webform添加修改删除

Webform---修改人员信息 public partial class Edit : System.Web.UI.Page { private MyDBDataContext _Context = new MyDBDataContext(); //绑定民族 private void FillNation() { List<Nation> list = _Context.Nation.ToList(); txtNation.DataSource = list; txtNation.DataTextField = "Name"; txtNation.DataValueField = "Code"; txtNation.DataBind(); } //在修改页面获取人员主键值加载人员信息 private void FillLoadInfo() { string Code = Request["id"]; var query = _Context.Info.Where(p => p.Code == Code); if (query.Count() > 0) { Info data = query.First(); txtCode.Text = data.Code; txtName.Text = data.Name; txtSex.SelectedValue = data.Sex.ToString(); txtNation.SelectedValue = data.Nation; txtBirthday.Text = data.Birthday.Value.ToString("yyyy年MM月dd日"); } } //加载民族和个人信息 protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { FillNation(); FillLoadInfo(); } } //返回显示信息的页面 protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("修改信息.aspx"); } //修改更新信息 protected void btnOk_Click(object sender, EventArgs e) { //查出要修改的对象 string code = txtCode.Text; var query = _Context.Info.Where(p=>p.Code == code); if (query.Count() > 0) { Info data = query.First (); //修改 data.Name = txtName.Text ; data.Sex = Convert.ToBoolean (txtSex.Text); data.Nation = txtNation.Text ; data.Birthday = Convert.ToDateTime (txtBirthday.Text ); //提交 _Context.SubmitChanges(); } } }

Repeater绑定数据：

private MyDBDataContext _Context = new MyDBDataContext(); protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { List<Info> list = _Context.Info.ToList(); Repeater1.DataSource = list; Repeater1.DataBind(); } }

修改信息超链接：

1.a标签：

<a href="Edit.aspx?id=<%#Eval("Code") %>">修改</a>

2.HyperLink按钮

public string ShowHref() { return "Edit.aspx?id=" + Eval("Code"); } <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="<%#ShowHref() %>">修改</asp:HyperLink> </td> Webform---添加删除人员信息 public partial class Add : System.Web.UI.Page { private MyDBDataContext _Context = new MyDBDataContext(); //绑定民族 private void FillNation() { List<Nation> list = _Context.Nation.ToList(); txtNation.DataSource = list; txtNation.DataTextField = "Name"; txtNation.DataValueField = "Code"; txtNation.DataBind(); } //加载民族 protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { FillNation(); } } //点击添加按钮 protected void btnOk_Click(object sender, EventArgs e) { //把界面的值取出来 string code = txtCode.Text; string name = txtName.Text; bool sex = Convert.ToBoolean( txtSex.SelectedValue); string nation = txtNation.Text; DateTime birthday = Convert.ToDateTime( txtBirthday.Text); //送到数据库去 Info data = new Info(); data.Code = code; data.Name = name; data.Sex = sex; data.Nation = nation; data.Birthday = birthday; _Context.Info.InsertOnSubmit(data); _Context.SubmitChanges(); //跳转 Response.Redirect("修改信息.aspx"); } //点击返回按钮 protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("修改信息.aspx"); } }

删除：

1.使用a标签和HyperLink按钮

public string SetKey() { return "Delete.aspx?id=" + Eval("Code"); } //a 标签 <a href ="Delete.aspx?id=<%#Eval("Code") %>" οnclick="return confirm('确认删除？')">删除</a> //HyperLink按钮 <asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl="<%#SetKey() %>">删除</asp:HyperLink> public partial class Delete : System.Web.UI.Page { private MyDBDataContext _Context = new MyDBDataContext(); protected void Page_Load(object sender, EventArgs e) { //找出主键值 string code = Request["id"]; //删除 //找到要删除的项 var query = _Context.Info.Where(p=> p.Code == code); if (query.Count() > 0) { Info data = query.First(); _Context.Info.DeleteOnSubmit(data); _Context.Work.DeleteAllOnSubmit(data.Work); _Context.Family.DeleteAllOnSubmit(data.Family); //提交 _Context.SubmitChanges(); } //跳转 Response.Redirect("修改信息.aspx"); } }

2.使用普通按钮

 

public string Delete() { return Eval("Code").ToString (); } //普通按钮 <asp:Button ID="Button1" OnClick="Button1_Click" CommandArgument="<%#Delete() %>" runat="server" Text="删除" /> private void Show() { List<Info> list = _Context.Info.ToList(); Repeater1.DataSource = list; Repeater1.DataBind(); } //使用普通按钮删除信息 protected void Button1_Click(object sender, EventArgs e) { //找到被点击的删除按钮 Button btn = (Button)sender; //找到按钮上的主键值 string code = btn.CommandArgument.ToString(); //找到要删除的项 var query = _Context.Info.Where(p => p.Code == code); if (query.Count() > 0) { Info data = query.First(); _Context.Info.DeleteOnSubmit(data); _Context.Work.DeleteAllOnSubmit(data.Work); _Context.Family.DeleteAllOnSubmit(data.Family); //提交 _Context.SubmitChanges(); } Show(); }
