选择例子
前端代码：

<asp:ListView ID="ListView1" runat="server" 
            onselectedindexchanging="ListView1_SelectedIndexChanging">
            <LayoutTemplate>
                <table id="Table1" runat="server" border="0" style="">
                    <tr runat="server" id="itemPlaceholder" />
                </table>
            </LayoutTemplate>
            <ItemTemplate>
                <tr>
                    <td>
                        <%#Eval("ID") %>
                    </td>
                    <td>
                        <asp:Label ID="idLabel" runat="server" Text='<%# Eval("name") %>' />
                    </td>
                    <td>
                        <asp:Label ID="xLabel" runat="server" Text='<%# Eval("age") %>' />
                    </td>
                    <td>
                    <asp:Button ID="SelectButton" CommandName="Select" runat="server" Text="选择" />
                    </td>
                    
                </tr>
            </ItemTemplate>
            <SelectedItemTemplate>
            <tr style="background-color:Blue">
                    <td>
                        <%#Eval("ID") %>
                    </td>
                    <td>
                        <asp:Label ID="idLabel" runat="server" Text='<%# Eval("name") %>' />
                    </td>
                    <td>
                        <asp:Label ID="xLabel" runat="server" Text='<%# Eval("age") %>' />
                    </td>
                    <td>
                    <asp:Button ID="SelectButton" CommandName="Select" runat="server" Text="选择" />
                    </td>
                    
                </tr>
            </SelectedItemTemplate>
       </asp:ListView>

 

后台代码： 

protected void ListView1_SelectedIndexChanging(object sender, ListViewSelectEventArgs e)
    {
        ListView1.SelectedIndex = e.NewSelectedIndex;
        Bind();
    }

 

排序前端代码： 

前端
<asp:ListView ID="ListView1" runat="server" OnSorting="ListView1_Sorting">
            <LayoutTemplate>
                <table id="Table1" runat="server" border="0" style="">
                    <tr>
                        <td>
                            <asp:LinkButton ID="LinkButton1" CommandArgument="ID" runat="server" CommandName="Sort">ID</asp:LinkButton>
                        </td>
                        <td>
                            <asp:LinkButton ID="LinkButton2" CommandArgument="Name" runat="server" CommandName="Sort">Name</asp:LinkButton>
                        </td>
                        <td>
                            <asp:LinkButton ID="LinkButton3" CommandArgument="Age" runat="server" CommandName="Sort">Age</asp:LinkButton>
                        </td>
                    </tr>
                    <tr runat="server" id="itemPlaceholder" />
                </table>
            </LayoutTemplate>
            <ItemTemplate>
                <tr>
                    <td>
                        <%#Eval("ID") %>
                    </td>
                    <td>
                        <%# Eval("name") %>
                    </td>
                    <td>
                        <%# Eval("age") %>
                    </td>
                </tr>
            </ItemTemplate>
        </asp:ListView>

 

排序模拟数据提供代码： 

namespace Data
{
    /// <summary>
    ///DataAccess 的摘要说明
    /// </summary>
    public class DataAccess
    {
        public List<Employee> List;
        public DataAccess()
        {
            List = new List<Employee>();
            Employee e1 = new Employee { ID = 1, Name = "A", Age = 10 };
            Employee e2 = new Employee { ID = 3, Name = "M", Age = 30 };
            Employee e3 = new Employee { ID = 2, Name = "B", Age = 40 };
            Employee e4 = new Employee { ID = 4, Name = "S", Age = 19 };
            Employee e5 = new Employee { ID = 6, Name = "X", Age = 18 };
            Employee e6 = new Employee { ID = 5, Name = "W", Age = 20 };
            List.Add(e1);
            List.Add(e2);
            List.Add(e3);
            List.Add(e4);
            List.Add(e5);
            List.Add(e6);
        }
        public void SortID( string sortDirection)
        {
            if (sortDirection == "ASC")
            {
                List.Sort(new EmployeeIDAscCompare());
            }
            else
            {
                List.Sort(new EmployeeIDDescCompare());
            }
        }
    }
    class EmployeeIDAscCompare:IComparer<Employee>
    {

        #region IComparer<Employee> 成员

        public int Compare(Employee x, Employee y)
        {
            return x.ID.CompareTo(y.ID);
        }

        #endregion
    }
    class EmployeeIDDescCompare : IComparer<Employee>
    {

        #region IComparer<Employee> 成员

        public int Compare(Employee x, Employee y)
        {
            return y.ID.CompareTo(x.ID);
        }

        #endregion
    }
    
    public class Employee
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
        public int Sex { get; set; }
    }
}

 

排序后台代码：

public partial class Default3 : System.Web.UI.Page
{
    DataAccess da;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["da"] == null)
        {
            da = new DataAccess();
            Session["da"] = da;
        }
        else
        {
            da = Session["da"] as DataAccess;
        }
        if (!IsPostBack)
        {
            Bind();
        }
    }
    private void Bind()
    {
        ListView1.DataSource = da.List;
        ListView1.DataBind();
    }
    protected void ListView1_Sorting(object sender, ListViewSortEventArgs e)
    {
        if (String.IsNullOrEmpty(e.SortExpression)) { return; }
        string direction = "";
        if (ViewState["SortDirection"] != null)
            direction = ViewState["SortDirection"].ToString();

        if (direction == "ASC")
            direction = "DESC";
        else
            direction = "ASC";

        ViewState["SortDirection"] = direction;

        da.SortID(direction);
        Bind();
    }
}

 

分页例子：
前端代码： 

 <asp:ListView ID="ListView1" runat="server" OnPagePropertiesChanging="ListView1_PagePropertiesChanging1">
            <LayoutTemplate>
                <table id="Table1" runat="server" border="0" style="">
                    <tr runat="server" id="itemPlaceholder" />
                </table>
            </LayoutTemplate>
            <ItemTemplate>
                <tr>
                    <td>
                        <%#Eval("ID") %>
                    </td>
                    <td>
                        <%# Eval("name") %>
                    </td>
                    <td>
                        <%# Eval("age") %>
                    </td>
                </tr>
            </ItemTemplate>
        </asp:ListView>
    </div>
    <div style="padding: 10px; text-align: right;">
        <asp:DataPager ID="Pager" runat="server" PagedControlID="ListView1" PageSize="2">
            <Fields>
                <asp:NumericPagerField ButtonCount="10" NextPageText="" PreviousPageText="" />
                <asp:NextPreviousPagerField FirstPageText="First" LastPageText="Last" NextPageText="Next"
                    PreviousPageText="Previous" />
            </Fields>
        </asp:DataPager>
    </div>

 

后台代码： 

protected void ListView1_PagePropertiesChanging1(object sender, PagePropertiesChangingEventArgs e)
    {
        Pager.SetPageProperties(e.StartRowIndex, e.MaximumRows, false);
        Bind();
    }
