ASP.NET ListView控件学习系列2-编辑ListView（Edit,Update,Insert,Delete）

一、编辑，取消，更新操作

首先拖一个ListView控件到页面,然后按如下代码进行调整,这里为了利用ListView控件中按钮的内置功能CommandName必须和我们这里的名字一样

前端代码

<asp:ListView ID="ListView1" runat="server" OnItemEditing="ListView1_ItemEditing"            OnItemCanceling="ListView1_ItemCanceling" OnItemUpdating="ListView1_ItemUpdating">            <ItemTemplate>                <tr>                    <td>                        <%#Eval("ID") %>                    </td>                    <td>                        <%#Eval("name") %>                    </td>                    <td>                        <asp:Button ID="EditButton" runat="server" Text="Edit" CommandName="Edit" />                    </td>                </tr>            </ItemTemplate>            <EditItemTemplate>                <tr>                    <td>                        <asp:Label ID="IDLable" runat="server" Text='<%#Eval("ID") %>' />                    </td>                    <td>                        <asp:TextBox ID="NameTextBox" runat="server" Text='<%#Bind("Name") %>' />                    </td>                    <td>                        <asp:Button ID="UpdateButton" runat="server" CommandName="Update" Text="Update" />                        <asp:Button ID="CancelButton" runat="server" CommandName="Cancel" Text="Cancel" />                    </td>                </tr>            </EditItemTemplate>            <LayoutTemplate>                <table>                    <tr runat="server" id="itemPlaceholder">                    </tr>                </table>            </LayoutTemplate>        </asp:ListView>

这里我们在App_Code文件夹中添加DataAccess类来模拟数据提供,代码如下:

模拟数据提供代码

public class DataAccess{    public List<Employee> List;    public DataAccess()    {        List = new List<Employee>();        Employee e1 = new Employee {ID=1, Name = "lfm1", Age = 30 };        Employee e2 = new Employee {ID=2, Name = "lfm2", Age = 30 };        Employee e3 = new Employee {ID=3, Name = "lfm3", Age = 30 };        Employee e4 = new Employee {ID=4, Name = "lfm4", Age = 30 };        Employee e5 = new Employee {ID=5, Name = "lfm5", Age = 30 };        Employee e6 = new Employee {ID=6, Name = "lfm6", Age = 30 };        List.Add(e1);        List.Add(e2);        List.Add(e3);        List.Add(e4);        List.Add(e5);        List.Add(e6);    }}public class Employee{    public int ID { get; set; }    public string Name { get; set; }    public int Age { get; set; }    public int Sex { get; set; }}
