescriptions.Add(new SortDescription("Country", ListSortDirection.Ascending));

Now assign the ItemSource of the DataGrid.

MyDataGrid.ItemsSource = collection;

That's it we have successfully used SortDescription. Now run your application to see the Sort Display:



Enjoy Coding.
