Question

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

<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

   

 --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
   }
