ASP.NET ListView控件基本操作
1、前台代码
View Code
1 <asp:ListView ID="lvDepartment" runat="server" DataKeyNames="F_DepartmentID" EnableModelValidation="True"
2 InsertItemPosition="LastItem" oniteminserting="lvDepartment_ItemInserting"
3 onitemediting="lvDepartment_ItemEditing"
4 onitemcanceling="lvDepartment_ItemCanceling"
5 onitemdeleting="lvDepartment_ItemDeleting"
6 onitemupdating="lvDepartment_ItemUpdating">
7 <AlternatingItemTemplate>
8 <tr style="">
9 <td>
10 <asp:Button ID="DeleteButton" runat="server" CommandName="Delete" Text="删除" onclientclick="return confirm('确认删除？')"/>

16 </td>
17 <td>

19 </td>
20 </tr>
21 </AlternatingItemTemplate>
22 <EditItemTemplate>
23 <tr style="">

2、后台代码
View Code
1 public partial class department : Mis.PageBase
2 {
3 protected void Page_Load(object sender, EventArgs e)
4 {
5 if (!IsPostBack&&configcompany!=null)
6 {
7 lvDepartmentBind();
8 }
9 }
10
11 protected void lvDepartment_ItemInserting(object sender, ListViewInsertEventArgs e)
12 {
13 TextBox txDepart = (TextBox)e.Item.FindControl("F_DepartmentNameTextBox");
14 TextBox txOrder = (TextBox)e.Item.FindControl("F_OrderTextBox");
15 if (txDepart.Text == "")
16 {
17 lbMessage.Text = "部门不能为空";
18 }
19 else if (txOrder.Text == "")
20 {
21 lbMessage.Text = "没有填写顺序";
22 }
23 else
24 {
25 bool bl = Mis.GetUserInfo.InsertDepartment(txDepart.Text, Convert.ToInt32(txOrder.Text), configcompany.CompanyID);
26 lvDepartmentBind();
27 HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath);
28 }
29 }
30
31 protected void lvDepartment_ItemEditing(object sender, ListViewEditEventArgs e)
32 {
33 lvDepartment.EditIndex = e.NewEditIndex;
34 lvDepartmentBind();
35 HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath);
36 }
37
38 protected void lvDepartment_ItemDeleting(object sender, ListViewDeleteEventArgs e)
39 {
40 int KeyId = Convert.ToInt32(lvDepartment.DataKeys[e.ItemIndex].Value);
41 bool bl = Mis.GetUserInfo.DeleteDepartment(KeyId);
42 lvDepartmentBind();
43 HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath);
44 }
45
46 protected void lvDepartment_ItemUpdating(object sender, ListViewUpdateEventArgs e)
47 {
48 int KeyId = Convert.ToInt32(lvDepartment.DataKeys[e.ItemIndex].Value);
49 TextBox txDepart =(TextBox)lvDepartment.Items[e.ItemIndex].FindControl("F_DepartmentNameTextBox");
50 TextBox txOrder =(TextBox)lvDepartment.Items[e.ItemIndex].FindControl("F_OrderTextBox");
51 if (txDepart.Text=="")
52 lbMessage.Text ="部门不能为空";
53 else if(txOrder.Text=="")
54 lbMessage.Text="顺序不能为空";
55 else
56 {
57 string depart =Server.HtmlEncode(txDepart.Text);
58 int order = Convert.ToInt32(txOrder.Text);
59 bool bl = Mis.GetUserInfo.UpdateDepartment(depart,order,KeyId);
60 lvDepartment.EditIndex = -1;
61 lvDepartmentBind();
62 HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath);
63 }
64 }
65
66 protected void lvDepartment_ItemCanceling(object sender, ListViewCancelEventArgs e)
67 {
68 //取消编辑
69 if (e.CancelMode == ListViewCancelMode.CancelingEdit)
70 {
71 //e.Cancel = true;
72 lvDepartment.EditIndex = -1;
73 lvDepartmentBind();
74 HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath);
75 }
76 else if (e.CancelMode == ListViewCancelMode.CancelingInsert)
77 {
78 lvDepartmentBind();
79 HttpContext.Current.Response.Redirect(HttpContext.Current.Request.Url.AbsolutePath);
80 return;
81 }
82 }
83 protected void lvDepartmentBind()
84 {
85 lvDepartment.DataSource = Mis.GetUserInfo.ReadDepartmentList(configcompany.CompanyID);
86 lvDepartment.DataBind();
87
88 }
89 }
注释：Mis.PageBase：封装了页面登陆判断等一些信息；具体数据的处理，像插入数据库库、数据判断等在其他封装类里实现。
这两段代码只是listview控件的一些基本的操作！
