GridView点编辑怎么没有反应？怎样实现增加一行的效果？

Question

前台代码：
<asp:GridView ID="GridView_WarningList" runat="server"  CssClass="warninglist" 
        AllowSorting="True" AutoGenerateColumns="False"   DataKeyNames="ID" 
        PageSize="18" AllowPaging="true" 
        onpageindexchanging="GridView_WarningList_PageIndexChanging" 
        onrowcancelingedit="GridView_WarningList_RowCancelingEdit" 
        onrowdeleting="GridView_WarningList_RowDeleting" 
        onrowediting="GridView_WarningList_RowEditing" 
        onrowupdating="GridView_WarningList_RowUpdating">
        <Columns>
       
        <asp:BoundField  DataField="ID"  HeaderText="编号" />
        <asp:BoundField  DataField="Name"  HeaderText="用户名" />
        <asp:BoundField  DataField="Password" HeaderText="密码" />
         <asp:TemplateField HeaderText="用户类型" >
        <ItemTemplate>
            <asp:DropDownList ID="DropDownList_Sort" runat="server">
            <asp:ListItem>普通用户</asp:ListItem>
            <asp:ListItem>超级管理员</asp:ListItem>
            </asp:DropDownList>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:CommandField  HeaderText="选择"  ShowSelectButton="true"/>
        <asp:CommandField  HeaderText="编辑" ShowEditButton="true"/>
        <asp:CommandField  HeaderText="删除" ShowDeleteButton="true"/>
        </Columns>
        <SelectedRowStyle  BackColor="#eeeef6" />
        <PagerStyle  BackColor="#eeeef6" Font-Bold="true" Font-Underline="true" HorizontalAlign="Left"  />
        <HeaderStyle  CssClass="warninglist_header"/>
        <FooterStyle  CssClass="warninglist_footer"/>
    </asp:GridView>后台代码：
public partial class Admin_Users : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                this.bind();
            }
        }
        private void bind()
        {
            BLL_Users users = new BLL_Users();
            DataTable dt = new DataTable();
            dt = users.users_select_all();
            GridView_WarningList.DataSource = dt;
            GridView_WarningList.DataBind();
        }        protected void GridView_WarningList_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            GridView_WarningList.PageIndex = e.NewPageIndex;
            this.bind();
        }        protected void GridView_WarningList_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {        }        protected void GridView_WarningList_RowEditing(object sender, GridViewEditEventArgs e)
        {        }        protected void GridView_WarningList_RowUpdating(object sender, GridViewUpdateEventArgs e)
        {        }        protected void GridView_WarningList_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
        {        }}问题一：为什么点击编辑按钮了，但是页面没有反应，没有出现编辑的文本框？
问题二：怎样实现增加一行的功能，也就是在某处点击按钮，然后GridView可以多出一行，以便用户增加新的信息记录，这样可以实现吗？

Answer 1

问题1
要在GridView_WarningList_RowEditing事件里加上
GridView1.EditIndex = e.NewEditIndex;
this.bind();
问题2实现插入功能 然后从新绑定gridview即可

Answer 2

<ItemTemplate>   
<%# Eval("name") %>   
</ItemTemplate>   
<EditItemTemplate >   
<asp:TextBox ID="TextBox1" runat="server" Text=' <%# Eval("name") %>' width="50"> </asp:TextBox>   
</asp:TextBox>   
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="edit" CausesValidation="false" OnClientClick="return confirm('确认要编辑吗？');">编辑</asp:LinkButton>
  <asp:LinkButton ID="LinkButton2" runat="server" CommandName="delete" CausesValidation="False" OnClientClick="return confirm('确认要删除吗？');">删除</asp:LinkButton>
  <asp:LinkButton ID="LinkButton3" runat="server" CommandName="Select" CausesValidation="False" Visible="false" >选取</asp:LinkButton>
</ItemTemplate>  protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)   
  {   
  gv.EditIndex = e.RowIndex;
   
  string str= ((TextBox)gv.Rows[e.RowIndex].FindControl("TextBox1")).Text.Trim();   
  }

Answer 3

Gridview增删改查分业还是用
ASPNETPAGER

Answer 4

“ASPNETPAGER”控件在“aspx.cs”文件中的方法体内，不能识别它的“ID”，而且控件已经注册好
