点击gridview控件中linkbotton跳转到详细页面进行编辑
>请看到上图“查看详情”这一列，就是今天所说的内容。通过点击编辑链接，将GridView控件这一行的数据加载到编辑页面中，而后就可以进行您所需要的修改了。编辑>列，前台代码示例如下：
???<div style="margin:100px 100px" > ???<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False" BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1" DataKeyNames="uid" DataSourceID="SqlDataSource1" GridLines="None" OnRowCommand="GridView1_RowCommand"> ???????<Columns> ???????????<asp:BoundField DataField="uid" HeaderText="uid" ReadOnly="True" SortExpression="uid" /> ???????????<asp:BoundField DataField="upw" HeaderText="upw" SortExpression="upw" /> ???????????<asp:BoundField DataField="uname" HeaderText="uname" SortExpression="uname" /> ???????????<asp:BoundField DataField="email" HeaderText="email" SortExpression="email" /> ???????????<asp:BoundField DataField="upwe" HeaderText="upwe" SortExpression="upwe" /> ???????????<asp:BoundField DataField="hs" HeaderText="hs" SortExpression="hs" /> ???????????<asp:BoundField DataField="cost" HeaderText="cost" SortExpression="cost" /> ???????????<asp:BoundField DataField="address" HeaderText="address" SortExpression="address" /> ???????????<asp:BoundField DataField="tel" HeaderText="tel" SortExpression="tel" /> ???????????<asp:TemplateField> ???????????????<ItemTemplate> ???????????????????<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument=‘<%# Eval("uid")+","+Eval("upw")+","+Eval("uname")+","+Eval("email")+","+Eval("upwe")+","+Eval("hs")+","+Eval("cost")+","+Eval("address")+","+Eval("tel") %>‘ CommandName="go">编辑</asp:LinkButton> ???????????????</ItemTemplate> ???????????</asp:TemplateField> ???????????<asp:TemplateField> ???????????????<ItemTemplate> ???????????????????<asp:Image ID="Image1" runat="server" Height="150px" ImageUrl=‘<%# Eval("hs") %>‘ Width="150px" /> ???????????????</ItemTemplate> ???????????</asp:TemplateField> ???????</Columns> ???????<FooterStyle BackColor="#C6C3C6" ForeColor="Black" /> ???????<HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" /> ???????<PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" /> ???????<RowStyle BackColor="#DEDFDE" ForeColor="Black" /> ???????<SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" /> ???????<SortedAscendingCellStyle BackColor="#F1F1F1" /> ???????<SortedAscendingHeaderStyle BackColor="#594B9C" /> ???????<SortedDescendingCellStyle BackColor="#CAC9C9" /> ???????<SortedDescendingHeaderStyle BackColor="#33276A" /> ???</asp:GridView> ???<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DesignAndImplementationOfHEYTEAConnectionString %>" SelectCommand="SELECT * FROM [UserInfo]"></asp:SqlDataSource> ???????<asp:Button ID="Button1" runat="server" Text="返回" OnClick="Button1_Click" /> ???</div>>编辑链接的属性CommandArgument有多个参数，其实就是GridView控件中各个列的值。利用GridView控件的RowCommand事件将值传到编辑界面。
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class AdministratorUser : System.Web.UI.Page{ ???protected void Page_Load(object sender, EventArgs e) ???{ ???} ???protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) ???{ ???????if (e.CommandName == "go") ???????{ ???????????????????????string[] estr = e.CommandArgument.ToString().Split(‘,‘); ???????????string uid = Convert.ToString(estr[0]); ???????????string upw = Convert.ToString(estr[1]); ???????????string uname = Convert.ToString(estr[2]); ???????????string email = Convert.ToString(estr[3]); ???????????string upwe = Convert.ToString(estr[4]); ???????????string hs = Convert.ToString(estr[5]); ???????????string cost = Convert.ToString(estr[6]); ???????????string address = Convert.ToString(estr[7]); ???????????string tel = Convert.ToString(estr[8]); ???????????Response.Redirect("AdministratorUserInfo.aspx?uid=" + uid + "&upw=" + upw + "&uname=" + uname + "&email=" + email + "&upwe=" + upwe + "&hs=" + hs + "&cost=" + cost + "&address=" + address + "&tel=" + tel, false); ???????} ???} ???protected void Button1_Click(object sender, EventArgs e) ???{ ???????Response.Redirect("AdministratorMain.aspx"); ???}}>上面的代码就是将GridView控件的行数据值绑定到后台，通过Response.Redirect()跳转再将值传到编辑页面中的各个控件中。需要在编辑页面的后台代码Page_Load()方>法中加载这些被传过来的数据.
