} private void BindStudent() { string str = ConfigurationManager.ConnectionStrings["stucnn"].ConnectionString; using (SqlConnection sqlCnn = new SqlConnection(str)) { using (SqlDataAdapter da = new SqlDataAdapter("select * from student", sqlCnn)) { DataSet ds = new DataSet(); da.Fill(ds); this.Repeater1.DataSource = ds; this.Repeater1.DataBind(); } } } 删除数据： protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e) { if (e.CommandName == "Delete") { string str = ConfigurationManager.ConnectionStrings["stucnn"].ConnectionString; using (SqlConnection sqlCnn = new SqlConnection(str)) { using (SqlCommand sqlCmm = sqlCnn.CreateCommand()) { sqlCnn.Open(); sqlCmm.CommandText = "delete from student where sid=" + e.CommandArgument.ToString(); sqlCmm.ExecuteNonQuery(); } } this.BindStudent(); } else if (e.CommandName == "Edit") { Server.Transfer("Edit.aspx?sid=" + e.CommandArgument.ToString()); } } 前台： <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <%--<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> <hr /> </HeaderTemplate> <ItemTemplate><div> <asp:Label ID="lblSid" runat="server" Text='<%# Eval("sid") %>'></asp:Label> <asp:Label ID="lblSname" runat='server' Text='<%# Eval("sname") %>'></asp:Label> <asp:Image ID="imgPhoto" runat="server" ImageUrl='<%# Eval("photo") %>' /></div> </ItemTemplate> <SeparatorTemplate> <hr /> </SeparatorTemplate> <AlternatingItemTemplate> <div style="background-color:Olive"> <asp:Label ID="lblSid" runat="server" Text='<%# Eval("sid") %>'></asp:Label> <asp:Label ID="lblSname" runat='server' Text='<%# Eval("sname") %>'></asp:Label> <asp:Image ID="imgPhoto" runat="server" ImageUrl='<%# Eval("photo") %>' /></div> </AlternatingItemTemplate> <FooterTemplate><hr /></FooterTemplate> </asp:Repeater>--%> <div> <asp:Repeater ID="Repeater1" runat="server" onitemcommand="Repeater1_ItemCommand"> <HeaderTemplate><table> <tr><td style="100px">编号</td><td style="100px">姓名</td> <td style="100px">图片</td><td> </td><td> </td></tr> </HeaderTemplate> <ItemTemplate> <tr> <td><%# Eval("sid") %></td><td><%# Eval("sname") %></td> <td><img width="60px" height="60px" src='<%# "images/" + Eval("photo") %>' /></td> <td><asp:LinkButton ID="btnDelete" runat="server" Text="删除" CommandName='Delete' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td> <td><asp:LinkButton ID="btnEdit" runat="server" Text="编辑" CommandName='Edit' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td> </tr> </ItemTemplate> <AlternatingItemTemplate> <tr style="background-color:Green"> <td><%# Eval("sid") %></td><td><%# Eval("sname") %></td> <td><img width="60px" height="60px" src='<%# "images/" + Eval("photo") %>' /></td> <td><asp:LinkButton ID="btnDelete" runat="server" Text="删除" CommandName='Delete' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td> <td><asp:LinkButton ID="btnEdit" runat="server" Text="编辑" CommandName='Edit' CommandArgument='<%# Eval("sid") %>'></asp:LinkButton></td> </tr> </AlternatingItemTemplate> <SeparatorTemplate> <tr><td colspan="5"><hr /></td></tr> </SeparatorTemplate> <FooterTemplate></table></FooterTemplate> </asp:Repeater> </div> </form> </body> </html> 启用，禁用： protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e) { //string status = e.CommandName;
