SortDirection Enumeration

Note: This enumeration is new in the .NET Framework version 2.0.

Specifies the direction in which to sort a list of items.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public enum SortDirection
public enum SortDirection
public enum SortDirection

 Member nameDescription
AscendingSort from smallest to largest. For example, from A to Z. 
DescendingSort from largest to smallest. For example, from Z to A. 

The SortDirection enumeration is used to represent the direction in which items are sorted. It is commonly used by properties (such as the SortDirection property of the GridView class) to indicate the order in which items are displayed in a control.

The following code example demonstrates how to use the SortDirection enumeration to determine the direction in which the GridView control is displaying its items. The SortDirection property of the GridView control is tested for its value to determine the sort direction.

<%@ Page language="C#" %>

<script runat="server">

  void AuthorsGridView_Sorted(Object sender, EventArgs e)
    // Display the sort direction.   
    if(AuthorsGridView.SortDirection == SortDirection.Ascending)
      Message.Text = "Sorting in ascending order.";
      Message.Text = "Sorting in descending order.";


    <form runat="server">
      <h3>SortDirection Example</h3>
      <asp:label id="Message"
      <asp:gridview id="AuthorsGridView"
      <!-- This example uses Microsoft SQL Server and connects -->
      <!-- to the Pubs sample database.                        -->
      <asp:sqldatasource id="AuthorsSqlDataSource"  
        selectcommand="SELECT [au_id], [au_lname], [au_fname], [address], [city], [state], [zip], [contract] FROM [authors]"
        updatecommand="UPDATE authors SET au_lname=@au_lname, au_fname=@au_fname, address=@address, city=@city, state=@state, zip=@zip, contract=@contract WHERE (authors.au_id = @au_id)"
        connectionstring="server=localhost;database=pubs;integrated security=SSPI"