>e.CommandArgument.ToString().Split(‘,‘);绑定多值
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Data;using Business;using Entity;public partial class AdministratorUserInfo : System.Web.UI.Page{ ???protected void Page_Load(object sender, EventArgs e) ???{ ???????if (IsPostBack == false) ???????{ ???????????Bind(); ???????} ???} ???public void Bind() ???{ ???????if (Request.QueryString["uid"] == null) ???????{ ???????????Response.Write("<script>alert(‘对不起，请登录！‘),location.href=‘AdministratorLogin.aspx‘</script>"); ???????} ???????else ???????{ ???????????TextBox1.Text = Request.QueryString["uid"].ToString().Trim(); ???????????TextBox2.Text = Request.QueryString["upw"].ToString().Trim(); ???????????TextBox3.Text = Request.QueryString["uname"].ToString().Trim(); ???????????TextBox4.Text = Request.QueryString["email"].ToString().Trim(); ???????????TextBox5.Text = Request.QueryString["upwe"].ToString().Trim(); ???????????Image1.ImageUrl = Request.QueryString["hs"].ToString().Trim(); ???????????TextBox6.Text = Request.QueryString["cost"].ToString().Trim(); ???????????TextBox7.Text = Request.QueryString["address"].ToString().Trim(); ???????????TextBox8.Text = Request.QueryString["tel"].ToString().Trim(); ???????} ???} ???protected void Button1_Click(object sender, EventArgs e) ???{ ???????UserBusiness u = new UserBusiness(); ???????UserEntity ue = new UserEntity(); ???????ue.Uid = TextBox1.Text.Trim(); ???????ue.Upw = TextBox2.Text.Trim(); ???????ue.Uname = TextBox3.Text.Trim(); ???????ue.Email = TextBox4.Text.Trim(); ???????ue.Upwe = TextBox5.Text.Trim(); ???????????????string path = Server.MapPath("~/Image/"); ???????if (FileUpload1.HasFile) ???????{ ???????????string fileName = FileUpload1.FileName; ???????????path += fileName; ???????????string ext = System.IO.Path.GetExtension(path); ???????????ue.Hs = "~/Image/" + fileName; ???????} ???????ue.Cost =TextBox6.Text.Trim(); ???????ue.Address = TextBox7.Text.Trim(); ???????ue.Tel = TextBox8.Text.Trim(); ???????int res = 0; ???????res = u.Update(ue); ???????if (res > 0) ???????{ ???????????Response.Write("<script>alert(‘修改成功！‘),location.href=‘AdministratorUser.aspx‘</script>"); ???????} ???????????} ???protected void Button2_Click(object sender, EventArgs e) ???{ ???????Response.Redirect("AdministratorUser.aspx"); ???}}>Request.QueryString（取得地址栏参数值）获取地址栏中的参数，意思就是取得”？"号后面的参数值．如果是多个是用这”＆”符号连接起来的．

>解释下CommandArgument 获取或设置与关联的 CommandName 属性一起传递到 Command 事件处理程序的可选参数。
>备注
>使用 CommandArgument 属性指定补充 CommandName 属性的参数。
>注意 CommandArgument 属性通常只在设置 CommandName 属性时使用。
>CommandArgument 属性补充 CommandName 属性，允许提供要执行的命令的任何附加信息。例如，可以将 CommandName 属性设置为 Sort 并将 >CommandArgument 属性设置为 Ascending，以指定按升序排序的命令。
