ASP.NET ListView控件學習系列2-編輯ListView（Edit,Update,Insert,Delete）

一、編輯，取消，更新操作

首先拖一個ListView控件到頁面,然後按如下代碼進行調整,這裡為了利用ListView控件中按鈕的內置功能CommandName必須和我們這裡的名字一樣

前端代碼

<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>

這裡我們在App_Code文件夾中添加DataAccess類來模擬數據提供,代碼如下:

模擬數據提供代碼

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; }
}
