Answer 1

就是 控件能得到，但是 里面的text 值 是空的 这是为什么？ 有没有人遇到这样的问题哈~ 各位大大 帮忙解决哈~~ 很急~~

Answer 2

晕。你的foot里面的控件没有绑定好吧！！！

Answer 3

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

Answer 4

GridViewRow gvr = GridView1.Rows[e.RowIndex] as GridViewRow;
gvr.FindControl("")
这样找

Answer 5

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！！！

Answer 6

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

Answer 7

绑定GridView时候加上：if(!IsPostBack)
{
    //绑定GridView
}
