C# code

    protected void baocun_Click(object sender, EventArgs e)    {        TextBox UserLogins = GridView1.FooterRow.FindControl("UserLogins") as TextBox;        TextBox UserPwds = GridView1.FooterRow.FindControl("UserPwds") as TextBox;        TextBox Xzhes = GridView1.FooterRow.FindControl("Xzhes") as TextBox;        users use = (users)Session["user"];        users us = new users();        us.UserLogin = UserLogins.Text.Trim();        us.UserPwd = UserPwds.Text.Trim();        string zs = Xzhes.Text.Trim();        us.Xzhe = double.Parse(Xzhes.Text.Trim());        us.UserJao = 0;        us.Adress = "";        us.Email = "";        us.MSN = "";        us.Phone = "";        us.UserDate = DateTime.Now.ToString();        us.UserName = "";        us.UserSex = "男";        us.UserState = 1;        int num = userService.InsertUser(us, use.UserID);        if (num > 0)        {            Response.Write("<script>alert('添加成功！');location='myqu.aspx'</script>");        }    }

[解决办法]
晕。你的foot里面的控件没有绑定好吧！！！
[解决办法]
那我觉得就是
TextBox UserLogins = GridView1.FooterRow.FindControl("UserLogins") as TextBox;
TextBox UserPwds = GridView1.FooterRow.FindControl("UserPwds") as TextBox;
TextBox Xzhes = GridView1.FooterRow.FindControl("Xzhes") as TextBox;
的问题。
不能这样查找

你要查找你点击的当前行，再从这行查找控件，再取控件的值

[解决办法]
还有你用的几个事件貌似都有问题吧。
比OnRowDeleting这个事件。应该是OnRowDeleted吧！！！
[解决办法]
TextBox UserLogins = GridView1.FooterRow.FindControl("UserLogins") as TextBox;
TextBox UserPwds = GridView1.FooterRow.FindControl("UserPwds") as TextBox;
TextBox Xzhes = GridView1.FooterRow.FindControl("Xzhes") as TextBox;
users use = (users)Session["user"];
users us = new users();
us.UserLogin = UserLogins.Text.Trim();

=>

C# code

TextBox UserLogins = GridView1.FooterRow.FindControl("UserLogins") as TextBox;                users us = new users();if(UserLogins!=null){        us.UserLogin = (Request.Form[UserLogins.UniqueID]??"").ToString().Trim();}
[解决办法]
探讨

我设置了 文本的值的话 后台 可以获得 但是 用户输入的数据 后台获得不了 还是原来的值
