ASP.NET 中如何实现删除、修改这些功能啊？

Answer 1

用GridView自带的删除、修改就应该在GridView事件里写

    --前台这样写

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

<asp:GridView ID="GridView1" runat="server" Width="70%" AutoGenerateColumns="False" Font-Size="Small" OnRowDataBound="GridView1_RowDataBound" OnRowCommand="GridView1_RowCommand" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" PageSize="15">        <Columns>            <asp:BoundField DataField="Number" HeaderText="列名1" />            <asp:BoundField DataField="BedNumber" HeaderText="列名2" />            <asp:BoundField DataField="Description" HeaderText="列名3" />            <asp:BoundField DataField="StateName" HeaderText="列名4" />            <asp:BoundField DataField="GuestNumber" HeaderText="列名5" />            <asp:BoundField DataField="TypeName" HeaderText="列名6" />                         <asp:TemplateField HeaderText="修改">                <ItemTemplate>                     <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="image/edit.gif"  CommandName="Ed" CommandArgument=<%#Eval("标识列") %>>                                      </asp:ImageButton>                </ItemTemplate>                </asp:TemplateField>                                             <asp:TemplateField HeaderText="删除">                <ItemTemplate>                     <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="image/delete.gif" CommandName="De" CommandArgument=<%#Eval("标识列") %>>                                      </asp:ImageButton>                </ItemTemplate>                </asp:TemplateField>                     </Columns>    </asp:GridView

   

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

--后台这样：   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)    {        int i;        //执行循环，保证每条数据都可以更新        for (i = 0; i < GridView1.Rows.Count; i++)        {            //首先判断是否是数据行            if (e.Row.RowType == DataControlRowType.DataRow)            {               ImageButton imgbtn = (ImageButton)e.Row.FindControl("ImageButton1");                imgbtn.Attributes.Add("onclick","return confirm('您确认要删除吗?');");              }        }    }   protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)    {        string cmd = e.CommandName;        int Id = Convert.ToInt32(e.CommandArgument);        if (cmd == "De")        {            //这是调用的删除方法，根据标识列            RoomManager.DeleteRoomByRoomId(Id);        }        else if(cmd=="Ed")        {                       //这是跳转到其他页面修改            Page.Server.Transfer("UpdateRooms.aspx?RoomId=" + Id.ToString());        }        binddate();//重新绑定GridView    }
